RMS Question

[Ed Hess]

I've included some names of people for anyone in SE PA. I have some
RMS stuff to ask about. When I took my 2003 2.7 in to be inspected a
couple of weeks ago, Paul at Performance Automotive told me it was starting to
seep a little oil near the RMS. I had taken it to Brandywine and had the RMS
replaced at 44K and then again to Rosen where it was replaced at 47K while it was still under warranty. It now has 49.5K miles and is out of the Porsche warranty period. I took it back to Rosen yesterday and they looked at and
saw the seep but said Porsche does not approve fixing it unless it is
dripping and there is noticeable oil being spashed behind it. Bill
at Rosen told me 99 out of 100 boxsters would have as much seepage as
mine and 911s as well. He said if they fixed it again it might not be
as tight as it is now, but agreed to take another look at it in a couple
of months to see if it has gotten any worse. I'm not too worried about
it as I bought a major mech. warranty from warranty direct that covers
seals, but I am wondering if I should escalate this to 1-800-PORSCHE and
just say this is unacceptable. Any comments or feedback is appreciated.

Thanks.

I would have escalated even after the SECOND rms issue was discovered only 3k miles after the first one. What happened to you is unacceptable. And I wouldn't even bother making claims on the aftermarket warranty. You are still experiencing the problem that started and was dealth with while still under Porsche warranty. Warranty fixes should also have a warranty on them, otherwise they're not fixes at all -- your case in point.

I have to agree with what these guys are saying, if some one replaced your RMS with a new one, they should have some type of garuntee on the work that was done.

On another note, my machanic that replaced mine said that the Porsche uses a CASTING process that is done my a machine that leaves the SURFACE with a ROUGH finish. That is the real cause of the problem. If you have ever seen a casted alluminum block up close, you can see what I am talking about. This is why the seal DOES NOT work properly. In many cases my mechanic would recomend RE-SURFACING, the area where the seals are made to create a BETTER seal between the parts. Porsche is well aware of this because most of the newer models like the 987 from 2005 and up use a newer process that does not leave a rough surface which so far has cured the problem. That's just my 2 cents.

Hi,

Only partly true. The newer models do not have a different block. Porsche, to save money on Production Costs, adopted a Casting technique invented by Audi which eliminated the need for post-cast machining, there is no traditional center-bore machining at all. This results in a % of Blocks where the opening for the Crank is not properly centered. This is one cause of RMS - the Seal can never be properly seated to begin with.

The other involves the way the Crank is cradled. This design allows the Crank to meander slightly off it's centerline, and this is what abrades the Seal leading to premature failure.

All variants of the M96 engine suffer this and to a high extent. At least 25% from anecdotal sources and if you believe Scott Slausen at PCA Tech Committe, he states that all M96 engines will have this problem. ..

Happy Motoring!... Jim'99

Thanks for making more sense out of what I was trying to say. So is it true that the newer models have fixed this problem? I heard that it is no longer an issue with the 987 models.
