Also, to answer a few questions, I still do not know what happened.

The car was running great and I noticed no issues before the big bang.

You'd think an ordeal like this might scare me away but the more I dig into this car the more I know it's the one for me. I hope to be back on the road soon.

Check your thrust bearing....very possible it wore down, and the gear came off the oil pump shaft, thus killing oil circulation....thus boom...

Something new I just found out about on my 78, research says...this is a very common failer that most aren't aware of....it would start with weak pressure...

This is pretty much my worst fear. My 220d is rough for now, but out of all my cars it's my absolute favorite and I drive it every day. Fortunately, my oil pressure gauge is consistently pegged and only drops on the hottest days or going to idle after interstate speeds--and even then never below 30psi. Hope you can find out what it was, source an engine, and get it back on the road ASAP!

The exhaust sound of your rental car?....... That's the Peugeot Sound! (A little Pacific Northwest humor there).

Jay, ' thrust bearing' ..... are you referring to the play for and aft on the crankshaft ?
That is seldom mentioned around here... but very important....I suspect few check and renew that even when they have the engine opened up enough to easily fix it...

Ever since hearing of this with that 300D, I have also become concerned about that oil pump bushing on my old 220D. The motor has run well for the 30k miles I have put on the vehicle, but the oil pressure has always been towards the low side (pegged when cold or over 2000rpm, but ~15psi at hot idle). While that's still plenty to lubricate the engine, I don't think the worn bearings in the bottom end would be able to afford any lack of lubrication from oil pump problems at this point.

Any thoughts on to how much that oil pump thrust bushing would cost at the dealer?

Maybe the rod just broke. It looks like it broke and the big end punched a couple holes before the engine stopped. There might be evidence of fatigue in the parts. Maybe a void in the forging.

United Flight 232 experienced a fatigue failure of the compressor rotor for the same reason.

I have never heard of a rod breaking from fatigue when the engine had good oil pressure.

The car had great oil pressure before it blew. That doesn't rule out an oil pump failure of course, but it wasn't showing any early signs of failure.

Also, and I'm a little embarrassed to admit this, the car started right up after the incident and I drove it onto a U-Haul trailer. Probably not the smartest way to do it, but it sure saved us some hassle.

The EPC shows two part numbers: 126 180 00 44 and 615 180 00 44. The first one says it's threaded M8 and the other is threaded M10. I guess there's no way to know without checking to see what's inside the engine. Plugging the numbers into Pelican's part search returns the genuine part at $171.25 for the M10 and $154 for the M8.

I don't really have a hankering to get into checking this, myself...unless someone else has done it before and can give advice

That's what scares me the most!
