I have my intake manifold off to change the gaskets and paint it. While I'm at it, I want to change the upper and lower o-rings for the oil return tube (a.k.a. bitch tube). The upper is fairly obvious, but how do I pull the tube out to change the lower o-ring? It seems in there pretty firm. Should I just grab hold of it and pull it straight up out of the block, or is there a thread so I should be twisting? I figured I'd ask before I start applying too much force to it and break something.
thanks!
thanks!
