Hello guys,

I've unfortunately been bogged down with what seems to have been a bad buy on this vehicle last year.

I've been plagued with bad blue smoke from the exhaust and thankfully I did have a Lubrico warranty to help me out a bit.

Things done so far:
Valve Seals (all 32)
2 new turbos
Oil separators
Upper and lower EGR valves/Hoses.

I used to get a puff of smoke right when I started the car in the AM but after all of the items above that no longer happens.

My issue now is only blue smoke when engine is hot and left idling for a few min.

Thoughts?

Did you do a compressiontest? could be the piston rings i think correct me if im wrong.

Thanks Speedy38,

Yes, I am going to have Leakdown test performed on Wednesday. This should catch any pressure loss, hoping they are ok bc that will be another big job.

...Hoping to get some answers!

You can try GM top end cleaner. Have to remove the plugs and put a few spoonfuls in then let it sit overnight. Afterwards crank the engine so it spits it all out. Can help with carbon deposits and sticky rings if that's the case.

Unfortunately it’s probably a couple of bad cylinders if your still burnin after replacing stems/turbos (assuming they’re done correctly). It seems to be common to score a couple cylinders if you’re burning a lot of oil. The huge amounts of carbon build up on the cylinders damages the walls and rings.
