Transman, TJP- ironically I am Catholic. Father, about that exorcism Mass.. Cab- made some notes and will follow through with recommendations. Will post findings. Me too. On a serious note, I was not making fun of your predicament. It’s a phrase we use a lot around here That metallic noise, could be a lot of things. Might want to try the old metal rod held to your ear trick. Place it at different points around the engine and see where it is the strongest. Try rocking the crank back and forth when you hear it, see if it’s slop in the rotating assembly, etc. At this point with all the fuel you had in the oil, it’s probably a good idea to pull the pan. Check the rod bearings, look up at the bores. Checking the filter isn’t going to be conclusive, you could have wounded the bearings bad enough yet not put any metal in the filter.

The filter looks good The bypass valve doesn't: down: Take a good close look in the oil pump top in the bypass valve chamber and see if it is damaged or not, look for grooves or scratches matching the marks on the bypass vale or any tiny debris inside it or in the removable plug I'm sure the bypass valve stuck open causing the no or very low oil pressure I've had that happen more than once when a part failed like a valve spring breaking or another small piece got caught in between the valve and oil pump top chamber I cleaned and polish the valve and made sure it would slide in and out of the chamber dry and reused them after wards with no more problems in both stock pumps and a Mildon aluminum pump cover As far as checking the motor for rod bearing damage you can take all the spark plugs out and try rotating the motor both ways for several revolutions both ways and see if you can feel any differences when reversing directions or not if you can feel a difference take the motor apart. If you can't feel anything, put everything back together and prime it with the plugs out and spin it over on the starter watching the oil pressure before running it again

Once you clean the pump and internals check and see if the relief valve will fall out of its bore from It’s own weight.
If it does, as a trial you can assemble the pump and reinstall and see if you get pressures. I have seen much worse pump rotors and valve function just fine. I would check rotor face clearance while you have it apart - I think max is .004” across the top of the rotors to the body.
As for trying to determine the internal condition of the engine, especially the bearings you will be well served by just pulling the pan. The old saying - “motors run the fastest just before they blow up” could apply here.
You still have to find the source of that clicking. And if those are bubbles in the filter, it looks like you are sucking air. Not sure if s stuck relief valve would do that.

Im goona jump on the ejected lifter idea, just too much like an issue I chased when younger and got to the lockup stage after running as described and trying about 46 fixes with zero luck.
Good luck though!
