Head gasket question

[ktm300hater]

Is it possible to be pressuring up the radiator but still have 150 psi compression on all 8 cylinders

[Mach1]

yes, that pressure is much higher with a running engine.

If you suspect head gasket issue you can get this to help diagnose.

Autozone rents the kit, you just have to buy the fluid.

Can you smell gasoline in your coolant or see any floating oil?

No. It just blows it out the cap. I figured it was a blown gasket. Just wierd that it still shows good comp numbers. I'm ordering a set of cosmetics. I figured at 5 psi the 9333's would have held up.

I wasn't even beating on it just driving down the road.

They'll do fine at 5psi. Could be a bit of warp on the head or deck surface allowing combustion to push into the coolant passages but not between cylinders, hence the good compression numbers on static comp test. I'd bet a wet leak down would tell you more.
