LANCER Serious Thumper Alliance Member Offline Savage Beast Performance Parts Posts: 10661 Oklahoma Gender:	Smoking Issue 12/06/09 at 16:53:56 Issue: Engine is running and blowing blue smoke out the exhaust. I have replaced valve stem seals ... still blowing blue smoke. Prior to disassembly there was no problem with oil getting past rings. Piston, rings and cylinder are good. What else could cause oil to get into the combustion chamber ?

I know I remember installing them and spacing the ring gaps around the piston; but did I remove them later and forget to reinstall when rechecking the cylinder ? I am second guessing myself now; crazy eh ?

How badly is it smoking? light? heavy? Did you hone the bore before reassembly? Reuse old rings? need more info. A fresh engine will sometimes smoke until everything 'reseats'. Some assembly lubes will cause rings to seat slower. The smoke would be really heavy if you left the oil rings out.

Piston, rings and cylinder bore are untouched and are as they were before, when it was running just fine.

I sometimes second guess myself after buttoning up. Best thing to do is look for the rings. If you can't find them, they should be on the piston.

Just idle or running about? On initial startup, it was billowing like before, but did decrease after a bit. When running up and down the dirt road above the driveway it is smoking like an old 2-stroke.
