I have what I believe is the original 1975 timing cover and oil pump on my 304, 1975 CJ5.
Is it feasible to have Bulltear re-machine the oil pump cavity?

Engine was completely rebuilt about 5000 miles ago (15 years ago) by local machine shop with Edelbrock performer cam and timing chain set. Bulltear midplate, Sealed power oil pump kit.
I did all the assembly of timing chain, oil pump, cover..... as a rookie.
I reused that original timing cover back then because there was talk about the poor quality of aftermarket covers even back then.
Oil pressure has never been great, but ok. (I don't remember exact numbers as the jeep has been sitting for a couple years now because distributor drive gear failed.
Of course now the oil pump walls are scored because of that gear failure.

Regarding the distributor drive gear failure:
I think I must have reused the original distributor drive gear on the cam back then.
I have detailed receipts and I cannot see where I purchased a new gear.
It looks like one of my mistakes back then was installing a new MSD distributor with the steel gear with the original drive gear on the cam.

I have been doing a lot of reading on this site and others, so I see the many other things I need to look for.
I likely did not check the oil path from the cam bearing out thru the timing set back then either.

thanks for any help!
