Well, compression test says 150, 150, 0, 0.
I can hear the air rushing from 3 to 4 when testing 3, and 4 to 3 when testing 4.
Starting the teardown now. Waiting for the coolant to drain overnight, and will continue tomorrow after work.
Hope it's just the head gasket, but I'll find out more as things progress.

Thanks!
