Bent Push Rob Saga
I’d go for the simple stuff first.
Pull the vc off the other side and look things over.
On the side you’ve been working on, pull that cover back off.
Turn the engine over to the point where each rocker is all the way closed.
When each is in that position, make sure the rocker isn’t able to flop back and forth between the valve and the pushrod…….. but it should slide fairly easily side to side.
