So, my engine is still smoking periodically, and it is definitely burning oil. I've run out of ideas. Any ideas are appreciated

This is what I've done/checked.

1. Compression good on all cylinders
2. Turbo is dry on turbine side
3. Head gasket changed
4. Valve seals changed.

Should I change the PCV valve, or would that be a waste of time, since it is smoking quite a bit.

 

valve stem seals? or rings...that sucks dude

 

i just finished replacing the valve seals, and perfect dry compression would suggest good piston rings (plus I just looked into my block when my head was removed, everything looked fine), any other ideas ?

 

If it smokes out the breather on decell probably the ringlands.... What do your A/FS look like??? Have you done a leakdown test??? How do your plugs look??? What about the compressor side of the snail/inside charge pipes.......

 

Just drove it today, couldn't boost, and heard rickety sounds from the turbo. It's the turbo, just didn't notice it before since it was still building boost.

Weird though, since it was rebuilt just 15K miles ago. Must have been something with the oil pressure.
