Cool

check your compression on all cylinders... take compression readings for both "wet" and "dry"... and that will tell you where the prob lies.

gas in oil =

stuck or leaking intake valves, (maybe adjusted just a little to tight on the intake valve clearance)

worn rings

Cool

cold engine:

0.008in/0.20mm COLD for both intake & exhaust.

done 1 cylinder at a time, of course, with each cylinder at TDC at time of adjustment
