have i broke my turbo too ?

[ceedubya]

after frying my clutch a few weeks ago my car is now burning oil on prolonged tickover (lots of blue/oil smoke)

the turbo is only around 2k old since having a new shaft fitted along with seals running full boost ( td05/18g)

plugs are a nice biscuit colour, no oil in the turbo intake side, small deposit of oil in the boost pipes ?

the car is still running and boosting fine on full boost with no smoke except tickover

the 2k miles was fun but now its a pain in the hoop with things going tits up

I would hazard a guess at valve stem seals. If it's only on tickover then the turbo shouldn't be working.

Mine was valve stem seals. Smoked after a few mins at idle.
Compression test should give a better idea

Not having much luck ATM are you, Chris..

that sounds like mine is it much of a job to change them

only bad luck at the mo, the n249 resistor i got of ya works a treat tho cheers

Good stuff

depends what they find.. but it wont be cheap

 

[ceedubya]

just gonna have to smoke for a while then

was out "testing" today and no smoke using full boost thru the gears and only the odd puff coming down thru gears ?

i will take it to bits to fix both problems when its no fun or shamefully smoking

the derv boys have smoke.. join em.. its no disgrace whilst dissapearing into the distance.

its no fun tho when you cannot see them disapear

is it much of a job to change the valve stem oil seals ???

If it was valve stem oil seals your plugs would be black.

the plugs were a perfect biscuit colour

have had a few boost pipes off and they have a normal thin film of oil, no worse than before it started to smoke

 

[ceedubya]

i am starting to think that my turbo could be leaking oil direct into exhaust system and not thru engine ???

everything i have checked on engine side looks normal and isnt showing any signs of burning oil

any other ideas anyone

 

[PhilW]

Restrictor fitted on the turbo?

 

[Backdraft]

Is there a leaky gasket on the mani to turbo or the turbo to dp?

then it would blow not kick out smoke on start up.

no blowing on start up or when cold, deffo think its putting oil direct into exhaust system and missing engine completely since i have checked plugs after a session

So it's using oil only under high vacuum. Your turbo should have a restrictor already built into the CHRA.

You could pull off the downpipe and see if the turbine has signs of oil on it, though I'm not sure you would spot it. Also if oil is only running through the engine periodically I don't think it would oil the plugs either.

Have you thought about checking the breather system one way valves. You could be sucking straight from the crankcase into the inlet.

cheers for ya help

its at its worse on prolonged tickover and i dont see any smoke while driving but people following say it ocasionally puffs a bit out when i am coming down thru the gears.

the breather system is factory at the mo, i have a breather tank ready to fit asap

With the correct workshop equipment they can be done without removing the head. But most dont have this equipment, so cylinder head removal will probably be required.
