I got a borescope off of Amazon and it was an aluminum washer in #4 cylinder. Just a little too big to come out through the spark plug hole.
I'm trying to loosen the big nut on the cam. I have the special tools for a 1979, and through trial and error I found that on the claws-foot (or crowsfoot what ever it is called) you have to mount you wrench on a 90% angle or else it slips off the nut real easy. BUT, I can't seem to break it loose, are there any tricks to this ?
There is a deep cold chisel mark on the nut, that is used to set it tight when installed, No? Should I be doing anything else to counter it?
