The Oil pump realy shouldn't be the issue,It sits way to low in the block from the cam. It's not locking up on the crank gear is it????.
just a Question I have What is the reason for removing the cam to start with? a Up Grade? did something Brake?? Have you tried to rotate The cam as you remove it to see what happens.??
I have never had or heard of a issue as you are having to remove it.
God doesn't like ugly.
