I am the 2nd owner of an '01 Turbo and I came to find out that Porsche replaced the engine for the original owner after 6,000 miles because of an "unfixable" oil leak.

it's using more oil that originally, so that may be the cause.

Coverage and how to read this overview

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.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Final decision time in next couple days. Other than potential RMS issues with C4S any thing else I need to be aware of?

POST 2Original post

Despite what you read on this board, I'm reasonably confident that the RMS issue has gone away on 2003 and later cars, probably even 2002 cars.

POST 3Original post

No, it has not gone away, but it has been blown out of proportion thanks to the Internet. It is a non-issue to me.

POST 4Original post

Blown out of proportion - you've got to be kidding. Porsche has a fault in their manufacturing process for which they are not owning up to in public. Talk to some of the folks over on the Porsche Pete's Boxster Board that are being told the repair is on their nickel because they are out of warranty. I think that we are just starting to see the tip of the iceberg as more and more cars go past their warranty period and develop an RMS leak. That's when I think the s*** is really going to hit the fan. It's a definite issue for me.

POST 6Original post

I have an '03 C4s with delivery in Feb. I have to say that this is by far the most reliable car I have ever owned. In the first year and a few months of ownership, it's only needed an oil change. Can't say the same about my Audi S4 or even my old Acura. Not a single drop of oil leaked.

POST 7Original post

My '03 C4s had a leaking RMS at 4k miles. I was inconvenience for a day, while the dealer replaced the seal. Really no big deal, unless of course it happens again.

POST 8Original post

I think i just found an rms leak on my 2003 C4S. it's using more oil that originally, so that may be the cause. i'm no mechanic, but i'd think that none of these cars should have rms problems...i've never had a clutch, transmission, engine problem with any car i've ever owned in over 750,000 miles and 26 years....then i buy a $90,000 car and people on here keep trying to justify why porsche quality sucks on this rms issue.

POST 9Original post

02 box S no issue 02 C2, no issue 02C4S, many RMS RMS is not biggie. they replaced it with new one and it was fine.

POST 10Original post

I am the 2nd owner of an '01 Turbo and I came to find out that Porsche replaced the engine for the original owner after 6,000 miles because of an "unfixable" oil leak. At 18,000 miles I had a blown diverter valve and a problem with the MAF. Those were the major issues, Minor ones included little things like a problem with my PCM I (which the dealer replaced), and a loose ash tray. While it is very concerning that the car needed a new engine in 6,000 miles, it is good to know that Porsche is willing to go to that extreme to fix a problem.
