What's Gone Wrong Now?

In recent months my R32 GT-R has barely been run. I had a fuel pump die and took me about 3 months to replace it. I'd drained the fuel and kept it topped up and started a few times a week to idle whilst I needed to fix other things.

Today I started it and drove it down in front of the house (it ran fine) then I put fuel in it and went to start it. When I did, it barely struggled to idle and then smoke started radiating from the hot side around the turbos and dump pipes. I shut the car off straight away.

What am I looking at here? Turbos? Something more sinister?

unlikely something terribly sinister. I get your frustration though. keep driving for a while maybe the smoke will clear; possible carbon buildup? while its running can you see smoke escaping from anywhere? did you leave a tool on top of the motor?

As soon as I fired it up after adding fresh fuel, the motor idles at about 400-500rpm and a dark smoke radiates from the area the turbochargers are located. The longer it ran, the more smoke rose out of the engine bay. The engine did rev freely whilst the throttle was open but returned to a rough idle. As soon as I realised the possible seriousness of the situation, I cut the engine.

The rough idle could be a vacuum line, intercooler pipe or anything. What I'm most concerned about is the smoke, also the fact that nothing changed from it running perfectly 20 minutes earlier other than 15L of fresh fuel again.

Cheers.

did you use an crc product or wd40 or silicon's or anything around the intake/exhaust manifold...this can take a while to burn off and create's smoke at the same time....the fact its not idling properly is a bit of a worry...check your intake piping for improper connections and or splits in piping etc.

      Steps to DIY sanding car back ready for respray....

      Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.

      Hi, Got the membership renewal email but haven't acted yet.  I need to change my address first. So if somebody can email me so I can change it that would be good.
