Ok so I have been having a long battle with my ego and I need some newbie help. I have a built block just rebuilt my head because I was burning oil and the car was smoking during cruising and wot. I put Kinggly spring and retainers in. Cool shorty like couple days later my plugs kept on fouling out. Looks like oil on it. It gets fouled out to the point that the cylinder doesn't get an spark. Car is still burning or leaking oil. Compression test cam back 140,160,155, 150. Leak down came back all cylinders sealed. No issues.. I'm lost to what to do now. One mechanic says it could be my oil rings. But before I got the head done I didn't have the oil on the spark plugs issue just smoking and burning oil. One of my valve seals was bad so that is why I went with fixing the head. Any ideas.....? Any help is greatly greatly apprciated thanks
