I'd bet you had to much in it. If it's less than 2" from the top, it WILL puke.

 

I picked up a new cap today. I have not put it on as it was hot. The truck reached operating temp and there was no new fluid spitting out. One think I thought of, when the truck is warmed up, sometimes I hear a whistle just on deceleration. If I just blip the pedal, it stops. Again it only whistles when slowing and my foot is completely off the accelerator. Does that make a difference?

 

Just an update, first off, I figured out I DO NOT have an EGR cooler. I have a sinister delete kit with the EGR valve still plugged in. Anyhow I sucked out the extra fluid until it was about 3" from the top of the bottle and also installed the new cap. I made the trip again and absolutely dry as a bone. It was either the cap, or the level or both. I will keep an eye on it but the whistling is gone also. Thanks ALL.

 

So, did the puking start after a top off of the coolant?


The updated degas tanks have this new sticker on the side indicating the corrected fluid level.

 

Great news.

Your's looks a little full

 

Not my pic...just a quick google search, he's also a quart low on brake fluid.


I'm still running Gold and my level is close to the top, just not that close.

 

I actually just purchased the truck and I am sure the Dealer topped off all of the Fluids. Mine looks EXACTLY like that one, sticker and all. Mine stopped puking now that the cold level is about 1/4 below the low level on the sticker.

 

hahaha--he sure is lol

 

They did the same thing with mine when I bought it--they topped it off.
I got a bit of puke and drained a bit and changed the cap--no issues sense.

 

Well, I thought I was done with this issue BUT today I drove in my normal 135 mile Monday Drive. TODAY the white spots are on the bottle. It doesn't look like much but definitely let out coolant. It was a little warmer today (about 80 degrees).


It had been bone dry since I changed the cap until today. Should I start to worry?

 

You may have to bring the level down just a bit again--just depends on how much is actually in the degas.
Probably time to do a pressure test. There are a few posts on the exacts and what the pressure needs to be and probable cause based on what the pressure does.

Personally, I think it's your heads. This is, after all, the hallmark repair of the 6.0 liter PSD.

Since you said the EGR cooler has been deleted, if it were me I would go to NAPA and purchase a combustion leak test kit. If this test proves negative for combustion gases, it will have cost less in time and dollars than rigging up a way to test the pressure at the degas cap. If you test the pressure first, and that comes back high (20 psi or whatever) you're probably gonna end up testing for combustion gases anyway.

I would say most of the folks at this site have been down this road, and on the front end of the repair it may seem daunting; once the repair is in the rearview mirror so to speak, it's complete relief. At least it was for me.

Good luck.

 

Would a head gasket be intermittent? I have put on almost 2000 miles without issue...... Same drive back and fourth?

 

It can be intermittent; for some, it only manifests itself while towing. Mine started off intermittent- a drive down the interstate unloaded and when i got home i'd see a ring of coolant under the cap on the outside of the degas bottle. In the beginning this was intermittent, especially since i changed the cap a few times. Eventually it just became every trip on the interstate. Tested for combustion gases and came back positive.
Studded it; end of story.

 

I don't trust those exhaust gas kits. What if the show a positive and it is only residual from a blown egr cooler? I don't know if that's possible, but I wouldn't trust it for a $3500 gamble.

If the egr is deleted, the pressure won't build past 16 inked the HGs are toast.
