this just started last week, oil level seems to still be ok, compression check all cylinders 198-200 psi, 0% cylinder leakage in all cylinders. its just that second plug on the drivers side, theres oil around the electrode. all other plugs are perfect. it doesnt smoke all the time but always smells like oil is burning from the tailpipes, hard to explain but its def not normal. maybe i have a guide or stem valve seal problem?
