Ok I had enough handtools in my truck to pull off the cold side inlet and everything is just caked in soot and what I imagine to be coolant? So if the EGR cooler fails it just leaks coolant right into the engine? Thats a pretty poor design, gotta hate all this emissons crap. All the hoses look good into and out of the EGR cooler, but there a little puddle in one of the ports from the EGR to the cold side, so it must be leaking in there, I cant beleive how caked up with sludge it is there, i've got some pics to post up later, but they aint pretty.
