Bought my truck in December 2011 drive primarily on weekends, with occasional 4hr road trip to see family.This past weekend my truck gave code for oil cooler. Getting coolant flush done on Wednesday then going to replace oil cooler and do delete. In prep for work to be done, i popped hood today to start marking wiring and noticed coolant looked low. Pulled egr valve, and horror struck me. It looked slightly damp in intake. Can't figure how to put pics in post but have a couple of egr valve. The top o ring looked damp, but not the bottom one. The valve was covered in soot, but still moved freely. I tried to smell down in intake, and it did smell like coolant. Is this a for sure blown hg? What the hell do i do now? Truck is all stock with edge evo running +40hp. Don't tow, don't hot rod, truck has 116k miles on it. Don't know the previous owners story.

 

Coolant low/damp egr valve area is sure sign of a blown egr cooler. It needs to be deleted or fixed asap or it will likely lead to blown HG's if not already blown. If it hasnt been puking(not always a sign). Need to check coolant system pressure to be sure about your headgaskets

 

Coolant in intake is blown egr cooler, coolant puking out of degas bottle is blown head gaskets, oil in coolant is blown oil cooler. if the egr cooler is blown it is because the oil cooler is clogged and didn't allow enough coolant to get to the egr cooler and it steamed up rupturing the egr cooler. coolant flows through the oil cooler first then it goes right to the egr cooler, that is why they are always related.

 

Hey, thanks guys. Im going to keep my fingers crossed, and do the work as planned.
