SBC Oil Pressure Problem
I am helping a friend build a 350, nothing really special. We had it machined, new rings, bearings, gaskets, pistons, etc..... We went to prime the pump with a drill and got it to 50 PSI. The problem was that there was no oil getting to the top end. We pulled the pump, checked for missing plugs, and checked the sump, but nothing. It will read 50 PSI on the gauge, but it won't oil the top end.
The only thing that we did find, is that when we would use a drill, oil would come pouring out from the hole in the back that directly faces the distributor shaft. It is the same hole that you put a plug in at the back of the engine (the 3 above the cam soft plug.
Any help would be greatly appreciated. Thanks

I might suggest you rotate the crankshaft 90 degrees at a time as you prime the system. This allows Hyd. lifters and all pages to fill. I had the drill reversed 1 time making myself just shake my head.Jeff C.

Ok gang. It's been awhile. With everything that was going on taking care of my mom's affairs and making a few needed mods to the Healey, it was June before anything really got rolling on this...
