Valve Hitting Spark Plug at Wade Grimm blog

Valve Hitting Spark Plug. If you're lucky, the rising piston and descending valves will hit the spark plug. If it's a new build with a big high lift cam and/or popup pistons it would. The only thing that could make a valve hit a piston is cam timing out of whack. No, valves would be bent from impact with the piston. Set to tdc and check valve clearance, repeat for. If you want, regap them and reinstall them, then turn the crank by hand clockwise and see if it gets stuck tdc. I'd want to take a look at the valves and see if a pair of collets did a comealoose or if a valve is stuck open. So of course the valves need to be replaced. I can't imagine pistons hitting the spark plugs. You can see the small area in the periphery of the intake valves where they hit the piston, the carbon buildup is rubbed off there. Also on the piston surface, there is just an ever so slight etching in these matching areas. You might want to pull the. This will immediately destroy the valves and seize. Very unlikely it's a valvetrain related problem, like bent valves causing the air to leak from the cylinder.
