Sounds like you got some e-core versions!
I never thought at the time to check. Here is the short version...Towing RV in a trip, 1500 miles on oil change. Pull off the highway for gas. Start up the truck and ZERO oil pressure. I shut off the truck right away. Start it again..ZERO oil pressure. I rev the engine and bam - oil pressure. This than happens at every stop where reving the engine gets pressure up. Almost like a bad relief valve or something. I get to the campground, unhitch and drive to an auto parts shop. Grab a random Bosch filter and instantly - NO more issues the entire trip and oil change interval. Next oil change I use another bosch and no issues. Following oil change, another AC Delco and within 2000 miles...SAME ISSUE!!! I immediately replace the filter with an STP and issue gone. Now, a few years later and never using an AC filter again, I've never had the issue again.
