Ok i will pipe in. These are all just ideas and information. Did you remove the pressure relief at any time when working on the cover? Remove the oil pressure sensor and crank it over to see if you have flow. Yes your going to make a mess so be prepaured if you have flow. if there is flow you have a bleed upstream in the block somewhere. No oil pressure is a loss of prime (no flow) or loss of restriction (flow but no resistance). the oil flow is one thing, pump moving fluid. Oil pressure is secondary and pressure is created by tollerance of bearings and the restriction they create. imagine turning on a hose and water flowing, then putting your thumb on the end to create actual pressure. You can (and i have) stick the pickup in a bucket of oil and start the engine with the pan off. (be prepared for the biggest mess ever.) You can then see if there is a bleed but make sure you have flow first. Make sure you have the correct gasket for the timing cover, there are a few different ones. They seal great when done properly. Dont use a lot of silicone just a super lite smear to hold the gasket in place.
Pressure relief was not removed however the whole cover was put in an ultrasonic cleaner. After removal I physically pushed the relief back and forth and could feel it landing on the stop.
Oil pressure sensor removal, this is where I have my gauge hooked up. In the process of trying two different sensors there was no oil leaking out of the whole after a start up. I do have oil in the oil filter when I removed it and remember, the first start up right after the repair it primed perfectly and I had oil pressure. Drove it around, shut it off, started it back up with the light going out as it should, wayyyyyy batter than with the previous oil pump. It was the morning after I started it to confirm the repair and that's when the zero oil pressure started. The gasket I used for the timing cover was ERR7280. I also removed the oil pick up tube, ran that through the ultrasonic cleaner as well, I even sanded the flange to make sure it was flat, I also used a brand new gasket on that as well.
I bought a new used cover from Will just now. I'm going to tear mine back apart and start measuring tolerances and look for scoring that could be an issue with the pump priming. I also bought block off plugs to eliminate the oil cooler just while I sort everything out.
I really appreciate the input from everyone. This is probably one of the more tough diagnostics I've ever done because of the four sets of gaskets I've bought and the lengthy tear down process to just to try something different lol. I will have it fixed and I will post on here what the issue ended up being. I needed to take a step back and post on here. It's nice to have a place where like minded people can provide input. lol
