I even took the leak tester off and chucked it directly to my air compressor that had 100PSI of air and sure enough, no increase in hissing. I'm not convinced it's the head gasket... Something should have shown up!

I would also like to add I did them twice. I started with #1 and worked to #3 then did #1 again and repeated. Same results both times.
That's great news. Maybe the head gasket is okay.

Have you tried taking the thermostat out?

I don't recall if you've done a flush with a hose.

Maybe there is a buildup / blockage somewhere that can be flushed out with a hose.



Wish I could post that link without it opening up.
