    run or not is up to you, a quick main/rod bearing inspection wouldn't hurt.

    But I agree, it's probably not hurt.. because it had some oil pressure for most of the run.

    Filter seal should be no issue at that psi.. was it simply not tight?

    Never a bad idea to go to a different style filter, I like the Oberg stuff myself.

    I used to see this when I changed the oil on plow trucks for a property management company. Doubled up seals, leaking like a sieve. Jim

Wasn't much in there. maybe a qt. probably less. Cleaned the system one and installed it. added 6 qts of fresh oil, pulled the belt and spun up the pump with a drill. Started the engine and ran about 10 mins. fully warmed up. Shut it off. let her cool and then opened up the system 1. Element was clean. Sparkley stuff in the pan ,There always is but its non magnetic and so fine I cant feel it between my fingers. Nothing on the magnet.

    This is a vid of the car running. I cannot for the life of me figure out how to find it on my phone and upload it to the computer.

    Thanks for the heads up Jim. Took care of that

    Oil pressure is look'n good in the video Steve! That is as long as those were the same pressure levels at the same rpm and temperature as before the incident.
    As far as the photo of the oil, ... some of the "sparkley stuff" looks fairly large to me. Also I'm not sure what bearing you are using but the top layer of bearing material is not magnetic (I just scraped a used bearing from the rotating assembly I sold you, and tested with a magnet to be sure). You would have to have some mighty sensitive fingers to feel it, I couldn't.
    Copper and lead alloys are common in tri- layer bearings. They give you the embeddability to help absorb small particles.
    Are you using a bronze distributor gear? I know there wouldn't be too much of a load on it because you are using an external oil pump.

    Glad you saved it. Probably just some lead/tin plating from the bearings flashed off, should be plenty left on the mating surfaces for the rod/crank journals.

    If it happens again, though, I'd change all the bearings & plastigage the clearances...make sure you didn't lose any iron on those mission-critical parts.

    For uploading the video from the candy bar phone, the file is stored in the DCIM folder as an mp4. The phone needs to be connected via USB to the computer, and then a pop-up window on the phone should ask to allow the file transfer, or trust the computer.

    The oil pressure is exactly the same as before the incident. YA know. I never thought about the bronze gear but I do have one in there. The first go around with this engine I was using the HV pump. When the adjuster unscrewed and caused the melt down I did away with it in favor of the R1 but left the gear on the dist.

    Is this a wet sump belt driven pump?

    Its a wet sump. Pulls directly from a baffled sump in the pan . goes from the pump to a remote filter and into the block through an enlarged hole with #10 AN line in the factory sending unit location and another #6 into the back of the block in the right lifter galley. NCM_0576.JPG NCM_0618.JPG

    Steve, you just described a "Wet Sump" system with an external pump/pick-up.
    Dry sump system will require a special oil pan and have a separate oil tank with a multi-stage pump. One or two stages suck the oil out of the sump (hence-Dry Sump) and sends it to a holding tank where another stage draws it from the bottom of the tank and then pumps it back into the engine (through a filter). That's a crude explanation, but you get the idea.

    Agreed that’s the same as my wet sump

    OK briz I have to ask, I see and auto shifter in the regal, but looks like some kind of adapter for a clutch bolted to a jw flex plate???? I know it's not thread related but my mind is wondering

    The reason I asked if the 0il pressure is at the same temperature as before the incident is because in the video the water temperature is pinned on the low peg of 140* and just starts to move at the end of the video. What is the oil pressure at when the engine reaches its full normal operating temperature?

    You are, as usual correct Larry. I was having a senior moment. Its happening a lot lately!

    I had to go back and look for what you were referring to. That is what they bolted to the flex plate to attach it to the engine dyno.

    Once at the track I'll warm up the car to full temp. around 180. In between rounds the electric fan and water pump will cool the heads and intake pretty quick. Block is hard filled. Once they start rolling up in the lanes I'll try to get the engine back up to 160 before my turn to stage. By the time Im back in the pits its never more than 180/190. Theres other vids I shot with a go pro inside the car during a run that show the op maxing out around 80 at the shift point. I shot that vid just a few mins after I started it up that morning and did let it run with the water pump and fans turning for 10 - 15 mins.

    In this one it looks to be 90 PSI @ 6200 rpm. was late on the shift.
