I troubleshot this problem to the fuel filter. It may have started when someone did a replacement. I found that some brands of fuel filter used a wrong size grommet which leaks just enough to cause the problem.I have a 2007 Grand Cherokee Crd and over the past month I've been having an absolutely awful raw diesel smell coming into the cab and for I can't figure out where it's coming from. The engine is clean and there is no diesel or carbon residue/build up around the injectors or really anywhere on the engine.
I'm at a loss and am wondering if anyone on here knows of any good shops in the portland Oregon area I could take it to that will be able to find and fix the issue. Any help is very much appreciated! Thank you in advance.
