Hi all, I have a 2003 2.8 crd jeep cherokee. I have noticed that end of egr cooler (rim) is missing & there's no pipe so I have an open hole blowing exhaust gases up all over radiator fill bottle & surrounding area..I don't know if it became blocked & exploded off ?.. Can I just block the hole that should have a pipe on it below radiator fill bottle or will this cause problems ? Jeep drives around fine at moment but I'm breathing in exhaust gases which isn't great..any help greatly appreciated. Viking Bill.
