'68 318 to carbed Magnum 5.2: Check my checklist

You actually have me confused on no oil to the drivers side.
Mags oil thru the push rods to the rockers.
The lifters have to be defective.
Spun cam bearing would loose oil pressure to the whole engine, and the passenger side would have no oil also.
Here is a pic of a new roller for a mag, I assume yours look like these?

The driver's side rocker arms and pushrods are getting zero oil - that's with both the lifters that were in there (which were oiling previously) and the new Sealed Power replacements.

Yes, they look just like those Oil through and oiling port to the top on the new ones. The old ones have oiling ports to the side (see last photo in my previous post above).
