Occasional White Smoke Under Boost

[CRoNic...]

This is a pretty strange issue.

My R32 GTR, under very random occasions (about once every 2 months) when I accelerate and hit boost, I'll have a cloud of white smoke behind me. If I let off the accelerator, obviously it goes away. If I do the same again straight after, there's no smoke what-so-ever and it won't happen for another few weeks or even months.

Now, this has only happened to me twice now but both times it's been raining and very cold outside. It's obviously not the normal condensation in the exhaust, but would it be some sort of condensation somewhere else? I'm only taking a random guess, though. It's not burning oil, and there's no howling sounds from the turbo's or any of the normal symptoms of a turbo on it's way out. When this happens, I don't loose any acceleration either and I don't hear any other weird sounds.

Also, when this happens, the car's been driven for around 5 - 10 minutes so it's hit/close to normal operating temp.

Any ideas?! I've had the 100,000k service + dyno tune. I do have a rubbish exhaust though (loose baffles inside the cat) which is getting replaced soon (sounds like a beer can rattling when I'm drivin) but I doubt this would have anything to do with it.

I'm still running the standard turbo's.

Any help would be appreciated!

Cheers

Hey Chronic

Im no professional but white smoke is usually something to do with oil being burnt somewhere in the exhaust region. This has happened to a few friends of mine but they were blowing white smoke a bit more than you and the culprit was oil.

Also my cat is stuffed at the moment to and sometimes it backfires and stinks when i give it a bit but i dont know whether this could be causing smoke.

I would just have a good look around your exhaust manifold/turbo for any leaks for now

could be wrong but turbo seals?
