Liner Height

Still getting air into the coolant system, not exhaust gas, just hoping it is remnants of my old Trip-Pak and the fresh install or the compressor. I'm stubborn enough to fix it, everyone tells me to sell the truck, but rates are up and freight is flying. The truck is still free and clear and actually running very good for a change. I just blew that. ;-)

If you're getting air and not combustion gases, I'd bet of the compressor.
Here's the test for that, and you'll like this one...
Disconnect your discharge hose, I do mine at the air dryer inlet. I do mine at the air dryer because you need to install a fitting to adapt from the discharge hose (JIC) to your shop air compressor hose (NPT). So it will be a male JIC to female NPT fitting, this is an easier fitting to find than the direct off the compressor head one.
Now comes the part you'll like...
It needs to be a nice quiet afternoon. You'll need a lawnchair, a box of beer on ice, and a Montecristo Toro sized cigar!
Connect your shop air to the discharge hose and open the ball valve pressurizing the compressor. Have a seat in the lawnchair, fire up the stogie, crack a beer, and relax. Your listening for gurgling in the cooling system. Sometimes it doesn't come right away, hence the cigar and the box of beer. I literally gave up thinking my compressor was fine, I grabbed the wrenches to undo my test fitting and reconnect the discharge to dryer line, and decided to go to the washroom first...it was when I was walking past the truck, after goin to the can, to the other side to undo the test fitting when I heard it! I wasn't 100% sure I wasn't hearing things trying to force find my problem, and I had to wait another 10 minutes to hear it again! Hence the stogie, you wait to undo the test until after the fine smoke to rule it out.
