Hey frank, after i posted earlier i went out to the garage and pour alittle oil down the num 3 cylinder and sure enough it went from 60psi to 65psi and no oil on the plugs so the rules out the valve seal and no water in the oil so its looking like its going to be with the valves maybe a burnt up exhaust valve or seat. I suspected a burnt up exhaust valve since my hydro carbons were barly passing california smog bye 1 at both stages After checking the the primary and secondary ingnition systems they both passed so i'll do a leak down test this weekend to confirm it is indeed something with the valves or something else.
