Recently my vacuum modulator on my 420sel has allowed my transmision fluid to be burned in the engine, and I haven't had a chance to find a banjo bolt to read the pressure on the transmission so I can install the new modulator. I have just been topping off the tranny every other day or so. Today while playing with the car, I noticed my crankcase was overfilled with oil, and I have not done an oil change since last month and I know I didnt overfill it. In fact the car actually leaks a small amount. I smelled the oil and it does not smell like gas or transmission fluid, just oil. Is there any way the vaccum modulator leaking and my crankcase overfilled are related? Any help is appreciated.
