Blowing Smoke

[dinosouar]

hi, my r33 skyline is blowing smoke at idle or any rpm and i cant seem to solve the problem. I had the turbo rebuilt thinking that would solve the problem but it still happens. Ive done a compression test and thats all ok. I disconnected breather hoses from engine but still smoke. took of oil dump pipe and ran oil into bucket to make sure wasnt a build up of pressure in turbo while engine is running. motor does not have high oil pressure and flowed 1.5 litres of oil in a minute from turbo oil feed. I am still getting oil leaking from compressor and exhaust side of turbo which must be why engine is blowing smoke but like i said turbo was rebuilt by someone who has a good reputation. can any one give me a idea of what to do as i have no ideas left.

thanks dean

Was it still blowing smoke straight after the turbo rebuild?

What colour is the smoke?

Also i would be taking it back to the guy who did the work or go to another turner and get him to look at it.

yes was blowing smoke straight after but i also tried another second hand turbo and it did the same thing. smoke is white and is not consistent as sometimes its heaps and other times its less. B4 i rebuilt turbo it only blew puffs of white smoke at above 4000 rpm and went away. after rebuild it blows smoke non stop. Is their a place in adelaide sa that tests turbos of the car. thanks dean

Run the car and go round to the exhaust pipe. take a whiff of the smoke. what does it smell like? it shouldnt be fuel smoke as you said it was white. fuel smoke should be black. im thinking you may have water thats being passed through the exhaust pipe. probably a coolant issue. blown head gasket possibly? burnt oil is usually a bluish smoke colour, but you may wanna check out all possibilities. are your intercooler pipes all properly connected?

hi, when i take the intercooler pipe from turbo its got oil in it aswell as when i take exhaust dump pipe off its oily and looks wet even after ive cleaned it out. so smoke must be comming from exhaust wheel of turbo. If turbo has been rebuilt does anyone have an idea of what else could force oil out of both ends of my turbo.

White smoke usually means water, so either you may have a head gasket problem or if possible one of the water lines in the turbos is leaking.

Are you using any water at all? Check all levels.

Also let it idle so the water temp gets up to operating temp and see if you are leaking any water.

Put your hand over the zorst and feel if it is wet. Do that while it is still running and has warmed up.

Let it cool down over night and check your water levels.

If the water levels have changed then it is possible that you may have water leaking into the zorst.

jsut like zardos said, head gasket maybe, or the cooling line for the turbo. That "oil" you mentioned might be the coolant, coolant dont evaporate. but leave it for a while ( especially if it mixes in with shit residue inside the pipes) and it feels kinda oily.
