Turbo Smoky

[nuR.spec]

ive got an r32 skyline which i imported recently. It was a non turbo so i done the turbo conversion on it with an engine which had been sitting for a while. Now the problem is that when you give it to it and back off the excelerator a big cloud of blue smoke is really noticeable throught the back glass. It does it sometimes so i changed the turbo finking it was the oil seal, but its stilll doing it.

DOes anyone no wtf is going on coz its really frustrating.....

sounds like valve guide seals. i had a nissan exa turbo that had this same problem. also if i was driving down a hill and lifted off the acclerator i would see the big cloud of smoke in the rearview mirror.

does it always happen only on gearchange? assuming manual gearbox this would suggest bov is incorrect operating or failed or leaking. perhaps its got a busted seal or is dead or is pluming into the wrong spot or something wierd? do you have any oil leaking from any of the intake parts, like throttlebody area, boost controller valves? intercooler connecting silicon joiners?

well we i done the turbo change i noticed oil traces in the cooler piping also there seems to be oil residue seeping out of the coolers fins but it doesnt always do it, someone told me it could be the PCV valve whatever the hell that is
