EGR valve= Dumbest thing on my 6.0

Well a few weeks ago running WOT with my SRL I noticed my truck would puke. Fast forward a week got a new degas cap. Still didnt help. Well since with the tunes my SRL shuts the EGR valve off I've ran it for a week just stock and today decided to take the valve out and see if it was damp in there. Holy cow! Why would anyone think that putting exhaust/ soot straight back into your intake would be a good idea? I understand the idea, and maybe on a gasser it may not be bad, but wow. Just looking at the bottom of my intake and scraping it with a screwdriver made my sick. As for my findings, I dont know what good can really look like in one of these things but, it wasnt damp, but there did seem to be moisture. I took out a chunk from the bottom of the intake and squeezed it and it just turned to sticky goo. Same for the soot on the valve itself. And being that I live in grand ol California, EGR delete is outta the question. As for my findings what do you all think could be going on? I dont get puking with the truck stock, just a tune and a new degas cap didnt help. Is there anything else I can check to see if its an egr cooler or head bolt problems. ( I wish it was head bots so my warranty could fix it, I have APR's waiting as for unfortunate day).

since it only pukes with the tune it only stands to reason that your headgaskets are leaking

That makes sense, thanks. Is there a good way to confirm it for sure without it being tuned?

Did you read my link? Testing is the only way to know for absolute sure.

Ya I did and I will try it out, but since he is a tech I was just wondering if there was something that me might say to do the directly test the headgaskets.

You could always do a sneaky egr delete, remove the actual intake side of the egr, bolt it back up and Weld up the egr cooler and run your tune so on an inspection it would pass the visual

Thats what I have right now, I did the same thing as Smokersteve and I left a 1/4in hole in it to keep just enough flow so it wouldnt throw a code (didnt help though). Next time I take it out Im just gonna plug it 100%. I wont do that though til I figure out what my issue is.

If you ever come across a quick and easy way to nail down which it is for sure - please post it up. Lots of folks would like to see that one! As of now, I know quite a few Techs and none will tell you that it can be done for certain without the vacuum / pressure testing. No doubt that some things will give you better indications of one vs the other, but still not 100%. Of course the conservative thing to do is to go after your headgaskets (and address both possibilities).
