The seals on the tubes need to be replaced. The #4 exhaust one is leaking right in front of me and the engine hasn't been run for a year. All my manuals say don't use pliers so how are they removed? Rocker arms, retaining wire and push rods are out. It wiggles a smidge but I can't get a real grip on them and they seem to be stuck to the block.
This is my first time replacing the seals so any other recommendations are appreciated. Right now I'm just trying to get the left side done
