Oil burning at idle (blue smoke)

Post by Slim on Thu Apr 30, 2015 12:40 am

Hi

Uno Mk2 Turbo

Been getting blue smoke from the exhaust at idle. Normally happens after I have given the turbo a good workout. I believe it's the turbo end seal on the hot side as I can see damp around the core and turbine housing. Spoke to Turbo Technics earlier and they suggested that the crank case pressure may be to high due to blocked breather, in turn causing the turbine end seal to leak. Breather is clear and breathing to catch tank. Compression test showed good even results. Engine was built 6k ago, turbo was fresh then too.

Any input welcome!

Cheers

Sorry, Only happens after I have given the turbo a good workout, pulled up to let cool before i switch off, idling for 30 secs and the smoke starts, smoke continues for 2-5 mins and then stops, won't see it again until I repete.

It was the hot-side turbine seals.
