All good advice. Actually got bold with the starter and did 3 different turns of10-15 seconds each. Spaced over an hour or so. Got the needle to fluctuate a bit on one of the turns. Not looking forward to unburying the sender but thats next on the list.
Frustrated update. Removed sender and hooked up mechanical pressure gauge I had from a turbo car issue many years ago. 3 cranking sessions of 20 seconds never produced more than a flicker of the needle and more interesting that no oil was in the gauge hose (although some sort of suction might have emptied the hose before I checked. There was an oil level almost up to the top of the sender port when I removed it to remove the sender. And from my previous posts there is oil in the filter so oil is moving on both sides of the engine. Thoughts?
Hard to say but since you had pressure prior to swapping the lines, I would retrace my steps and look over everything I did. Sometimes there is something that might have been overlooked. Any chance you removed the overpressure spring next to the oil return line and repalced the piston incorrectly?
This is a nerve-wracking thread. Sorry for your troubles. I’m also wondering if it’s a plugged or linked line. Any chance you have a Rothsport check valve? They’ve been known to fail on occasion.
Seems like oil had to flow for the filter to have filled up. I'm aware of the one lines propensity to kink and it isn't kinked. No Rothsport valve. I made sure to double check all lines and inlets as I re-installed but that might be the next step. I had a seasoned Porsche shop owner tell me today that I should crank the starter continuously for up to two minutes for a complete oil dump. Did so without results
Cranking continuously for two minutes sounds like a good way to burn out a starter motor.
Have you tried cranking for a few seconds with the oil sender unit removed? If you don't get a gush of oil then you know you have a blockage or the pump has somehow failed.
It doesn't take 2 minutes to build pressure from zero.
It does typically take more than 10 seconds. But just not sure I'd be suggesting to crank the engine for two minutes. That's kinda nuts. It should start to read - somewhere in the environs of 20-30 and if it doesn't, there must be an issue somewhere as you have seen.
Looking forward to hearing what it is in the end. I'm curious
Finally bit the bullet and started to drain oil. Crankcase first. Started to check for blockages and started with the oil inlet from the tank to the engine. I was 99.5% sure all towel plugs I used while cleaning and changing hoses were removed,,,, It's always that .5% that gets you. Found this Brad Penn soaked plug (looks like a goose turd) at the engine inlet. Removed it and filled everything up and finally good oil pressure! The saga ends.
This is terrifying, and is why I have switched from towels to using large silicone plugs to block lines when they're disconnected. You're not forgetting one of those!

Exactly. This is one reason I designed a set of plugs anyone can download and print for free. If link below does not work you can search for me (KLR-Tom) on printables.com.
