Doing some research. When you did the DOD delete, did you block off the towers in the lifter galley?

The towers were tapped and plugs were installed. The new valley cover has o rings that sealed them as well. I also plugged the extra bypass on the oil filter housing that bled off the extra pressure when the lifters were not in use.
Called the shop that did the work and he said it sounds like one of the cam bearings walked. That leaves the oil galley wide open and reduces pressure at the top of the block.
Looks like the engine is coming back out.
