Today I could smell diesel looked under hood on passenger side oil was all over air cleaner hood couldn,t see where oil is coming from rev truck up still nothing. anyone no what's going on.
Watch your oil levels. If they go up, you have a fuel leak in the engine. Usually one of the jumper lines from the common rail to an injector. That won't spray oil outside though.
Maybe the vent tube cracked? Runs from the front of the oil fill housing down the right head and block
