Replaced intake gasket. Engine performance improved. BUT. Went on a road trip (1100 miles round-trip. 30 miles from arriving home, started to misfire (constant). After compression test (#6 and #4 bad), decided to replace the head gaskets. And what fun it was. Had two bent valves, HEAVY carbon build up on valves. Cleaned and inspected heads for cracks. Installed two new valves, lapped all valves, replaced valve seals. Everythings back together, fired her up, tap. Tap. Tap (when you lightly touch the gas pedal there is also an intermittent knock. Sounds like something is hitting the bottom of the intake. What am I looking at hear, bent push rods? Did the bearings go on the balancer shaft? I feel pretty sure some valve adjusting will clear-up the tapping, but the Knock sounds bad.
have the same problem?
