Does it control how oil is sent to lifter gallaries?

 

The place on the housing near the bottom where it has what looks like 2 rings cast into it, goes right through the front-to-back passage that feeds oil to the right bank lifters. Without the dist there is a massive internal pressurized oil leak from that passage being incomplete.

 

And if you prime the oil pump without having those rings in place, not all of the engine will get pre-oiled.

 

...Kinda like this:

 

Well figured it out. Dont buy autozone parts. A cheap autozone distributer could have ruined my 10,000$ motor. They must have remaned that thing so much that there was no seal there. causing the engine to get no oil to the top end. Popped a different one out of my truck in it and damn if oil didnt start flowing through the pushrods.
