White Smoke

[skybee 93]

hey guys got a skyline turbo has intercooler and everything needed to give it 368hp at the rears, ill cut to the chase. when i accelerate hard then change gears white/greyish smoke pours out the exhaust, but only when i change gears not while im accelerating or even idleing. the car use to run like a dream then i blew an intercooler pipe and drove around with it busted for about a week (silly i know) i got it fixed but it hasnt run the same since its alot more sluggish now. the power use to be instant now its sluggish till the boost comes in then it picks up. plz help. dont know what to do.

sound to me mate like u done the turbo oil seal?, also could have over spun the turbo wheel damaging the bushes or bearing cartiage. wasn.t the car a pig to drive with out the cooler pipe connected???? white smoke bad= burning oil, dark smoke good= just exces unburnt fuel. what type of turbo and line is it??

yeh i had tape on the busted pipe which just go me round. the turbo is just the standard turbo with a 3inch dump pipe to 3.5 inch exhaust system

Blue smoke is generally more an indicator of burning oil. White smoke can be just condensation. Grey smoke is carbon build up generally. While you were driving it with the pipe busted, you have probably carboned up the exhaust nicely with all the over fueling due to less volume of intake air but the same amount of fuel. If it was the oil seal on the turbo you'd think it would be blowing smoke under acceleration aswell wouldnt you? None of this really explains the lack of performance though. Well besides perhaps stuffed plugs after driving it for that long with the busted pipe and over fuelling? Its all hypothetical but things to check out none the less.

Good luck mate,
