83 240D, why is my engine losing oil & how do I stop it?
Aside from the obvious reasons, such as it going past the rings, why is my engine using oil? I think most of it is going out the Rear Seal.
I was thinking of running a vacuum line to my crankcase. This engine ran beuatifully until last year and has been maintained well and doesnthave that many miles on it. Any solutions and ideas? The only thing unordinary is I cracked the aluminum line on the exhaust manifold running to the Intake EGR preheat and I plugged the hole on the Exhaust manifold instaed of rplacing the aluminum line. I would hate to give up on this car....... 83 240D, why is my engine losing oil? |

Two most likely culprits at this age are the front crank seal and the valve cover gasket. The valve cover gasket in particular will allow oil to run down the engine and off the back.
On the 616, a leaking oil filter housing will also look like a rear main leak. A leaking o-ring on the separator return line from the air filter housing, or a leaking separator will dump lots of oil, too. A clogged return line will dump it down the intake. Any of these can dump a couple quarts to a tank of fuel on the ground -- if you are getting oil drops under the car, you need to find and repair the leak. Bad valve guides or guide seals will cause serious oil consumption too. Blue smoke on startup or on decelerations is a clue here. Oil consumption doesn't suddenly skyrocket unless you seriously overheat the engine. Peter

Just looking at your car description- 1983 240d rebuilt engine.
Whom rebuilt the engine? It's very strange to have a seal failure in a low mileage. Michael
