Yes, the rockers are Jesels in the car.

They've been inspected, and all look perfect.

The pan had a few more roller pins in it. The pan is baffled with flaps, so there's many places for stuff to hide and stay clear of the pickup, until someone comes along and pours 10 quarts of oil really fast into the engine, and the "whoosh" of oil coming down from above washed some of those pieces that were happily living in the corner of the pan up and over one of the lips, and into the center "kill zone" pickup box area.

Upon startup, I suspect there was that tiny chunk that went instantly up into the pump and stopped it dead cold, before the engine even made a full revolution.

SO, of course I'd like to tear the motor down and do a full inspection/refurb/rebuild, but I also think that what damage that happened, whatever it might have been, is/was done. The engine still runs sweet, and no damage from the oil change was caused except to the oil pump (of which I have a new one).

I have 2 supermagnets that are going into the pan that should catch any more steel bits that may still fall from above.

My thinner screen I'm hoping will work to keep any more debris large enough to stop the pump from making it into the pump.

With these measures in play, I think I should be able to button the motor up and run it, and hopefully not have any more issues. No one can say for sure, but I'm doing something about each possibility.

My friend mentioned, that with the thin screen, to at least make sure to wait until the oil is hot to run the motor hard, as cold, thick oil won't flow through the screen the way hot, thin oil will.

Roger was running 20-50 oil in the motor. I planned to run the same, but I can also drop to 10-40 I think without any issue, and that would help with the screen-flow (possible) issue.
Oil pressures were high anyways, 80 at cold idle, 30-40 hot idle, 70-80 going down the road at 2000-2500rpm, so dropping a weight I don't think will hurt anything, and will definitely flow through the screen easier.

Bottom line is, I'd rather let the engine warm up for 15 minutes, than chance having another piece of crap stop the oil pump and go through this all over again.

Next year, I'll pull both the motor and box and go through both of them, new valve springs, valve job, hone, rering, new bearings (if necessary, or even just a full machine shop rebuild. Whatever it takes.

Right now, I have an engine that I can't afford to rebuild, and I think will continue to work fine with the mods I've made. Everything else checks out. Valvetrain is good. so I'm going to buton the motor up and put it to work, as Roger told me to do.

Again, this is NOT what I want to do, not what I was told it was, and not what I thought I was buying, but this is where I am now and this is what I'm going to do.
