Hi All,
I own a 1990 740 gl auto and it has about 185,000 mi on the clock. (one of)My new problem(s) is that the engine is leaking oil. Well, not just leaking but leaking pretty bad now, mostly under highway speeds. Oil has saturated all the way to the rear axle from driving. I have just gone through a quart in about 300 mi of mixed driving and the motor does not BURN oil. I noticed that oil has stained the valve cover around the oil fill cap and down to the bottom of the valve cover making a wide swarth. Not a lot there but it suggests to me that there is too much pressure for some reason. Is this cap supposed to have a small vent somewhere? I could not see one. I don't have an oil pressure guage and the idiot light has not come on as of yet.
I read on another post that these motors will leak around the distributor.Is that right? This one is in back of the rear of the valve cover and hard to view. It looks from the bottom of the car that the leak is coming from the rear of the motor somewhere. I am just hoping that it is not the rear main seal. I checked the flame trap and it is clean. The car runs ok but needs to be tuned again.
Any help or ideas that anyone can give will be greatly appreciated.
Thanks,
Don
