Summary

THERE IS AN PLASTIC PLUG IN THE OIL SYSTEM THAT LEAKS OIL FROM THE ENGINE ON TO THE EXHAUST MANIFOLD. THIS WAS REPORTED BECAUSE OF INCREASED OIL CONSUMPTION, VAPOR IN THE ENGINE SPACE AND A SMELL OF BURNED OIL. THE PLASTIC PLUG IS KNOWN TO LEAK AND MERCEDES DOES NOTHING ABOUT THIS DURING WARRANTY AND INSTEAD WAITS UNTIL THE VEHICULAR IS OUT OF WARRANTY CAUSING AN INCREASED TIME FOR A FIRE POTENTIAL. THIS CAR IS DRIVEN ON CITY STREETS AND HIGHWAYS WITH THIS FIRE POTENTIAL.

Summary

I DID SOME RESEARCH ON MERCEDES 3.0L DIESEL MOTORS AND THERE SEEMS TO BE AN ISSUE WITH THE SEAL FAILING ABOUT 50,000 MILES CAUSING THE MOTOR TO LEAK OIL AND THE SEAL AS WELL AS THE OIL COOLER NEED TO BE REPLACED. IT IS SUCH A COMMON PROBLEM ON THE 3.0L DIESEL ENGINES THAT WHEN YOU CALL ANY REPAIR SHOP THE FIRST THING THEY ASK IS IF THE CAR IS A DIESEL. ALSO THE SEAL REPLACEMENT IS ALL OVER THE MERCEDES BLOGS SAYING THE SAME ISSUE ON THE 3.0L DIESELS. THOUGHT IT MIGHT BE SOMETHING TO LOOK INTO AS IT IS AN ENGINE SEAL PROBLEM AND IS OCCURRING CONSISTENTLY IN ALL THE 3.0L DIESELS IN THE S CLASS, E CLASS, ML CLASS, G CLASS. ALL MODELS THAT MERCEDES SOLD THE 3.0L ENGINE IN THE US.
