Puking Question 2

Took my truck in sig to dealer today because of puking. Interestingly it did not do it today and we are about 20 degrees cooler today than when it was doing it; about 78 degrees today. Could it possibly just be the degass bottle cap that needs replacing? Dealer is going to pressure test the cooling system, but was trying to stay one step ahead of them.

Mine would puke one day and not the next. The dealer had a hard time proving that the gaskets were in fact blown. The cylinder pressures were to spec. It finally puked when they gave a trailer a good pull up a grade. On dissasembly the gaskets were fine, the heads were warped.
