  1. On a similar topic, and I haven't searched because it's just come to me, if you built a scratch built car, And registered it now as new, does it need a cat fitted?
  2. The old Barry at VINZ that the receptionist threw onto the phone was also adamant that there was no difference in the process for pre and post 1991 cars, despite NZTA making it clear there is (and VTNZ confirming they abide by that also, with a lower cost (sub $300) and less invasive inspection for pre-91 cars). I would avoid VINZ Lower Hutt like the plague if youre looking to re-rego a classic car.
  3. Slowly working on getting the Mini registered. Been calling around, and have determined the vtnz is the way to go, and Vinz are rip off cunts. Vinz trying to charge twice as much as vtnz, and take twice as long.
  4. Could you use grease and a punch to hydraulic it out? Much like you do for pilot/spigot bushing
  5. Crazy small world. Saw this on the truck in Lower Hutt he other day, looked awesome.
  6. Yeah im going to look into a small filter like that, to go inline in the hose. I doubt it will be an issue again, as i suspect it was an issue from back before i got the car, but best to protect it anyway. I have created a small drip loop in the hose before the sensor, so the sensor is above the hose, and angled the ECU slightly downwards (so the sensor can self drain) I have heard though that running a filter on a MAP line can slow the response of the sensor?
  7. Further to the last couple of posts, driving Tess I still noticed a small hesitation coming on throttle. It was a lot better, but still there. The next logical step was to remove the ECU and inspect the MAP sensor, and see if there was oil in it. Sure enough, upon inspection, there was indeed oil in the MAP sensor. Lame. I tried soaking it out with brake clean, and sucking it out with a syringe, but still couldnt clear it. The trick was to turn the ECU upside down, and gently heat the MAP sensor up so the oil would thin out, and then gravity just drained it out drip by drip. I cleaned up some surface rust on the ECU bracket, gave it a quick shot of paint and reinstalled. Testing confirms the issue appears sorted, with no hesitation coming off and on throttle. The throttle response is now snappy and the slight rich mixture it had when coming on throttle is much lessened. Great success. Now to start my new job so I can afford to fuel the beast again.
  8. Rear track is 1510mm, car width is 1770mm
  9. Just pondering. The rear axle and torque tube setup on SD1s is pretty average (LSDs are uncommon and expensive, no provision for any sort of swaybar, the torque tube splines wear and are NLA now, and they dont handle much torque) If one was to want to swap to a conventional live rear axle, from something else a bit more common, can anyone that of one that might fit with minimal mods to mountings? I know the hilux axles were a common swap into things like starlets. I dont know if those are still the go to? Im guessing shock, spring and radius arm mounts can be added to most live axles to suit the SD1
  10. It did work, somehow. You bleed the two together, and then you bleed the third one afterwards. Three nipples, and not even the good kind.
  11. Belong to new page. Anyway, The other interesting fact, is that there is no oil in the hose from either the plenum to the tee, or the hose from the tee to the FPR, or for that matter, in the Tee itself. Only oil in the MAP line. I had a think about this, and suspect the oil has been in there for longer than I have had the car, as when i first got it, the MAP vacuum hose was on its own nipple in the plenum (someone had drilled it out to add a new nipple); when i swapped plenums when i first got the car, the replacement only had the standard single outlet for the FPR, so i teed off and connected the MAP to that Tee (the same as i did when i converted Effie to Speeduino). Thus, i can conclude, that the oil had been in the hose for ages and it isnt new. Its only either gotten thicker and started causing issues now, or had congregated somewhere in the hose and blocked it.
  12. All your base...
  13. Whoop
  14. Derp
  15. Bump
  16. THis page is huge. New plz.
  17. Its not crazy like the AP calipers on a Vitesse, where both bleed nipples on each caliper need to be bled at the same time?
  18. I know, and i totally knew this. Checking the hose where it tees off to the FPR was the first thing i checked, but no cracks so i moved on. Downside to having to live with the hand controller only i guess. So used to seeing everything in realtime on Tunerstudio, without having to hold a button and see a single reading at a time.
