So mine is cracked down near the exhaust manifold connection. Coming clean, I broke it trying to remove the egr valve, thought it was loose but when I went to break it loose from the intake, "pink" was the sound it made. Getting to this thing looks like 6 different ways of painful. Not much room to manuever. Should I find a crow's foot or is there a better way. As with all exhaust components it's well rusted and I'm sure will make me worry about getting it off until the part shows up. I should have just put some electrical tape over the CEL. I was just going to clean the valve to make sure it wasn't the problem. The DPFE was replace about 8 months ago, if it proves to be the problem I'll be kickin' myself.
