Engine noise after cam install video inside
alright this noise developed after a week when swapped the heads, cam, intake, pushrods and lifters.
it sounds like a hollow knock to me so maybe a piston is hitting it?

If you didn't flycut, that cam is most definitely hitting your pistons with the 59cc heads you have on there. You probably have barely any exhaust clearance. I bet you smacked a valve when you went WOT and that is the sound of bent valves.

well i never drove the car at that, just fired it up a few times and one day that started happening. it never spun past 3k although i can also be wrong about the chambers but if its a bent valve you say i'll take it to a shop since i'm tired of working on it and i cant fly cut it myself.
i was told there is a possiblity of it being a stuck lifter, i'm going to get a stethiscope tomorrow and pinpoint it
