Truck is at bruckners truck shop. Air compressor is being replaced by new one right now. I'm hoping that will solve my problem as you have suggested. But i'm not 100% sure that it will resolve the issue. My concern is that i believe the over pressurizing in the cooling system is what caused all these failures and that it will contine? As i replace a new item on the system it's just finding a weaker point of exit. Thus busting somthing else. something that i failed to mention is that i believe the root cause of this problem was that about a month ago i had my truck serviced and they over filled the motor with motor oil by at least a gallon or more. That busted the gasket on the oil filter housing and the gasket on rear valve cover. Fixed that and then the overpressurizing on the cooling system began. Do you think that overfilling caused all of these failures? Could that also cause the gasket on the air compressor to fail?
over filling the oil system, would not cause pressure in cooling system, yes it will cause leaks , in rear and other places
of oil system
I believe this is just a Fluke, , be a engine re builder 34+ years , I can say this with sound opinion
the 2 things that will cause this is Compressor head gasket 98%
the other thing is injector o-Rings
But I would start with Compressor, which you are about to do
