from what i understand, and please correct me if i am wrong.
Speaking from an IMS standpoint. The bering is supposed to be sealed, it is bathed in oil. If oil is getting past the bering and dripping out of the RMS, then it is safe to assume the bering is not sealing.
The plastic seal allows oil to enter, and may not flow around the bering freely and the bering fills full of old oil.
then the old oil breaks down and the bering wears and the IMS fails.
So thinking of that alone, it is better to have as much fresh oil in the motor so that a little fresh oil makes it into the bering and lubricates the bering.
Also from that stand point, driving it hard may push oil into the non sealed bering and replenishing the IMS with newer oil. Hence the superstition that driving the car hard is better than babying it from a IMS standpoint.
does this sound resonable or am i totally of base?
I will say this... I have had three RMS seal repairs. I change my oil every 5 K miles, and my IMS was going out at 65K. I am courious if it should not be closer to 3000-4000 miles for an oil change.
