Well I think it's time for head gaskets.. You guys think?

Last Friday, same day my egr delete parts came in, my truck (mods in sig) it puked for its first time. So I I did egr delete and oil cooler over the weekend, the egr cooler wasn't bad. Long story short truck pukes any time I run it hard.

Today I got the truck up to temp then released degas bottle pressure and teed in a pressure gauge, took it for a drive and if I put a good load on it climbs to 15 psi pretty quick then gauge flutters as it vents.

Did I do this test right? I think there toast

Leaking head gaskets sound pretty likely.

With coolant temps at 195*F (100*F ambient), I get 9 psig typically. After venting mine and running it hard for 100 miles the most I see is 2 psig (normally 1 psig) and that is with the coolant at 205 degrees (coolant pressure will go up about 1 psi for every 8-10 degrees on a system w/ proper coolant level).

Come on! Your supposed to tell me I did the test wrong and there good!! Lol.

Thanks for the reply. Is that about the best way to know for sure or is there a better test. I did a search and that's where I got the pressure test from

You can also do a test for combustion gasses. Link is below.

Also, I can send you Ford's TSB on it of you wish. Just PM me an email address.

My coolant level was about 1/4 to 1/2 inch under min line. Started my drive at 192* and 0 psi. After a mile or so I got it to 200* and venting at 15 psi. Not lookin good!

Yeah sorry to say bud your head gaskets are toast.
