Re: Befuddled with engine problem
Plugs "should" show a problem but not necessarily. Symptoms:
Popping noise through the intake-exhaust valve(s)not opening.
Fluctuating vacuum gauge-intake or exhaust valves not opening.
Hard start (slow crank-exhaust valve(s) not opening to release compression on exhaust stroke)
4,000 miles since rebuild-typical mileage for new flat tappet cam failure.
