Had my 06 C2S 6sp in the shop yesterday at Porsche dealer in Calgary. Was told after my LOF that my RMS was dripping...and a $2000 estimate...When I got home I checked the garage floor and there was no oil on the floor. Had the car for 5 years and knew when I bought it that there were some rare instances with the car at new where Porsche warranteed the replacement of the RMS. Haven't had any leaks whatsoever on the floor. Perhaps it is seepage? Some say its an issue that can come up with a non-daily driver, but even then it is like 5% of the cars. Am I one of the lucky ones? Anybody here with a 997 have a similar experience with the RMS/service shop? Kind of up in the air on getting it done or not, that $2000 I feel can turn into $7K pretty quick once they get it apart. But I don't want to have big clutch problems either. If I am not seeing any leakage is this really an issue?

Thanks

 

I would tend to leave it alone, if no oil on floor, no drop of oil level, I would suspect dealership of being a Stealership. That happened to me
with a Honda dealer, I took the Accord in for an oil change and was told of numerous "problems". I have a very trusted independent Honda specialist,
when I told him what the delaer told me, he looked at my car and told me the dealership was telling me a total lie. None of the problems were problems at all,
borders on criminal behavior.

 

My M96 engine seeped from everywhere. I did have spots but only with 0 weight oil. I put heavier stuff and no spotting at all. My indy said leave em alone as the seepage was not hurting anything.

I would not jump to accusing a dealership of fraud, but they are in the business of fixing things and Porsche owners can be pretty demanding wanting everything perfect.

If you are worried, get a second opinion at another dealership if possible. For my old Boxster, I had a permanent flattened cardboard box on my garage floor. These cars used to seep so much, the old Porsche joke was "It is just marking its territory".

I would be vigilant monitoring oil levels. The shop really cant tell how much oil is coming out, only that some is. If you are not seeing much movement in oil levels between oil changes, I would not worry.

 

I noticed that mine was seeping a few years back while doing an oil change. Not enough to leave marks on the garage floor but the frame under it is oily and covered in dirt that sticks to the oil. I check once in a while and it hasn't gotten worse, so I don't even think about it anymore. Will have to address/disclose when it's time to sell that car, that's the only concern really. Or if I do clutch before I sell the car, will replace then.

 

06 C2S here. My RMS weeps a bit. It's mostly dirt accumulating near the engine/transmission mating point. I saw maybe two drops on the ground ever with the last one being over two years ago. Nothing since. I will not fix it until the clutch goes. I've been saying that for 40K miles now with the clutch still going strong. Save your money until you need to drop the tranny for a real reason. Instead just stay on top of oil levels, consumption rates, and change intervals. It's not worth the $2K to "fix".

 

Thanks guys. I appreciate the advice.

 

Check the plastic underside covers for any oil residue - maybe ask your service guy to remove and take a picture.

 

This is something that can wait until the clutch needs replacement or some other engine-out service.

 

Weepy/Seepy RMS is normal. I get about 3-5 drips per year on my garage floor. Your only chance to keep it at bay is by doing everything else you hear about: Fresh oil and drive the darn car. Usage keeps things flexible/pliable, and burning off water and other contaminants through good old fashioned hard running is always kind to seals.

I had an intermittent oil leak from back there on my car. It would usually only show up after the car had been run a bit hard. I sent pics to a Porsche tech who identified it as seeping RMS. I didn't think so. Sent them to someone else who said it was a drip from the case halves bolts. Evidently, the torque on these is very light and the oil can actually follow the bolt threads and drip from the head.

Simple solution. Remove the bolts one at a time, put some RTV on the threads up near the bolt head, reinstall, tightening to the proper torque. Oil leak has been gone for a year now. Make sure yours isn't this before looking to RMS solutions. Here's a picture where my drips were originating from (see the dirty area).
