RMS Question
greetings all.
I have a 2001 RX300 AWD with only 125,000 Miles. I have had it since 2003. I take meticulous care of all my vehicles and most all maintenance on them.
Yesterday, after I left the house, my wife called me and stated there is a fist-sized oil puddle on the driveway. When I got home, I cleaned it. Then I ran another errand that took only 20 minutes of driving. This morning, the fist-sized oil spot was there again.
Climbing under the car, it is leaking in the typical location of a RMS leak. The aft bank of cylinders is for the most part dry. I cleaned up the oil on the bottom of the engine and removed the flywheel inspection plate. I then allowed it to run for 10 minutes or so. The oil was sweeping through again at the engine-to-transmission bolt on the aft side of the inspection area.
So, prior to ripping the entire engine/transmission out (or adding oil additive) my question is:
my wifes 2005 Odyssey just had the same leak last month and while researching the problem, I found the motor mounts to be shot. I replaced them and the oil leak stopped. Has anyone had the same success?
if just changing motor mounts, how would I tell if they are bad?
if adding oil additive, what is the success rate?
if dropping the entire motor/transmission, how big of a job is it?
I have done all of these before numerous times, but each vehicle is different.
thanks for any advice
Todd

I find it weird that I have never had a leak, and all of a sudden a fist-sized oil leak from the Rear Main Seal.
I am hoping that it is something else. I have already checked the PCV valve and it rattles and there is vacuum to it. But I ordered a new one anyways.
Is there any other ideas that you all might have that would cause such a large leak so quickly apart from a massive seal failure?
The engine mounts look good, and the PCV valve checks OK.

Have it checked by a competent mechanic. Not that you are not competent, but getting a second opinion [I think that is why you posted it here, but looking for a leak is best done in person]

I agree with you in theory. However,they are just going to say, “RMS is shot! $1200 please”
and since I do all my work by myself, I do not know any competent mechanics, which is hard to find in Orlando.

The thing to condor would be how much would you have to part with for the confirmation/diagnosis. Lexus would charge around $100. Other places would most likely do it for free.

This is true. If I can find a good mechanic to verify what is wrong, that is worth it.
I guess this is why I am posting here. To see if anyone else has had the same issue and found something else wrong that just makes it look like a RMS leak.
Anyone??
