I have 1994 Bobcat 853 with Isuzu 4BJ1 PK-3 diesel with oil coming from dip stick tube. I put balloon on breather hose coming off valve cover (next to PVC) to test PVC and balloon did inflate, telling me PVC is okay. Is there a second crankcase ventilation that could be plugged? Also there's black soot buildup in engine bay. After power washing and running machine for 2 hours, soot buildup was back. Engine does not visibly smoke. I'm guessing engine needs overhaul but first checking other things.
