Smoke from the valve covers is a sign of blow by, or oil temperature problems. Blow by will actually blow the oil ring out against the cylinder walls, and stop oil from getting by. With good quality modern rings, odds are your problem is the hone, or what you're doing to assemble the engine.


Call Keith or Kevin at Total Seal.


The proper way to test cylinder seal is with a blow by meter on the dyno, with a Dwyer guage, there's no real substitute There's a video on youtube, by Lake Speed Jr.
