R32 Gtr Turbos Smoking!

[evilmidgetdude]

Hey guys im still having heaps of issues with my R32 GTR. Anyway first it had a stalling problem and the other day I was driving and as usual it stalled, few days later I started her up and she died straight away, when I finally got her started she was idling and revving really rough and won't rev over 3k and blows a shitload of black smoke and I've just noticed that there white smoke coming from the turbo's side.

Would my turbo's be blown? Or motor maybe?

Black smoke = running rich, which will happen a bit because the standard tune is quite rich, especially if you have wound the boost up. It will also run very rich if you have an air leak and youre boosting (or at least the turbos are attempting to boost). You wont make much power if you have any decent sized air leak. Usually this sort of stuff is not that serious.

White/blue smoke = oil burning, this is usually more serious. Can be from oil leaking past turbo seals, or past valve stem seals or past piston rings.

So, first couple of things;

- Check engine oil level

- Look for air leaks. Could be a split intercooler hose (one of mine just did this) or loose connection. Probably not a hose coming off because you would typically get a bit of a pop when it comes off, but still check for it.

- If you make no boost at all (ie it goes from vacuum to 0 but not past it) you have an air leak or blown turbo. Its pretty much always the rear turbo that blows. If the turbo has blown you will see ceramic turbine bits trapped in front of the cat, so you could drop it to check for that. It just looks like bits of rock.

- After that, a compression test may be worthwhile

I just checked and the intercooler pipe did pop off so I put it back on and it's still doing the same thing and won't rev over 1k now :S
