smoking on over run
Turbo Mini Forums

There is a fair bit there but what I really cant get my head round is the compressor housing is spotless!

ould easily still be the turbine side oil seals. had it happen myself on a few occations before i realised my turbo oil driain (and breather) was less than satisfactory. each time it smoked on over run and occationally at idle but the compressor outet was always clear. replacing the turbo always cured it.

either exhaust side of turbo or the dreaded piston ring lands have failed like mine did, what pistons are you running

always looking for them bigger bunches of bannanas

PLEASE dont even put that thought in my mind Richard, I think they are the mega's from morespeed. will fit the new turbo next weekend, will soon see. The crank pully has thrown a shit fit too, its just one think after another.......
Shane

if the ring lands are gone shouldnt it show up on a compression/leakdown test?

Ive not done a compression test on the engine yet, will do it tomorrow, just out of curiousity.

when I think about this, I'm not sure why you should be nervous about this, in the back of my head I'm not sure that any turbo mini I had, hadn't made this less or more when the breather are disconnected from vaccum .
I would try to connect it back, it will help turbo seal as when the turbo is of boost the vaccum help to "suck" oil from passing seals, then past vaccum, your turbo will be on boost, then this prevent oil to escape
I would try to connect back first and see if I need to thru my money in this

That does not compute the compressor housing is clean but the coupling pipe is covered in oil!

When we check for oil lreaks in the compressor side of a system there is one check that never fails and should work here.

the tight bend at the top of plenum chamber, check to see if there is any oil smeared around this bend.

Own the day

My money is on turbo seals Exhaust side tbh

Well, have a new turbo ready to fit. But parts I ordered from mini sparwes havent arrived so not going to get it running this weekend, not happy!
Shane.

Mine does the same shane, and im interested to know if yours stops smoking when you replace the turbo seals? Cheers, hope all goes well

More Boost, More FUN!
