need the cam on top of the engine so we can hear it better.
i kinda already told ya how. ^^^^^^start with a compression test, its easy, remove spark plugs, then install the tester hose in the plug holes one by one. your looking for one to be way lower then the rest. would be the one with the messed up plug is my guess.
you can get a compression tester at most parts stores they do free rental. you just leave a deposit on the tool. ful refund when returned.
