Blown Head Gasket — Bubbling.

[Trudant]

Compression test:
- US Passenger side (4,5,6) all show 180 psi.
- US Driver Side (1,2,3) show 60 psi, 60 psi, 100 psi.

The coolant is under pressure because of the air forced into the coolant lines During the test.

So I peeked inside with a borescope. I can see fluid in the cylinders and bubbling at the head gasket inside cylinders 1,2,3.

Should I just go all in on a head gasket replacement or should I be looking for a crack somewhere?

No white or smokey exhaust. Just light coolant smell.

Thanks!
