Personally, I find Porsche's lack of quality on this issue disgusting

I'm no mechanical engineer, but the general concensus is that the turbos are far less prone to leaking because of their tighter, more elaborate seals. Apparently these seals can't be used on the normally asppirated GT cars because internal pressures rise too high.
One would think that this pressure could be relieved by means other than a loose, poorly sealing seal... Can't they use a pressure relief valve or something in conjunction with the firmer sealing turbo seal? The pressure relief valve could eleviate excessive internal pressure without oil leaks and surely wouldn't be difficult to incorporate into the existing crankcase??? Obviously they would need to determine what pressure is too high in order to use an appropriate valve but that should be a no brainer, one would think considering they designed an appropiate seal to leak so frequently...

As I understand it, the 997 cup does leak and many replace the seal with a 996 cup seal and have no issues. Maybe P should consult with some of the better race shops out there.
Yes, same one. Still having a bit of seller's remorse and I haven't even sold it yet. Buyer will have a new engine though! Can't beat that.
I've got too much money in mine to get initial purchase price back. But, overall, I would still buy the RS in a heartbeat. The rock star looks and driving quality well outweighs the rms issues.
I like the cayman to drive as well...drove one on the Hockenheim in Germany last year.
Thanks Frank. I have been a good customer with it...showing up to events with it, car shows they sponsor etc. I think either something else is going on with it, or they have some many problems concerning the rms at this point they need to do some R&D. Also, being in Savannah/Hilton Head area, it is probably the cheapest on shipping back and forth to Germany.
Ha! Heck you really don't need to at Roebling...I never run out of gear. However, in the racecar, I do run out of 2nd at CMP and bump it at one place on that track. I've found that as long as I keep the torque range up in the "goody" range, it doesn't affect my times that much to keep the rpm's a little below the "please shift me" mark. Plus, my car and tranny is a lot happier.

Very interesting to say the least!
My 2007 997 GT3 was in for its fourth RMS in less than 11 months in August and I said either a new engine (wear and tear as a result of repeated removals and replacements) or buy back the car. Result I got the total of my initial purchase price as I was told the new engine would leak also. My car had 3700 miles on it and had been in the shop over 9 weeks in the 11 months of ownership. Would have been far happier with a new engine and the statement "this one may seap oil but we are working the problem and just drive it and your warranty is good".
Instead I have been driving a Cayman S since then (7400 miles in 2.5 months) and a 2009 Carrera S with PDK is on order. Great but not a GT3, although the new Carrera S with PDK is impressive and mine will be here hopefully by Christmas.

Roger now the question is will the new motor be any better leak wise. Now you got me wondering. I have had my RMS fixed once, last January and it started leaking in 300 miles, I just have blown it off since its not a big leak and so far everyone who has taken it back for a fix has had no or little success in fixing it. if your new motor works out then that would be incentive to bring er back and keep pressure on it. I am surprised they went to replacing the motor with out some major bitching, You must be well liked or have friends in high places.

- about 6 months ago, someone posted that Porsche had only 1 gt3 motor in inventory
- either someone beat you to it, they want to keep an extra around, or they are putting the old engine back in production for future warranty repairs
- my 996tt seal continues to hold (knock wood)

Sharky, any more info on the 996tt seal, any crankcase pressure problems?
Keep up the good R&D, porsche otta hire you, tt seals are a lot less money than new engines.

Ever since Porsche hired in Japanese consultants to streamline production in the early 90s, and with the start of the 993 subsequently reduced numbers of supppliers from 900 to 350, they aim to use a bare minimum of different parts. If they could get a way with a single, spring-loaded seal, great! The fact they don't, must have a rational, technical reason behind it.

Roger you get the "Lucky Dog" pass. Lets hope they take your motor back figure it out and come out with some help for the rest of us poor bast)*^'s . Give us a shout at about 2500 miles just to be sure.
