My cossie is starting to blow a little blue smoke out when on full boost mainly in the lower gears any ideas what could be at fault?
also my oil reading on the dash is around the middle mark on tick over but lately when ive been stuck in traffic it is starting to go a bit low can any one give me any advise

cahzz

can you give a better description of when your getting the smoke, so youve said at full boost in the lower gears, what boost are you running? do you see any smoke on idle or on the overrun? are you seeing most smoke while boost is building or when max boost is reached?

maybe your turbo seals are letting alittle oil past causing some burning, pull off the induction hose to the front of the turbo is their any movement in the turbine, side to side in and out? sorry for all the questions just trying to help you sort this asap

i remember when mine smoked alittle and on further inspection the oil was way over the max, i replaced with fresh oil at the correct level and it was fine.

I can just see the smoke in my mirror when the car is around something like 5000rpm its stage 3 running 18psi and its when the cars actually boosting

turbo

wouldnt worry about the lower oil pressure at idke when hot, its just wheere the oil has thinned out so much, presumably you are running correct grade?? ie 15/50 or 15/60 etc

Cheers damo fook me i was thinking piston rings engine rebuild all of that im using 15/50 so ya probs right

Damo V

that is the millage and its been hpi'd and has the mot's to back it up

Thn turbo failure most probably. Does it let out puff of smoke when changing gear?

Gary F

iTrader: (1)

No not when changing gear just when the turbos fully boosting the turbos only about 3yr old

Azrael

That's pretty strange, usually turbos only smoke at full boost when theyt are completly knackered.

Idle? off boost all right too? Cold start? Warm start?


It may be breather problem too. What setup are you running?

Gary F

iTrader: (1)

I only get the smoke when the turbo is fully boosting thats it none on start up or when i change gear or any thing and the car still feels really strong its stage 3

Azrael

milkmanif you can actually see it in rear view mirror it's big issue. I wouldn't drive it like that. I would say 99% it's turbo or breather system.

Ok cheers Azreal its getting checked on tuesday so fingers crossed i wont get my pants pulled down

Azrael

Fingers crossed for you....

Damo V

Strange 27k car having had a new turbo... at what? 18k miles??

Azrael

Probably woud require some cold start full boost runs and then hot shut-offs. Still unusuall.

I've got the bill here that says was suggested new turbo as loosing boost

Azrael

milkman turbo failure rarely comes as boosting problems, usually it starts smoking bvadly, buning oil before any power loss comes

Just what it says on the bill mate, it was long before i owed it

Azrael

TUrbos can die from long lack of use. I only read about it, never seen one die after long time without engine running but it may be the case.
