RMS and 987 Boxster

Recommended Posts

Hi,

I have been searching all over the net on all sorts of porsche sites but i cant find any useful information. The 987 Boxster has been out since 05 and it has already been 2 years almost. My major concern like most who own and want to own a Boxster is its reliability. The major problem that plagued most 986 were the RMS problem. I would like to ask owners of the 987 Boxster to reply in this thread with their experience, especially if they have had RMS issues. Please reply with your YEAR, MODEL, AND ENGINE.

Thankyou,

Tony

I had the RMS replaced last week on my 987S-05. Otherwise it has been very reliable.

I have had a 987 base since June 2005, now with 21,000 miles. The only problem I have had is a broken elastic band in the convertible top, and two nails that I mannged to pick up.

A few of the very early 987s came with the old style seal and a few have leaked. The new PTFE seal so far has been perfect, I've yet to hear a single one leak. Having said that, I wouldnt be afraid of an early 987 if its the color combo you want. Even if the rear main does leak, the dealer will install the new seal and you'll be good to go.

Thankyou for your reply. Even if the dealer would repair/replace the RMS problem i would still be weary for future ongoing repairs, such as what some expereinced in the 986s. I would kill myself if i had mulitple RMS in a year! :wacko: But if the new seal was used for the RMS problem in early 987s as in later 987s as you described, that would be very good news!

just posted my predicament on 986forum.. i bought couple weeks ago a 2005 Boxster S 2.3L 987... the engine had some whirling/cranking noise. took it to dealer in hong kong.. and they said they need to replace a new engine! i was really upset because i had a 1998 base model 986, 70K KMS and 9 year old ...NO ISSUES.

i have yet to see the formal diagnosis and report. the only thing to thank-god is the car is under warranty and i think i dont have to pay anything. heard from other members it may be related to intermediate-shaft failure.

HK your a bit off topic with your post. intermediate shaft failure isn't caused by an RMS leak , more likely a batch of defective parts from the factory , therefore likely to be the exception rather than the norm. Please keep the forum updated with the progress , but don't worry that its a common or usual problem because it isn't.The RMS leak referred to , relates to a known and re occuring problem seen with the 986/ 996 engines, which now seems to be improved on the 987/997. The gearbox was removed on my 987s which is a september 2004 build with 24k (miles) on the clock. No sign of any issue with the RMS , so it was decided not to change it. The work carried out was to replace the dual mass flywheel and clutch which had started to slip occasionally.

In reference to the 'build date'....the tag on my '05 base 987 says 05/05. Is that referencing May 5, 2005...or a random date in May of 2005?

The build date is just month and year.

Would there have been any notations as to VIN sequence when the 'new style' RMS was installed? Since the factory only dated the manufacture of the vehicle by month/year this might be a reasonable assumption? I'm not losing any sleep over the issue, but am just curious what side of the fence my 987 is on for future reference.
