Coach is currently at a CAT dealer. Engine diagnostic was run and it showed number six cylinder was not firing and there is a lot of crankcase blow-by. Tech said it was injector. Replaced same and still had the same problem. He did a pressure check on cylinder, that was Ok. He is now saying the engine needs to be pulled and head taken off for piston inspection.
1. Has anyone with a C13 had this same problem, and 2. Any suggestions on what might be going on.
thanks in advance - frustrated owner
