TINY BUBBLES....TINY BUBBLES...??

No not the song.....

I was checking my engine yesterday...just listening and looking things over. I noticed small bubbles going into the degas bottle. Nothing major but they were constant. I have researched PS.org and noticed this could be the symptom for a bad head gasket or oil cooler. My question: Is a small amount of bubbling normal or should there be absolutely no bubbles feeding back to the degas bottle?? Many Thanks.

Since you have an egr delete there is a good chance it is your head gaskets. Get some of this Block Chek - Store and check for exhaust gasses in the degass bottle. It'll let you know for sure.

Ordered. Many thanks Doctor Green. ;)
My pleasure. :thumb:
If it's bubbling air is being introduced somewhere.... The most probable cause on the 6.0 are head gaskets or egr cooler but seeing as you deleted yours .....
I thought i read somewhere that if you are using a ELC coolant testing for gases in the coolant dont give correct readings... Is there any truth to this?
Not sure. I would not think an ELC would have any impact on the results. The test is to test for exhaust gases as a result of combustion.
So is it possible to have a blown head gasket and not lose coolant ?

Yes, or the amount of lost coolant could be so small, you wouldn't notice it.
Where is it bubbling at? Which hose are the bubbles coming from?

Mine doesn't bubble, but can see fluid flowing that can at times look like bubbles flowing from the return line from coolant filter.

Humm.I. seemed to remember tiny bubbles coming from mine as well.good thing I am getting ready to do studs,but I wil checkk again this evening.
Blockchek takes the guesswork out of it. For $40 it should be in every mechanics toolbox.
Good call on the block check...Think I'll pick one up just to have.

To the OP...where and when exactly did you see the bubbles? Now I'm interested to see if mine does it.
Coolant comes out of the top hose and drips into the standing coolant. This causes some tiny bubbles. Check to see if that is what you are seeing.

I believe it is the line from the EGR Cooler?:dunno:
Ok here is what I found,at idle if I take the cap off the degas bottle I can see tiny bubbles constantly.When ,I turn on the high idle mod they go away,however from the outside I could not see the bubbles.I am going to get the test kit anyway. I dont have an egr cooler.

Could you see the bubbles only from the outside of the degas bottle ?

Yes, that is how I first noticed them. I was standing at the front of the truck while it was running and at temperature. The motion in the degas bottle is what caught my eye. I am down right now waiting on a new alternator which should be here Wed. Once I get it installed, I will check it out further.
