Ghostchips Posted March 16, 2019 Share Posted March 16, 2019 Weld. Machine for whatever wheel nuts suit the car, or whatever is available. Plugs on wheel stud holes sounds kind of dumb. Quote Link to comment Share on other sites More sharing options...
Nominal Posted March 17, 2019 Share Posted March 17, 2019 Why is my Nissan doing this? VQ30De. Don't want to spend much $ or effort, but it would be easier to sell if it idled OK. I did take apart the intake piping and clean the throttle and IACV with carb clean. Didn't help. Starts as soon as the car is started (even from cold).

tortron Posted March 17, 2019 Share Posted March 17, 2019 typically it could be the TB or IAC. if you have cleaned them it may need a new IAC also check vac hoses, a leaking vac booster can cause this. also a flogged out MAF Quote Link to comment Share on other sites More sharing options...

Yowzer Posted March 17, 2019 Share Posted March 17, 2019 ^ Yup start with that. Smoke test if you can, spray brakleen around if you can't. Faulty PCV valves can also do funny things at idle too, pays to whip a new one in while you're at it. Quote Link to comment Share on other sites More sharing options...

Where is the PCV on this thing? Quote Link to comment Share on other sites More sharing options...
kyteler Posted March 17, 2019 Share Posted March 17, 2019 What about the vacuum line to the booster? Quote Link to comment Share on other sites More sharing options...

I connected a vac guage to the port, cycles 18-20 (inHg I guess) right in the green zone. I'll pull the IAC assembly off later and take a pic of it. 1 Quote Link to comment Share on other sites More sharing options...
Sambo Posted March 29, 2019 Share Posted March 29, 2019 I feel dumb asking this. I bought a few 5/16" x 1/8 BSP brass fittings the other day, but for the life of me I can't figure out what tap I need to buy. I'm sure I'm over thinking it, but nothing actually says 5/16" x 1/8 BSP. Can someone tell me what I need to look for? Quote Link to comment Share on other sites More sharing options...
Mof Posted March 29, 2019 Share Posted March 29, 2019 5/16 must be one end, and 1/8 the other? 1 Quote Link to comment Share on other sites More sharing options...
Sambo Posted March 29, 2019 Share Posted March 29, 2019 That sounds like a big taper to me, but I'll have a look when I get home from work! Edit: It does actually make sense. I was getting all crossed up because I thought 1/8 must be a BSP thread pitch or something. Why isn't everything metric? Quote Link to comment Share on other sites More sharing options...

datlow Posted March 29, 2019 Share Posted March 29, 2019 What sort of fittings I assume 5/16 is a hose size? Then 1/8bsp is the thread size so just need a 1/8bsp or maybe 1/8bspt (tapper so it has something to tighten up into?) 1 Quote Link to comment Share on other sites More sharing options...
ajg193 Posted March 29, 2019 Share Posted March 29, 2019 A uni-t ut210e just showed up in the mail today. It was $49.46 from Aliexpress and took only 9 days to arrive. The best bit about it is that it reads up to 100A DC using the clamp. This should be really handy for troubleshooting stuff on a car. No more breaking the circuits or removing the fuses, just clamp over. The 2A setting seems to be accurate to about 2%. It also does beeping continuity tests so that will also be nice. The whole thing, including leads (in supplied bag) is small enough to put into a tool roll and keep it in your car. Not a bad item. 5 Quote Link to comment Share on other sites More sharing options...

NickJ Posted March 31, 2019 Share Posted March 31, 2019 Not sure if we have a tyre tech thread? Swapped diffs out on the Datsun today and cut my hand on the tyre, glad I noticed it! Well the tyres are pretty old so no real loss. As for replacements, whats a good 205/60/13? Seems to be heaps of budget options, anything sporty other than semi-slicks? On that side, anyone run semi-slick tyres on a weekend car, do they last long? Bear in mind it's a Datsun and driving in the rain is a serious corrosion hazard!
