Possible blown head gasket

[cdiesel]

Ok so the problem is puking coolant, but it never over heats ect never gets over 197 runs steady at 194. My truck has 4" turbo back exhaust, Mini Maxx, and S&B intake. I run it on the mild tuning and occasion wild. I'm going to try the degas cap, I also have an egr delete sitting here but have not put it on because the truck only has 53000 mi. Should I return it to stock and take to the dealership? I just find it hard to believe that it has blown HG's when it does not over heat.

Could be your degas cap, I have one sitting in my garage you can have if you wanna give me a couple dollars for mailing lol. When you drive your truck do you hear a high pitch whistling other than your turbo? It should sound like a tea kettle whistling. Look up powerstroke help they have a kit that will pressure test your coolant, if it is over 16 psi ( which is most likely is if your bottle cap is functioning properly) then you have blown HGs.

Go to autozone or O'Reilly and borrow a radiator pressure test kit. Make sure it had the adapters to test the thread on caps. Test your cap first. If it doesn't hold 16PSI, replace it. If it holds, test your cooling system. Put the tester on the degause bottle, set your e-brake, put it in drive and brake boost it a little bit. If you can see the pressure increase rather quickly you have a blown HG.

The only thing I have noticed is my EGT is getting high faster.

So I just went to the local parts store and bought a new degas cap then drove around and got on it a few times it did not puke coolant, maybe I got lucky I will find out tomorrow though.

Well I took my truck for a trip again this evening had it up to highway speeds took up some long steep hills flogged it a couple of times and it did not puke, crossing my fingers.