  19. Well damn. Got a harsh lesson in the KISS principle today. As above, I replaced the fuel pump and filters recently as i ran the car low on gas and it started to show hesitation when coming on throttle. There was fine metal in the fuel filter, likely from the pump, so i swapped it with another pump i had. I also fitted a pre-pump filter, to make sure no crap from the tank gets into the filter. The good news is that the inside of the tank is not rusty, and the fuel sender now works properly. Anyway, so i thought the issue was fixed, but then its been popping up randomly until a couple of days ago when i went to go help a friend with their car, and Tess got very grumpy on the way home, almost stalling when trying to take off at intersections, and if you didnt roll on the throttle slowly it would fall flat on its face, backfire and carry on until it cleared and would rev happily to limiter. I checked all the plugs, all very black (i only cleaned them the other day) and a couple of them wet with fuel. I replaced them with new ones, issue remained. I checked all injectors were working, they were all firing OK. I reinstalled the air intake back in front of the radiator, no change. I removed and cleaned the cap and rotor, no change. Checked for vacuum leaks around inlet manifold, none. Cleaned idle control valve, no change. Removed idle control valve and bypassed, no change. Re-wired idle control valve as plug was damaged, no change. Resistance tested all leads, all OK. Resistance tested coil, OK. Stripped down coil and amplifier unit, and swapped parts from another unit I had, after thoroughly cleaning all parts. No change. WTF. I then stood back and thought, "damn, its almost like when Effie didnt have enough acceleration enrichment in the tune, I wonder what the ECU is seeing on the MAP sensor". A quick check on the hand controller, and BAM, the MAP reading was all over the show when the throttle was blipped and wasnt responding as quick as it shouldve been. I removed the vacuum line to the MAP sensor, which also Tees off the FPR, and inspected it. No cracks, no holes, nothing. I tested it for holding a vacuum with a hand pump, held well. I was about to reinstall it again and admit defeat for the day when suddenly a small dribble of oil came out of the end of the vacuum hose. Well damn, WTF? I squirted some brake clean down the hose and it took a fair bit to come out the end of the hose. Eventually it came through as solid black, slimey and with some lumps. It took a lot of brake clean to clear the hose and run clear again; lots of oil in the hose. The hose was refitted, and I fired the car up again. It fired straight up, and the MAP reading on the hand controller was much more stable and quick to respond. A couple of blips of the throttle and there was a little stutter, but once the plugs cleared it showed no signs at all of hesitating when giving it throttle. I took it for a drive, and no matter how hard i came on the throttle, even taking it up a steep hill, she just pulled hard. So, in conclusion, I probably didnt need to replace the fuel pump, it obviously wasn't too bad and was just a coincidence that the car started to run badly when i was low on fuel. The vacuum line, which is the main "load" feed for the ECU was full of blow-by oil. So a tip to anyone that is running a remote map sensor, make sure you keep your vacuum hose clean. KISS. Keep It Simple, Stupid.

    Battery chargers

    Also had to "jumpstart" the battery charge on my 5A Ctek before, but that was for a 6v motorbike battery that had been at 0v for about 5 years. It did manage to charge it, but the battery was poked and didnt hold a charge long. Big fan of the Ctek chargers, quick, reliable and simple. A lot of brands use Ctek as their official branded charger too. All the chargers we had at Mercedes were Ctek, albeit the massive top of the line ones.
  21. I love looking at random stuff with microscopes. I know it sounds gross, but a wart looks like a martian landscape under one lol
  22. From what i remember of tuning my car, you shouldnt be relying on auto tune to tune the idle. Do that manually, and then block out auto tune from touching that area. If you havent already, it would be worth you going over the MS manuals, as they have some really good information on setup and tuning.
