Ok guys, i'll keep this short. I've been having a problem for a while with coolant puking from the degas cap. So I finally rigged me up a little "tester" (30psi pressure in-cab gauge hooked up to the degas bottle). I did a few WOT from a stop and a few overdrive high boost runs and i never got over about 10-11psi on the gauge!
So, i'm not really sure why i'm puking coolant. I've bought about 3 new degas caps and the rim of the bottle looks perfectly flat. I was initially assuming headgaskets were gone again, but I would think that would cause ALOT of pressure in the coolant system.
Here's a little loop too.....I have a slight amount of oil in the degas bottle! BUT I don't know if it is recent or from when the last owner had the the oil cooler fail. (During that failure he replaced it, added ARP's, Black Onyx gaskets, decked the heads, deleted the EGR and added the coolant filter).
What the heck do I need to be looking at here?!?! I have a few videos of the "tester" that i'm going to try to load but i'm still learning my Mac.
