Reported cause
This problem is indigenous to the 996 and 986 engines and even a few in the 996 TT engines.
Leading evidence: 'indigenous' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'indigenous' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace does it totally solve the problem' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

And if the seal is repaired or the engine replaced does it totally solve the problem?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Took them two tries, but Dodge fixed it and delivered it to my home.

WHere in Albany are you?? I am from Bethlehem, lived there for about 10 years....just moved down here with my family 2 years ago. Just curious, so far you are the 2nd person I found on a forum from Albany...small world...

KMO,
I have an '03 C2 Coupe that sprung a leak at about 6,000 miles. I've got 9,500 miles now and the fix has held so far. However, after losing an engine at 20,000 miles on my '99 and experiencing a myriad of other problems with that car, I no longer believe my '99 was an unlucky aberration for Porsche. I'm expecting another leak any time now.
I have an '04 996 Cab on order and I have have become very concerned about all the reports of RMS problems. Does anyone have info on what % of 996's are affected? And if the seal is repaired or the engine replaced does it totally solve the problem?
It's the no charge ticking time bomb option that comes with every Porsche 6 cyl engine.
If it leaks and is repaired it can leak again, and if the engine is replaced it can leak as well, and be repaired.
That's not quite correct.
It comes with 996 C2/C4 and boxter engines. I have also heard it being
a problem with 993s but I don't think it's a problem with all Porsche flat 6 engines. Certainly the 996 Turbo doesn't seem to see this problem.
The second part of your comment is correct ;-)
after my 99 RMS was fixed along with the cam covers and the spark plug rings it never leaked again in 30k miles, but then i traded it in for a 2003 so i can't say that it would never leak again, but it did seemingly fix it

Just thought I would post something new for a change
Rennlist sponsor Dr Ing. Porsche can you hear us?
If so can you please tell us if you fixed this problem yet?
Will it be a feature of the 997?
I still love this car
Waz you are a hero. Just when I feel like crying you posted that mule and I just fell off me chair
But I tell you today is a bad day in the eyes of a Pcar driver.
So, this morning, I posted out my neurotic RMS Rms rmS posting
cos all I am seeing is RMS this and RMS that not to mention my own
RMS issue which was fixed a few weeks back. Anyway........
I take my car to Tech9 this arvo to have some tailpipes fitted. They
hoisted the car up and the first thing the tech said is "hey I see your RMS is
leaking". HOLY SUFFERIN SACKERTASH. Not F*k'n possible! It's just been done by my local Porsche dealer........So now I am back to square one.

In between my two Porsches, a 95 993 and a 2003 C4S, I bought a brand new Viper, 2002 GTS,ACR. Got it home, with 47 miles on it.
Next day huge RMS leak oil all over garage floor. Took them two tries, but Dodge fixed it and delivered it to my home. Never had a problem after that.
It's not just Porsche is my point. The Viper stickered at $82,000, I think I paid $72,000 so it's on expensive cars too.
There seem to be some fundamental laws of physics that make it inherently difficult to come up with an oil tight seal around the spinning crank shaft. If its too tight the friction would presumably heat up and burn of the seal, but if its too loose it will leak.
If you look at any parking lot, every stall has an oil spot under the RMS point and if you look at any highway, there is an oil slick down the middle of the tire tracks. At my office even the reserved parking area, which has pretty much only newer cars, has oil spots in all the stalls.
I wonder if there is any chance at all that Porsche rear main seals are really no, or not much, worse than any other brand?
I agree with you, I was thinking the same thing.
Lexus has great statistics as far as low incidence of *reported* problems. But everytime I've ridden in a Lexus or other high end Japanese car, I notice problems (vibrations, noises, broken functions, etc) that the owner is just oblivious to. Maybe Porsche owners are just perfectionists? I know I am.
Its funny that you mention Lexus. My wife's 2002 LX470 which cost more than a base 996 developed an oil leak within 20k miles. It took them a week to fix it and they never told her what it was. Hmmm could it have been...?
Yes every car probably has the problem but on a �70,000 car I expect better. When it happens to your car then come tell me your still happy
with the quality.
No matter, this car is still my little baby and I love her
The 993 does not suffer from a RMS problem like the 996. This is a rare problem for the 993. Most oil leaks on a 993 are a result of a leaking valve cover gaskets, an easy fix that any DIYer can do. Now CEL and carbon build up in the secondary air injectors...that seems to a problem that is developing with the 993.
Is this true?
If so, what makes the 996 more susceptible to the RMS problem than the 993?
What's your guess as to the percentage of 996's with a RMS leak? Is it the same percentage of Boxsters?
I'm planning on buying a Porsche in the Feb. - April time frame and this RMS thing has got me concerned.

I've been reading about leaks ont this board for a while now... what are the signs of an RMS leak vs a broken coolant bottle/hose? In an RMS leak will you see coolant on the ground or OIL or a combo?
Brian (bet) is right,......
The 993's and their predecessors do not have RMS issues unless a tech installed one incorrectly at rebuild time.
This problem is indigenous to the 996 and 986 engines and even a few in the 996 TT engines. I'd venture that either Porsche's current manufacturing operations has a QC problem or a seal vendor has supplied a large batch of defective parts.
To their credit, Porsche has been very good about warranty repairs thus far.
c70Pete:
You'll see some oil on the floor under the car in the center between the engine and tranny if you have the RMS problem.
