well, it had plenty of pressure before when i spun it with the drill.
jim, what do you mean behind the cam? i looked at another block i have laying around and only saw two on the front and two on the back. i will call you tommorow if i have time, maybe at lunch.
I have never had a problem with it when spinning for presure or prelube. Do you have the right plugs in it ??? There are flat ones and there are tapered ones. Sorry the ones I am talking about are on the back side.
