Head looked good, only one valve visibly bent. New lifters and valves and that head would be a runner.
Bottom end on the other hand, I might not be so lucky. No valve damage to the pistons, but the hole that seller said was showing no compression has erosion around the top of the piston.
It might be fine, or it might be a waste of time, a head gasket, and a bunch of single use bolts if that hole still leaks down or it blows apart in less than another 100k... I'll solicit some internet opinions on the facespace and see what the world thinks.
I might dig my other TDI out from under the workbench tomorrow and give it a close look (came from Brett's friend's car that Spencer and I parted several years ago, totally unknown history). It's definitely new enough that it uses the same pistons as this engine. Be easy enough to pull the pan and go in from the bottom as long as the bore stands up to very close inspection. New piston with rings lists at $125.
I know this car had the turbo swapped on it, and I actually found a piece of the cold side turbine on top of the steering rack. Wouldn't surprise me if that's what the piston damage was from and it's been driven like that for ~30k and was "fine"