  23. Tess has been a bit grumpy recently, and it was probably my own silly fault, but now I have to fix it. I took Tess for a WOF inspection the other day, which she passed, of course. I did need to clean the reflector on one of the tail lights as it was completely obscured by dust, but that was as easy as blasting the inside of the light out with compressed air through the bulb holes. It was pretty bad, I don't blame them for failing it For comparison, the RH side with the nice clear reflector (I'd say the light was replaced at some point. it's too, clean.) The result isn't perfect, but the reflector is actually visible now. Not sure how critical a LH side rear reflector is, but hey. Moving along; I was a bit silly with the WOF. I didn't have the money for a tank of gas (not 60L of 98oct at these prices), so I chose to take it for the WOF with somewhere in the vicinity of 1/8 of a tank. Maybe 1/4 at the most. The fuel gauge is a bit of a joke, it consistently reads about 1/4 low so on the lower end of the dial it's anyone's guess what's in the tank. The WOF was fine, but driving the car shortly after that (a celebratory WOF passed hoon) it developed an annoying stutter/hesitation when quickly pressing the throttle. If you rolled the throttle on it would rev out and drive fine, but if you jabbed the throttle too quick, like when rev matching or changing gear spiritedly, it would fall flat on its face for a bit, possibly pop out the exhaust and then come back to life and rev fine. I tried adding some more gas to the tank, but obviously I had made her mad. This gave me a huge sinking feeling.... the car had been sitting for years before I got her, was the tank full of rust? Had rust blocked the filter? The first step for me was to see if the fuel pump might have been mad. Its been making weird noises since I got the car. When you first turn the key and the pump primes, 1/4 of the time it would make a normal buzzing sound, but often it would just make a series of clicking noises. It still seemed to work, but you had to prime the system twice when cold or the car was hard to start. One prime, lots of cranking. Two primes, instant start. The Rover SD1 EFI system runs a big resistor on the power feed for the fuel pump, which drops the voltage so the pump runs quieter with less output. These pumps are basically the same as the infamous Bosch "070" pump as used on fabulous machines such as the V12 Jaaag XJS, and the VL Commodore "tsutsutsu" turbo. Good for something like 300-400hp apparently, so obviously not stressed on the old 190hp RV8. Because my car is running an aftermarket LinkECU, but has the standard loom adapted, I had no idea if it was still running the resistor or not. In Effie I bypassed it when the Speeduino was fitted. The resistor lives up at the base of the LH A pillar, next to the glove box. Remove the glove box and it should be bolted into an oval cut out. I had already removed the bolt in this photo. Some wiggling with the bolt out and it will come out I made a quick bypass out of some genuine Lucas wire, and two spade terminals Unplug the resistor, plug the bypass in The good news was that the fuel pump made lovely buzzing noises all every time now, and you only needed the prime the system once and the car would fire into life without issue. The bad news, was that the hesitation was still there. The next step here was to check the fuel filter. The SD1 has a particulate filter in the fuel tank, on the outlet pipe (more on that later), and a fine EFI filter in the engine bay. I replaced the EFI filter when I got Tess, so anything in it would have been since then. I removed the filter and drained it backwards, from the inlet, into a clean jar. It looks like someone poured fine glitter in my fuel. It wasn't rusty, it was silver, and ferrous. I swirled a magnet around in the jar and this is what came out (looks kinda brown here, but in person it was shiny silver) Well that's good and bad I guess. No rust means the it may not have sucked up rust, but metal filings mean the fuel pump is probably poked. I cut the end off the filter and opened it up to check. Nothing else in it, just more fine glitter on the paper. Nice to see the Ryco filter has a plastic cage to stop the paper being crushed. The clicking noise made me wonder, and the glitter confirmed it, the fuel pump wasn't a happy chappy. Thankfully I have a spare, original fuel pump. I wasn't sure how good it was, but it did come alive when 12v was shoved into it. Before replacing the pump there was one other quick check to do, remove the fuel level sender and check the inside of the tank. There is an access hole in the bump behind the rear seats, on the LH side. It has a large rubber plug in it covering the