There are a lot of factors that were messed with here. It could be anything from wrong bearings installed to worn cam bearings or even a cracked rocker shaft from not being installed or removed properly.

To my knowledge bearings are the same I did see those. As in oil pump I don't know if they even had it off just pickup tube. I'm starting to wonder if they should have put a new pump on it. This is weird but I did notice if you was pointing downhill the pressure might come up a couple psi at idle then back down. One other thing that was weird is a drove it 150 miles and when I parked it I checked the oil and it was just as clean as new and that has never happened. Maybe the new oil cooler helps that?
