Hi everyone we have a 2004 dodge 2500 Cummins with the 6-speed on our job site and today it started idling rough and it blew the valve cover gasket out at the very front of the engine my thoughts were perhaps one of the injectors came loose and sent pressure up to valve train which blew the gasket out it sounds like it missing when it's running just curious if anyone has had this happen or wants to take a guess at what went wrong it also leaked out 2 quarts of oil when this all happened the pickup is completely stock with a little over 100k on it
