So I pulled the distributer and tried to prime the pump with the drill. No oil pressure. Note what the bronze gear looked like.

so I drained the new oil and pulled the oil pump It is a new muscle motors unit. Not a milidon (I forgot that I got this one recently, It was internal before) The valve slides in and out for the first half easily but gets jammed going all the way in. It needs to be forced to open and close completely. It got be a bit of casting that the valve is getting stuck on Not the wear on the housing and the pump I am not sure if the pump could not turn of if it wa sthe valve of what series on events transpired.

Well you can try reaming the by pass hole to free it up... also get a new intermediate shaft(which you already know)... how long was that shaft in there... I cant see the wear on the pump and housing very well but how deep is it in the housing... I would believe your issue is the by pass not seating

You know those oil pump cover bolts only torque to 25-30#..
They could be over torqued and binding the shaft.. You should be able to turn the pump when torqued, with your fingers using a priming shaft.
Also, put a tiny bit of white grease in the pump when re-assembling. It will help prime the system.

After seeing that now is the time to pull the engine, fix all your issues, clean all the parts, mic and measure, do all the needed machine work, clean all the parts again, and install new rings, bearings, pump, oil pump drive and all other new parts that will be needed.

Mike. I bought the engine used. I don't know how many miles are on it. I bought it to build for the procharger There isn't very much where on the housing. Any suggestions on it,
I agree that the housing seemed torqued down to far. It was tight taking it off
Not sure what to do on the rebuilt. I need to decide to pull apart and clean it up, put together or built with lower compression for the procharger

You could mill that flat again or if you dont have a mill use sand paper on a flat surface like a surface plate of a piece of glass

It appears that the distributer was not adjusted properly and also put pressure on the oil pump. There are brass metal fragments in the oil pump rotor so... It looks like the engine is coming out. 4 years to get it together and 2 short drives LOL. (I will consider it as a total car mockup) I guess I will be building the procharger engine earlier than expected. Time to call Dwayne for some cylinder head work too.

I know this is small comfort, but it's better to find it now, rather than by driving over the crank.

The distributor shouldnot be able to push on the oil pump. thats what the dist shaft bushing is for.

I know it sounds too simple but I have had the screw that hold the relief spring in the pump back out.
That happend to me , relief plug unscrewed dropped oil pressure. Pulled the pan, bearings, couldn't find anything. Then the boy's on Moparts told me where to look. Simple fix, used some lock tight to make sure it didn't happen again.
it's ok to butt heads, just don't do it with a butthead

Thats what the builder said, but the prior owner used an MSD with an adjustable collar and it may not have been set right. Too deep
I doubt it... the dist shaft with a collar still would be pushing on the intermediate shaft and the bushing below it

Switched the timing cover and the guy had to make a new button.
He indicated that something may be wrong as he had to take a lot out to fit. This could be an issue
