Coolant coming out somewhere around the degas bottle, but it is not coming out of the cap. Popped the hood for inspection this afternoon(as I usually do), to make sure everything is intact with no leaks. Kiss of Death stared me in the face. As stated, it did not appear to be coming from the cap and preliminary review led me to believe it was coming out of one of the 1/2" dia. hoses that go to the top of the degas, so I cut off about a 1/2" from both and re-clamped. Took it for a hard run and came back and it was there again. The leak appears to be around the intake duct or above it as nothing below it shows any signs of leakage. Therefore it points to something associated with the degas. Maybe I have a split in the tank somewhere, but it only leaks when you dog it. When I released the cap, there is pressure on it, but not like I had when it had blown headgaskets. I would consider the pressure observed as being normal.

Nothing like sitting here pounding your head and trying to figure out what I may have bent, crushed, poked or otherwise pissed off to have this happen. Last night I finished the CCV mod. and I had to remove the Intake portion (which is nicely coated with coolant now), off to get at the CCV hoses and to re-route. Unfortunately, the leak has to be above the intake and it is spitting down on it. Which puts it back around the degas bottle/tank/reservoir.

Any ideas folks?

 

The bottle is probably cracked, they get brittle and I've heard of it on the 6.0's before.

 

Yep, not uncommon. I'd just put a new bottle/cap on there...

 

Thanks guys for the input. That's the logical approach. Man, the dude at the Parts dept. at the local Ford, I think he likes me. He sees me coming and starts grinin... Damm perve. I'll stop by NAPA and pickup some more 1/2" hose also and that should eliminate those 3 elements as being the cause.
Oh, I also noticed something else: Every time my dog goes outside with me, he goes directly to my truck and pees on the left front wheel! Is he making a statement?

 

I had a similar issue with my '07. There was white residue all over the overflow tank and she went through a full gallon of coolant in a little over a week. I was shittin' bullets thinkin' my EGR went out but suddenly it just stopped, no more pukin' coolant, no more residue. I'm not sure what happened but I'm glad it stopped.

 

Have you added coolant to it? You probably have blown headgaskets using that much coolant. Usually it stops when the coolant level gets really low. Do you still have heat in the truck? Is the fan kicking on a lot? Hows your coolant level?

 

You ever felt like a Dork? I do. The good news is, I found the leak. Even better news, it ain't coolant. After changing out Degas bottle, it still leaked. So, I performed a highly strategic maneuver. I wrapped a white towel around the degas bottle (with tie wraps) and executed radical throttle positioning to attain an egt of 1450 on the highway (oh still haven't found my speedometer as it buried somewhere along the way). Got back and towel had no red coolant marking and degas was clean like I had just purchased it (imagine that). Nevertheless, there was still spots all over the towel and intake duct. I rub my finger across the spots and made a startling discovery, it ain't coolant. It is OIL coming out my broken dipstick! Hell I didn't even know it was broken. I guess it pays to inspect a little closer instead of faulty conclusions on my part. "I'm a DORK".

 

It's all good, at least it's a simple fix. That's a good thing. The question is, how the heck did that break?

1450? I've seen the needle on my 1600 degre pyro buried more than a few times. It moves faster than my speedo does.

 

Yepper, already got a new one on and it has stopped leaking. I have run the s**t out this truck trying to diagnose this simple issue. I believe the engine is going to hold together quite nicely too. Only thing left to do is a tranny flush and new tires. Likely to go with the Pro Comp Extreme All Terrain.

 

They are an excellent tire. I know two of my buddies are currently running them. One on a 2002 Ford Ranger, and the other on an 06 Dodge 2500 ***-apart. Both are very satisfied with them and both have run other pro-comps before.
