RMS on 2010 GT3
Hello all - I sent a note to Porsche asking whether they had done anything to try to rectify the numerous complaints regarding the RMS on the GT3. Their answer is below. My experience with 3 911s (6GT3, 6C2, 7C2S) supports their statement regarding driving daily. My 6GT3 and 6C2 were not DD and both had RMS leaks. My 7C2S is a DD and has never had a problem. All were also track cars.
==============
Please be advised that GT3 engines have a design which is unique from other 911’s because of it’s exposure to very high RPM’s. The rear main seal of these engines is held tight by a vacuum created inside the engine block. If the vehicle is not used for prolonged periods of time this vacuum pressure may decrease allowing a small amount of oil to seep past the seal. Due to this special design, oil seepage can occur in GT3 vehicles that are not driven on a regular basis.
Your warranty manual indicates that your a customer's responsibility for normal vehicle use is for the vehicle to be driven daily over a distance of several miles. Your vehicle was designed with the assumption that it would be used within these guidelines. If it is not, you may experience some oil seepage; however, this is not a defect in the vehicle but simply a result of lack of use."
To answer your question directly - ("On Rennlist there are an incredible amount of complaints about RMS leaks on the 997 GT3. What has Porsche done to rectify this situation on the 2010 GT3?" )
Oil seepage is considered normal, as outlined above, and is not a defect. However, the 2010 model year GT3 has a different engine configuration and design than prior model year GT3's, which will further minimize and may completely eliminate seepage that results from lack of use. This is a matter of making design changes and updates, not manufacturing defect corrections.

if 2010 gt3 engines are of 964/gt1 design... then they did admit to design flaw in their statement "This is a matter of making design changes and updates, not manufacturing defect corrections."
am I wrong???

I'm astonished to read this. My (german) manual says nothing like this. Actually I'd assume that a daily drive over a (short) distance of "several miles" only won't be good for any engine, let alone a high performance engine.

By the way in the four months I had a '08 Cayman s, while awaiting my '09 C2S (Porsche bought back the GT3)I put 8600 fun miles on it with no leaks and so far the '09 C2S is dry and a blast to drive. To bad Porsche NA doesn't just come out with a letter saying !. Yes it leaks a little, 2 continue to drive your car assuming the leak doesn't increase and yes your warranty will stay in force ie ignore the caution on page 85 of the owners manual. I think that small and inexpensive step on their part would satisfy the majority of owners. I know if they had sent such an honest letter to me i would still have the Gt3..... well maybe and only if I had not driven the new C2S. I have an '83 Sc as a track car so things are in perspective.

I can only speak for my own car, which is driven roughly once in every seven days for the past year-and-a-half. It now has 22,600 km and is completely dry. There are some people here who have similar mileages and are on their third RMS. Unless they are running their car in some bizarre way, there seems to be no good explanation.
In the past when this subject was discussed, I put forth an idea whether or not it has something to do with the way the car has been run-in, but none of the affected owners has picked up on this thought.

FWIW My RS leaked and then track season started and it got driven a lot, the leak stopped dead.
