sorry for the semi-hijack of your thread 2000LaDe. i only wanted to bring your attention to a potential problem. your build is intriguing. the enclosure looks like Fort Knox. i have an 05 and have been looking for ideas for the door panels. i've also ordered some material to gain some experience with fiberglass.
If he were really puking in the sense you're talking about there'd be a lot more and in little tiny dots all over everything.
Thats about normal for most degas bottles, hell the degas on my tacoma has some on the outside, but by nature that is what the bottle does. So thats perfectly normal for that psd
i never indicated there was a large amount of coolant. it could just be someone filled the bottle and spilled some coolant.
no it is not normal to lose coolant through the cap of the degas bottle on a psd nor any other vehicle with a sealed coolant system.
with the 6.0 puking or coolant coming out of the degas bottle is an indication of a couple situations.
-ford had a recall #05B32 or TSB 06-3-8 to relocate the fill level on the bottles. in a towing situation or extreme duty, the system is working harder hence more pressure and was pushing coolant out the cap. by changing the level to less, ford was hoping this would solve the problem and it did for some. what's funny google degas bottle and see what it brings up....better yet google degas bottle puking.
-bad cap
-i believe i've heard that flash boiling the coolant in the EGR cooler will also push coolant out of the cap. high EGTs
-extreme cylinder pressure (lots of boost and fuel) will cause the truck to puke. i've seen guys running tuners with big tires lugging the motor creating high cylinder pressure and heat. even towing heavy can do this stock. pressure is escaping through the head gasket and being introduced into the coolant system. the 6.0 has TTY head bolts and they literally will stretch letting the head lift.
-head gaskets letting loss. on a 6.0 when a head gasket is weak or is on the verge of going south you get the same scenario as i explained above under normal driving conditions.