sender and wiring Mine was covered in crud, but that soon loosened when I got the hammer out to remove the retaining ring. The retaining ring has three tabs sticking up from it. I used a screwdriver and hammer to tap it around anti-clockwise with the tabs. There are three cutouts in the retainer, that will line up with three bumps on the tank housing, and when lined up you can remove the retainer I gave the area a quick vacuum so that crud didn't end up in the tank. With the retainer out, and the connections off, the sender can be lifted out, being careful of the float So, with bated breath I shone a light into the tank and had a look. Well I'll be. Nothing but clean metal, even on the sides of the tank that I could see. There was some sediment at the bottom of the tank, but nothing major. Unfortunately the particulate filter was in the tank.... but no longer attached to the outlet, so useless. This is a common occurrence with SD1s. Due to the design of the tank, the only access hole is the sender hole which is too small for an adult hand, and the tank is very deep in this area, so there is no way to reach the filter and reattach it. Stoked, the tank is all good. I wasnt looking forward to paying the $600+freight+GST for one from Rimmers, which would still need to be cleaned and internally coated. The terminals on the sender were all badly corroded, so they got a quick clean up, but I also found the reason for the sender reading 1/4 low.... the float had fuel in it! Not much, but enough it wouldn't be floating on the top anymore. Strangely, there are no signs of any holes or gaps in the seams, so no idea how it got in there. I drilled a tiny hole with the smallest bit that would fit in my drill, and drained the fuel The next day when I was sure it was empty and dry, I used my little soldering iron to melt plastic back over the hole and seal it I did test the sender when it was out, and it seemed to read accurately based on where I positioned the arm, except no matter what, it wouldn't go over 3/4. I suspect an issue with the fuel gauge or maybe the sender itself, but as long as the rest of the scale is accurate now, I'm not bothered. With the terminals cleaned, and the float emptied and sealed, I refit the sender with a new gasket ring. I used copious amounts of red rubber grease to lubricate the seal, so the retaining ring wouldn't catch it. Screwdriver and hammer once again employed to knock the retaining ring clockwise to lock it in place. Back to the fuel pump, which is the main course in this buffet of goodness. Replacing the fuel pump is a pretty straightforward process, I just wish I didn't add another 20L or so to the tank, as the fuel pump is inline under the car and gravity fed from the tank. It lives tucked up in front of the tank, covered by steel plates and in a little rubber/foam housing. It should be bolted to a crossmember that goes across the trans tunnel, but my crossmember was cut off so the stupid exhaust would fit. I had previously noted that the high pressure hose on the outlet of the pump was looking a bit worse for wear, so wanted to do this job anyway, this just sped it up. I purchased some spare 8mm hose for the pressure side, and some new hose for the inlet side, which is low pressure, so doesn't need to be special EFI hose. Since the in tank filter was no good, I wanted to fit an inline filter before the pump. This is also a common mod with SD1s, to try to trap rust before it kills the pump. It may not have been rust that went into my pump, but something chewed it up. This filter may have saved the pump, but oh well. The standard hose from the tank to pump is 12mm ID. Finding a filter on the shelf with an inlet/outlet of 12mm or 1/2" is damn near impossible here (You can order them online, such as the WIX 33299, but I needed it quicker than that), so I had to look for an alternative. I ended up buying 7/16"/11.1mm fuel hose from Repco and picking up a Ryco Z153K filter. It has a 10mm inlet/outlet. To remove the pump I found it easiest to remove the whole crossmember and bracket assembly first, and leave the pump hanging by the hoses. I don't have any photos of this because it's a pain taking photos under the car, and the next step got pretty messy. Something had been living on the bracket I suspect Being gravity fed, as soon as you remove the feed to the pump the fuel tank is going to drain, quickly. I removed the hose from the pump and directed the end into an empty fuel can. I drained the tank until the fuel started to sputter from the hose, as the little baffle sump in the tank filled and drained. This allowed me to remove the hose from tank and fit a piece of new hose that I had plugged with a wheel stud I then removed the outlet hose