Popular Post ThePog Posted March 1, 2020 Author Popular Post Share Posted March 1, 2020 The swapmeet was a success in that I ended up with $500 burning a hole in my pocket. This was more about the quantity of shit moved, rather than selling things for what they are actually worth, but the result was what I wanted. So I went and bought some bends. When the manifold came apart it was clearly leaking in a couple of places, so this is a good time to rectify things. First i bolted the flanges on to see if all was orderly in that department, which it was. 1.75" primaries I ended up making a mandrel to smash into the end of the tubes to get the shape more or less in the right squish to fit in the flange Then pointed them to the correct turbo inlet and tacked into the flange; Then the other 3; Then weld the inside of the hole. I left 5mm of space for the weld to go Then used a die grinder to clean things up all nice and purty I cut up the wee adaptor plate that was part of the previous install to give me a turbo inlet with pre made 2" pipe inlets. It already had the EGT Sensor fitting and pre squished pipe. This got held in place with a welded bar while everything was in place on the engine. I then bolted it all onto my spare head for checksies and to keep the flanges flat. This shit just got fudged till it worked Then much weldy weldy and some cleanup of the biggest dags. Then I bolted it on after applying a bit of VHT to hide much uglyness. Hopefully sorted and when I test it there will be a few less squealy/ticking/chugging noises. I call the design a 'hybrid log'. The theory behind it is to direct as much of the exhaust as possible into the turbo without any consideration for pulse sequencing, equal length runners and/or scavenging etc at all. I count the result as an almost perfect success in this respect. 30 Quote Link to comment Share on other sites More sharing options...

I thought I would look up what a zephyr manifold looks like, and yes it is definitely no worse than that. In fact I believe mine to be superior in a number of ways. I suspect I would have been an engineering visionary had I worked in the British car industry in it's heyday, all I would need to do would be to sit in the design meetings and suggest that maybe we shouldn't do this in the most retarded way possible. 2 4 Quote Link to comment Share on other sites More sharing options...
yetchh Posted March 1, 2020 Share Posted March 1, 2020 Anecdotally I read somewhere that they made the exhaust manifold like that so it didn't have too much power for the time.. If that's true my guess would be the skinny little 165/13s rolled over and died when power was applied out of corners..... 1 1 Quote Link to comment Share on other sites More sharing options...
Popular Post ThePog Posted March 15, 2020 Author Popular Post Share Posted March 15, 2020 Been tidying up the last things, the list is quite short now. Just boost and vac gauges to fit, which I ordered off aliX a month ago and are not very likely to turn up anytime soon I guess. Give me what you have lying around right now you selfish bitch. Ok. Put some rubbery stuff up in the front wheel arches for some splashy splashy protection. Pretty much the same on the other side. Then I got a Hilux airbox from the wreckers and hacked it about so it could act as the ventilation inlet filter. Fucking hard to mig 0.4mm steel but I have the hole chasing skillz. Seems to do the job ok; Also it has mudflaps in the back now. Also I fitted the CB that was in the bus into it, 10-4 big buddy. 28 Quote Link to comment Share on other sites More sharing options...

ThePog Posted March 24, 2020 Author Share Posted March 24, 2020 I've been chasing a power steering pump leak which was the result of a bodge to the inlet I had done, I made a very beautiful replacement. Then the ps pump appeared to shit itself immediately and I am a bit puzzled. I have stripped the pump down which seemed to be ok, some minor wear, and replaced the fluid when I put it all back together. Now it works but only when the revs are up, there is almost no assist when at idle. It is a bit weird and I kind of want to check the actual pressures but this might be a mission. Any ideas on what to check? I sort of remember a tech article on here about honing that shit up but I can't find it now. Also it stopped charging, fucking thing is manufacturing things for me to do during lockdown... 1 Quote Link to comment Share on other sites More sharing options...

I don't have a stone big enough unfortunately, but I just found another pump at the wreckers. If I can sort this I will be able to carry on testing over the next week's.. 1 Quote Link to comment Share on other sites More sharing options...
Transom Posted March 24, 2020 Share Posted March 24, 2020 Sheet of glass and fine sandpaper ? Or just sheet of glass and grinding paste ? 1 Quote Link to comment Share on other sites More sharing options...

