Weird issue? New rebuild, Small progress ??

Right as the story goes supra was burning oil pot 1 was flooded with oil, so we began a strip down and took engine out basically. Sent block away to find out pot 1 had been scraped by a ring, got a new block had it honed, now this engine has got new rings, new bearings (acl) new stems the works basically that needed changing, its na-t so its been ran in now done about 1400kms and had a few runs here and there underload. After it been boosted the car turns to idle after 20-30 seconds SOMETIMES it will let out some smoke, but none under acceleration or boost, im kind of lost?? because this smoke comes out and leans off till no smoke, but if your too hold on the revs at 2k for example the car doesnt smoke??

Also it has a stage 4 comp clutch fitted and it makes a squeal when setting off is this normal till its fully bedded in

ANY help will be appreciated cheers Rob

Your turbo is nodgered!

But there isnt any oil in either side of the turbo and all pipes are dry?

Ok, where are your crankcase breathers vented/not vented to?

Well this is what we were thinking, they both had small k and n filters on, right side of engine now is going back to the inlet manifold and the left side is on a pipe going to atmosphere

Anybody got any more suggestions ideas?, had this happen to them?

That sounds a lot like when my turbo seals went.

How old and what brand is the turbo? Have you popped it of it's exhaust housing to check that the seals are good/there is not a film of oil leaking over the exhaust wheel?

Well i know everyone will say turbo turbo turbo now, its a t61 xs power, done about 10k miles at 7psi, and not actually took the turbo apart as of yet

What colour is the smoke?

Does it smoke on start up?

Perhaps they will say that because the symptoms sound exactly like classic turbo seals? Plus it is a cheap crap turbo, you know this.

no smoke on start up, if i drive it and change before any boost it wont smoke on idle, but if i 5k or 6k run down the road return to idle it will eventually smoke after 20-30 seconds, but then if i hold revs at 2k to clear the smoke it wont smoke on idle, and yeh i know the turbo is crap haha

What colour is the smoke?

kind of grey/blue but the car isnt using much oil i must of topped up 30ml since friday and its been constantly on the road and i presume being new parts internally it would use a bit of oil (i check this everytime i get into it)

Right so today we took downpipe and inlet etc off the turbo to see for oil dry as a bone both side (double checking things) then we ran the car without either connected to see if there was any weeps, none also there is slight shaft play in the turbo possibly the issue, car ran for 30 mins got warm revved idled no smoke?, then rebuilt car went for drive put load on car still no smoke, is it possible that putting the breathers back to how they are stock solved this smokey issue, my other thought was the mechanic dropped my oil wonder if he had it a little bit high on the dip?
