Re: Limp mode problem once hot - 06 C30 T5

Well, threw in the towel and called in reinforcements! I arrange with one of the local dealers to drop the car off yesterday morning for 1 hour of diagnostics. Naturally the car ran perfectly all the way there and they could not find any issues as like me they found no codes. By the end of the day ...

Pick a high quality plug manufacturer and inspect the plugs for any visible damage as well as double checking the gap and make...

Re: SMöR öL: C30 Build

Due to the political landscape, my wife and I decided that it would be better for me to not re-enter the US this year. So the build will have to be paused for at least another season.

Re: Still Smoking after PCV replacement

UPDATE Last week I took the car back and they said they would look at it. Apparently the PCV part they put on was defective and wasn't pulling vacuum like it was supposed to. So they replaced it. Now things are back to how they were before. Still puffing blue smoke on cold starts in the morning. Bu...

Re: Still Smoking after PCV replacement

have them look at the turbo check valve (PCV ball valve new version, diaphragm old version) bare minimum clean it up to make sure that it isn't getting stuck in one position or the other. It sits right in the neck of the turbo inlet.

Re: SMöR öL: C30 Build

sorting out the oil drain, had to grab an ultra low profile oil drain flange as the turbo is now about 2" lower than K16/Stock. Set up fittings on the turbo, less the coolant lines to again verify I'm good on space constraints. All clear.
