Yes 45 lbs at idle from the main galley on the block. Nothing up top. With gauge removed from top sender, oil does come out the hole when cranking but not geyser like, more slow roll. Lifters are getting oil, but not much. Nothing coming out push tubes. I tried blowing 65 lbs of air backwards into the top sender port, just pushed oil out the lifters and squirters, can't really tell a major leak spot

And bring it went from perfect pressure to noth No on the gauge in a second or two, could mean blockage or major leak. I did replace all the driverside lifters. Going to do passenger side tonight.

Oip filters have a bypass to so if it gets clogged will send dirty oil to engine instead of no oil.....

Being that its good chance you may need remove engine and dissassemble amd rod out every oil galley to rid block of debris

Yea that ain't happening. It will go to scrap before I do that.

Oil filter was a stp one for two days, then it got a Napa gold.

Thursday I will start prepping for engine to come out. Going to pull pan and get a good look at the squirters. Then if I can't find anything I will pressurize the oil system and find the leak. I still don't think it's a blockage

I had it apart 4 weeks ago before I installed this engine. Resealed everything. Nothing was in the pan. We did swap oil coolers with a known good one, no change.

I know it’s not at all helpful but can I say it’s pretty neat to see it running with no intake or valley pan?
