Dude, I don't think your ever clear mine is in the shop for RMS repair now 39K miles
Hey Jeff,
how did you notice the RMS... was it the tell tale oil spot between the 2 tires?
I've heard of RMS issues at less than 5000 and I think over on RennTech one at 65,000. But remember an RMS replacement isn't the end of the world. It happens on all cars...
I see you took my advice
Well, as I have explained before. RMS leaks can be caused by a variety of factors. Making it to 55K miles strongly, strongly suggests that you do not have any issues with your block. A bad block would be the expensive scary repair to face out of warranty. I think that odds are strongly in your favor that you will not face this issue.
The other common cause of RMS leaks I understand is the improper installation of a good seal. Again, making it to 55K miles strongly, strongly suggests that your current seal was not installed incorrectly.
I understand that another common cause of RMS leaks is a defective seal itself. Again, making it to 55K miles suggests that your current seal is not defective.
Can good seals that are installed properly in good blocks go bad? Yes. IMHO, that is the most likely failure you will face. I don't think that anyone here can give you accurate percentages as to the chances you will develop an RMS leak from a good seal installed properly in a good block.
In any event, even if you do subsequently experience an RMS leak, replacement of that seal should not be a big deal. Your block will not be damaged (or it will be covered by the replacement parts installation warranty). The new seal will be installed properly (or it will be covered by the replacement parts installation warranty). The new seal will not be defective (or it will be covered by the replacement parts installation warranty).
For these reasons, IMHO, I wouldn't lose a wink of sleep over RMS issues if I were you . . .
Midnight Rider - Like TD said... possible, not probable. But even if you do get a RMS leak, look at the bright side. You'll get the Senior Citizen discount, 'cuz you'll be over 55(k)!
it can happen anytime on M96s
Don't forget that letting you car sit for months at a time without starting it will also increase the likelihood of a seal leak.
True, forgot to mention that. Driving habits supposedly can have an impact upon whether a non-defective seal installed properly in a non-defective block start leaking. I have heard, although I have no way of confirming, that if a seal starts leaking for this reason you may be able to stop the leak by driving the snot out of the car. The theory is that the seal contracts enough to allow oil to seap past, but that if you drive it hard enough you can get the seal to expand enough to slow or stop the seapage. Again, I have no way personally to verify, I am just passing along what I have heard.
I still don't think it is anything to lose sleep over if you have made it to 55k
It's all part of the Porsche owning experience!
