Hi,

 

Quiack question, blue smoke on start up and over run, what can cause this turbo seals maybe?

 

And is it a engine out job to get the turbos off?

 

cheers Mark

I have the same problem except only on over run, if i dip the clutch when slowing down no smoke at all, its fine from cold aswell, only ever when i back off the throttle, even just sensible driving

Smoke on over-run will proberbly be piston ring wear, had this on my 300. If you let the engine naturally run down from, say, 5000 rpm to 1500 rpm and the old smoke bellows from the zorts at approx 3500-2500 prm, then piston rings for sure. Sorry dude, rebuild time. Contact "jimmer" on here, he rebuilt my zed, top bloke for it.
