I decided to do the job myself.
It definitely wasn't worth 3k.
Dropped the pan, easy except I broke it trying to get it loose. Got another on ebay for a reasonable price.
The screen was of course not plugged.
There was what seemed to me to be a lot of superfine metallic particles in the bottom of the pan. Enough to run your finger through and feel some depth. Maybe a 1/32 of an inch?
Pulled the pump. Took it apart. It seemed fine to me but I replaced it anyway.
Everything back together, new oil (mobil1 0w-40), new filter (mann) it's pretty much the same. Maybe a little quieter when it warms up but still:
quiet as can be when cold
lots and lots of top end noise when warm.
Thinking about it more, I'm wondering if perhaps lines to the oil cooler (this car has one, right?) might have gotten damaged, (perhaps crimped?) when the rear drive shaft broke and whacked things underneath and the shop that fixed it didn't notice that?
Can anyone clue me in on where the oil cooler is located and if there are external oil lines running to it?
