Mine was leaking a bit and under warranty. Turned out to be the IMS instead and they replaced it. The RMS seems like a high probability event with a 911. I've had no issues since and about 10k miles later. Ask the shop - doing the RMS is a routine event, probably more common than doing a clutch!

 

The service manager said it's really not common anymore...doesn't see very many of them, especially on the new cars.

I had this happen. They fixed it. End of story.

 

What year is your car? Miles?

J

 

2007 C4. It had 4000 miles at the time.

 

I'd vote to get it fixed. It is under warranty. Your lucky that your local dealer is willing. I've heard that unless it is dripping onto the ground, many dealers won't touch it under warranty. Seems like a bit of B.S. to me to not address the issue, but bravo for your local for taking care of you.

 

Thanks. How many years/miles since it was fixed?

J

 

Thanks for the input. See...there again, a bit more proof that it's not a "serious" issue. If it's not a full blown leak...some view it as a "non-issue". I could see where a dealer wouldn't want to waste time/money on something that isn't a "real" problem. How many makes/models go in for service, have RMS issues that aren't even reported because that's what rear mains do? I'd wager, many. And a bit of proof that my dealer is willing/wanting to take care of me...which is nice .

Ok, here's another question...is there any mod that I could think about while this is being done? Something that makes it more "fun"? Light weight flywheel sounds cool, but I've read that that can cause problems...so I don't know about that. SSK doesn't really seem like something I'd want. Anything else worth considering?

I heard that 997.2, this issue has finally been fixed....so my 2009 C4S should be OK...is this true?

Also, I'd like to understand why not driving the car much makes the RMS worse...I only have 4400 mile on my car since I have a DD as well.

 

As I understand, it's not low mileage which makes it more susceptible, but driving at low rpms. Let it rev and be happy! But I could be wrong...

 

You have this tiny little spot on your face. No biggie you say. Until it becomes a big problem.



Dude, get it fixed. It's not like a door ding. Why this a question? And drive your car more!

It will get worse. If not for you then the second or third or fourth owner.....

 

Don't know that it can be "fixed". Never heard of an engine without a rear main seal, and rear main seals "can" leak.

As for mileage, from what I understand there are two possible causes. Crankcase pressure keeps the seal "sealed". Crankcase pressure comes from running...regularly. Second, seals "dry up" when not regularly lubricated by running...and then begin to leak.

Why the question? See above posts. I can't drive the car to/from work if I wanted to, and I don't always go out after work. I drive the car when I can, and it's usually once a week. There won't be any other owners...I keep every car that I like...and I love this one.

I hear denial. Havn't you ever been to AA, er, had a friend that has? First step is admitting you have a problem.

I'm sure you have a few neighbors that wouldn't mind keeping the seal "lubricated".
