I DID see spark jumping, replaced the engine ground wire, cleaned up everything real good. Still have noise, wondering if the cylinder not firing caused other damage? There is no way in my mind that any sort of internal issue is going to cause spark to jump.

Also why just that hole?

It DOES sound like its up high though f#ck i hate stuff like this…
I ran it with the vc off and everything looks right. Pulled the rockers off, they are fine pushrods don't look beat up.
I did not look at valve springs…