of the pump from the hard line Moving to the bench it was time to replace the pump and hoses. The outlet hose was worse than expected. It's a miracle it wasn't obviously leaking (although there has always been a strong fuel smell in the vicinity of the fuel pump, but no obvious wetness). Sorry for the average photos. Here is the replacement standard pump, in the housing The only place to fit the pre filter is just before the pump, as the rest of the hose is covered by the brackets with minimal free space Pinched the connections from the old pump and swapped to replacement, with some modification as old pump wasnt original (it's actually a proper Bosch 070, or maybe a "copy") and uses screw terminals not spade terminals the standard one does. Nice new hose (and not the shitty fake R9 hose) I pre-assembled it on the brackets to see how it all fit, but you can't actually fit it to the car like this, you need to do the reverse of removal; hang the pump from its hoses and then fit the brackets Then it was just a case of refitting it all. Once the pump was back in place, I directed the hose in the engine bay (inlet for EFI filter) into a bottle, reconnected the fuel pump connector and turned the key. It took a couple of primes to get all the air out, and fill the pre-filter, but then it shot a nice stream of fuel into the bottle. I did this twice to make sure there was no more glitter or dirt in the lines, and fit the new fuel filter. A quick test to fill and prime the filter, and then proceed to spray pressurised fuel all over the engine..... oops. I replaced all the hose clamps on the fuel filter with proper EFI clamps, as the hoses were still good, but I hadn't got a good seal on one of the clamps. Repositioned and tightened, and she was all sealed up. The replacement pump is nice and quiet, and makes a smoother whirring sound than the old 070, even with the resistor bypass in place. I took Tess for a quick drive to see how she was. I was a little peeved off, the hesitation was still there. I returned home, swapped back to the fuel pump relay, which quieted the pump down further, but it still makes a nice soft whirring sound, but the issue remained, even to the point where stabbing the throttle at idle caused the engine to stall. I tried to restart but it wouldn't immediately start, so I decided to have a quick look at the spark plugs. I removed a plug and sure enough it was as black as night. Very rich and fouled. I whipped out all 8 of the plugs, and they were all the same. I cleaned then all with a wire brush and brake clean, and regapped them from the 0.9 they were (I lowered the gap when fitted at recommendation of others), to 1.1. I figure a bigger gap might help have a bigger spark to blast through the carbon on the plugs. Unfortunately I had a whoopsy removing one, and broke it >_< Thankfully I have spares, so I popped a replacement in I had to shoot out and pick the wife up from the train, so took Tess to see if tweaking the plugs had changed anything. The car started fine with the clean plugs, but still hesitated. I picked her up and just as we got home she asked if I had given it a good blow out. No, not really, so we went the really long way home... with a decent italian tuneup. The car now revs happily and freely, no matter how quick you jab the throttle. Despite taking care in the wet conditions, because traction, I still put the hammer down and blew them cobwebs out. I can't be sure what fixed it exactly, but the fuel pump was not in a happy place, and the spark gap may have been too small. I also suspect one or more injector is weeping/leaking, so that wont be helping. The fuel gauge does read much more accurately now too, which is awesome. The lesson here? If you don't have a pre-pump filter, and your fuel pump is already sad, don't run your 30+ year old car low on fuel. It might just be the straw that breaks everything. As a side note, don't worry, Le Mini Snicket is still here. I moved it outside the other day and then it proceeded to rain. This was a good test of the new window seals i fitted, as the interior was dry, with no signs of leaks. Success. I'm just getting the money together to take it for the registration inspection, and then we will see where we are.
  24. The MS manual explains it pretty good http://www.useasydocs.com/details/numsquirts.htm Previously you had all 4 injectors firing at the same time, now it should be firing in pairs of cylinders. Off the top of my head i think you should generally be running 2 squirts alternating
  25. Blegh, bugger that. At least the Mini had an actual cooling system filling point, google is useless with the Megane. Just said to fill the expansion tank. Maybe see if anything comes out of the bleed points?
