RE: Rebuild
Not good... Check the air compressor, I'm not sure how it is done on the 2350, in regards to the piping and the exhaust side removal, someone can chime in on that.

RE: Rebuild
Exhaust gases leaking into your cooling system.

RE: Rebuild
Do you mean the air compressor putting air into the cooling system?

RE: Rebuild
Yes, but more than likely it is a fretted liner, as you did the block test and it failed. The air compressor, if having issues will put air in, or pressurize your coolant system, which you are having issues with. Will there be exhaust gas in the compressor air? Doubtful, but something to rule out in regards to air pressure in the coolant system. I would at least check, and rule out more costs/expenses.

I have never trusted those liquid block leak test kits. They often give false positives... or don't detect anything at all.


- Only way to really tell if engine has liner or head gasket issues is to pull the oil pan off the engine and pressurize the coolant system over night to a full 20-psi and then the next day, turn engine by hand with a wrench while someone listens for gurgling form a cylinder and checking if there are droplets of coolant... or if there is any coolant pooled up anywhere on the bottom of engine somewhere.

RE: Rebuild
I may have false positive but i am not sure. The test stays blue in its bottle. I just did a control where i am in the cab(i washed out the tester and dryed it) the liquid is blue until i suck air trough it for a couple minutes then it turns green.

Is there a faster easier way that can be done at the truck stop or at the house? I do not have anything that i could keep 20 psi in the cooling system, or really any where i can drop that oil pan.

RE: Rebuild
The test liquid turned green within it's own bottle after being shaken