I have some 1200 and 1600 grit paper, if I get stuck I'm sure I can use those. I'll see how the new pump goes. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted March 25, 2020 Share Posted March 25, 2020 No charge and weak power steer, not something as simple as drive belt slippage? 1 Quote Link to comment Share on other sites More sharing options...
ThePog Posted March 25, 2020 Author Share Posted March 25, 2020 1 hour ago, mjrstar said: No charge and weak power steer, not something as simple as drive belt slippage? Na I've been through all that, it had new belts anyway, checked those, degreased the pulleys in case they had got oil on there. Also I just checked the alternator output at the fuse box and there is nothing. I might have knocked something loose when I last had the engine cover off, so I will check that next. The new pump spins way more freely than the old, I'll get it in there in the next couple of days. It also appears to be running out of fuel around 3000rpm, I had the cover off to turn up the fuel, that test run got me 3600 revs and a bit more punch, but that run was also when the pump lost its shit.

ThePog Posted March 27, 2020 Author Share Posted March 27, 2020 The new power steering pump solved that issue, all is well now. I then stripped the alternator down, it is in pretty poor condition, it was full of oily gunk that had been pushed through from the vac pump. The brushes were toast, pretty obvious that was the issue. If I can find some brushes it will do for a wee while, but this is proving difficult. I may have to dismantle some power tools and whittle whatever brushes I find to suit... 4 Quote Link to comment Share on other sites More sharing options...
Popular Post ThePog Posted March 29, 2020 Author Popular Post Share Posted March 29, 2020 So yea, no luck sourcing brushes, just as well I have a lot of useless shit lying around; Makita 9" grinder brush Vs worn Safari After a bit of loving with the file Into the carrier I cleaned up the slip rings in the lathe, you can see why I won't bother too much with this alternator, that ugly bit of shaft is where the seal from the vac pump is supposed to do its work. The whole alternator was full of oily shite, this is the culprit I imagine. I chucked it all back together and got charging voltage no problem at all, a triumph for bodgy cunts everywhere. 17 2 Quote Link to comment Share on other sites More sharing options...
ThePog Posted March 29, 2020 Author Share Posted March 29, 2020 Ha, after all that it turns out the reg is fucked, the old girl pumps out 34v when spun up, probably unsuitable for battery charging. Ah well. Also the fucking power steering still isn't playing the game, it's fine for a wee bit but then loses it's shit. I am working on the theory that the pressure relief valve is sticking open. Does anyone know if the valve is in the steering box or the pump? Just as well I have time to look at this shit, but it's getting tiresome... 1 1 Quote Link to comment Share on other sites More sharing options...
CUL8R Posted March 30, 2020 Share Posted March 30, 2020 Not too much help to you, but the one in my Saginaw box, was about the size of a hearing aid battery, on the Inlet side. I got it out with a pick/screwdriver. My power steer guy bored the pump out, and removed the relief valve - as mine was stopping flow going in - due to the AN fitting crushing it effectively closed. He mentioned they're more for when the box is higher up, to stop flow going back. Bit I figure its only a problem if the car isn't running.. Make sure you bleed the box with no load, full lock to lock (best to remove the pitman arm) - as full lock on the steering system may not be full lock on the box itself..

Mof Posted March 30, 2020 Share Posted March 30, 2020 How exactly is it losing its shit? Quote Link to comment Share on other sites More sharing options...
ThePog Posted March 30, 2020 Author Share Posted March 30, 2020 I dick around with it, fill it up, bleed it. Everything seems tickety boo then when I drive it, it drops to nothing. Sometimes increasing the revs makes it work again, but only at higher revs. I checked the relief valve today, it moves freely, plus it was the same situation with the old pump, I wasn't sure if the valve was in the pump or the box, it's in the pump so that's not it. The problems started when I made the new inlet from the remote reservoir, maybe it is restricting the flow somehow, although I took some care to make sure it was as open as possible. Before this it was absolutely fine, although leaky. Today I also decided to eliminate this as a possible problem and re jigged everything to work with the original reservoir that sits on top of the pump. This just means I have to make a hatch to access the filler from behind the drivers seat. This is nearly all done, I will check it tomorrow, if it's still bollocks then there must be a problem with the steering box... Quote Link to comment Share on other sites More sharing options...
Mof Posted March 30, 2020 Share Posted March 30, 2020 When it stops working, Can you hear a growl noise when working the steering? Does the steering get jumpy/ notchy? Quote Link to comment Share on other sites More sharing options...
