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.

Blockchek takes the guesswork out of it. For $40 it should be in every mechanics toolbox.

Well, I received new alternator today from DC Power Engineering. Once it was installed I was able to start my truck and get it up to temperature for testing any combustion gasses in the degas bottle. Using the Block Chek kit Dr. PGreenSVT recommended I am happy to report that my test was negative for exhaust gases. Interestingly I did not see the bubbling in the degas bottle that started my original concern. But now I know for sure my heads are in good shape for now:woot

Now you can quit worrying about that. Glad you came out clean.
