I don't think the compression test results make sense. I don't think you're getting the gauge to seal on those two. And when you put oil down in there there was some oil sitting on the metal ledge that helped the gauge seal. I would maybe try another gauge. Unplug the injectors and make sure you're holding the throttle down.

Dry v.s. wet the oil should help a few PSI if you have piston ring issues. Which you probably would have known if you had and you wouldn't have gotten from losing coolant.

If it's running okay and isn't smoking, it can't possibly have 30 PSI on two cylinders.

I've blown coolant on my b58 and m52 and both were fine after hitting the red. Maybe I'm just lucky but I think it's overstated. And I think people also overstate the head gasket job and many end up junked over a medium amount of work.

I saw that one on Craigslist too and really wanted to go get it. Mine doesn't have a roof and a tow hitch yet but if it did .. that was a good buy.
