Reported cause
Porsche had our dealer put dye in the oil at 57k milles just to make sure it was the seal.

Leading evidence: 'seal' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'seal' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Repair $2k, clutch every 50k miles, $3.5k)' (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.

Reported cause
Here in the UK, the RMS problem is so prevelent that many IPCs are competing against each other in price and it's become an advertised service in the mags.

30k, 38k, 49k, 50k, and it leaked again at 57k so Porsche replaced his engine last week.

When my RMS was replaced (after 7K miles on a '04 Carrera), they also replaced the intermediate shaft seal.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Suggestion
I'd like to know if any cars have sprung an RMS leak after repair, which (i) passed the concentricity test, (ii) were repaired with the latest updated service tool (apparently there are several versions), and (iii) had the casing bolts replaced with proper ones (ie, not re-used original according to the latest technical service bulletin.

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.

After reading so much about RMS on this site, I asked my dealer about the prevalence of the problem.
The service advisor told me that the problem effected Boxters far more than 911s. Also, the '03 & '04 911s did not suffer from the RMS issue.
Is this true, or just dealer BS?
the RMS issues are a result of poor engine casing design for all boxsters, and 996's (99-04 911's).
the only exceptions are the 911 turbos, GT2, and GT3 which use a modified version of the 993's engine casing in order to achieve dry-sump lubrication.
The shop manager at the local dealer told me that he does rms repairs on about 10 boxsters a year, but has not done one 996 yet. He has always been very candid with me, especially about the set of problems I can expect with my M5 (VANOS repair $2k, clutch every 50k miles, $3.5k).
Believe me, even with RMS, owning a 996 is relatively inexpensive compared to a number of other high performance cars...including BMW, Ferrari, and Aston Martin.

No doubt it may be relatively inexpensive compared to some but it doesn't take away the fact that the RMS problem in these cars is a manufacturing flaw that needs to be addressed by the manufacturer. Consider also that my first RMS was done in November last year, since then it's had 3 more (making it 4) and it now needs to be replaced again. So, in less than 9 months I am looking at 5 RMS'. Is this acceptable? I don't think so.
I find that many OPC shops say that they don't see many RMS problems but go to an IPC and you will get a different answer. Here in the UK, the RMS problem is so prevelent that many IPCs are competing against each other in price and it's become an advertised service in the mags. As soon as the PCGB boxster RMS survey results are published (based on about 1000 owners with about 650 respondents), we will know the true scale of things.
uberxy- 2002 c2 22k rms x 4
My last trip in they were putting in the 4th RMS in another 2002 996. It seems that the total % of afflicted cars is low, many that are good to go with a single repair. Then there is a subset of repeaters of which I am a member.
For me, the dealer's service has made this a relative stress free dance. Barrier in Bellevue Washington gets me in as fast as I like and the repair is complete by the next day. Cost me some time but no money.
What I'd really like to know is this:

A local Boxster had 4 seal replacements. 30k, 38k, 49k, 50k, and it leaked again at 57k so Porsche replaced his engine last week. I am not sure about the first 2 replacements, but the last 2 passed the concentricity test with the tool. The owner was at our work on cars day on Saturday and showed us his new engine.
The replacement crankcase bolts are for when you have an oil leak from from the crankcase bolt holes. His car was not leaking from there.
Tool Pants, could you clarify that comment you made about the boxster with the 4 replacement RMSs and then a new engine....was the replacement engine a freebie from Porsche and was the car out of warranty?
We have a less generous warranty in UK, I think 2 years and then you can pay for a very limited amount of mechanical insurance which only covers major failures but not oil seals.
Since 1999 the warranty has been 4 years or 50k miles, whichever comes first. 1997-1999 was 2 years. US Boxster numbers.
Jean's car was out of warranty for a few months when the engine was replaced last week - no charge. Porsche had our dealer put dye in the oil at 57k milles just to make sure it was the seal. It was. I forgot, he also had the intermediate shaft seal replaced with the 3rd replacement.
I just hope his replacement engine does not leak. When Jean's comes to our work on cars events I would have to jack the car up and look for oil. When he found a leak on his own he would take pictures and email them to me. Gets old fast.
This is Jean's new engine.
THIS PROBLEM IS PREVELENT IN ALL 996'S AND BOXSTERS,AND THE NEW MEASUREMENT TOOL IS NOT MADE CORRECTLY.ASK THE MECHANIC TO DO A MANUAL MEASUREMENT USING A SNAP GAUGE AND MICROMETER.
When my RMS was replaced (after 7K miles on a '04 Carrera), they also replaced the intermediate shaft seal. For the RMS, the dealer said they always measure with the special tool, and also with a good old fashioned feeler gauge, and my engine passed both. They also said they always add dye to the oil after a RMS repair.
