The area around the RMS is now sweating again (not leaking) and I brought my car (996 3.4l C2 MY00) back to the indy to get the seals changed (again) under warranty.

I just talked to a Porsche mechanic in EU and he confirmed that he changed RMS and IMS on some cars several times but it has usually nothing to do with the motor.

I actually told them that they didn't say that my crankshaft was moving/non-centric when they changed it last year, so there's a high probability that the seals are the issue and not the motor as they used the new tool already last time.

Suggestion
Do you have a repair order from the replacement which has the seal part numbers on it?

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.

I got my IMS, RMS and clutch changed last December as the IMS was sweating (the area never really leaked oil). The area around the RMS is now sweating again (not leaking) and I brought my car (996 3.4l C2 MY00) back to the indy to get the seals changed (again) under warranty.
The indy just called and said, it's not leaking, so they do not recommend to get the seals changed. It'll not stop the sweating if we change the seals as they believe the crank shaft is moving, so the ultimate repair would be a new motor.
What do you guys think? Should I insist on having them change the seals again?
Yeap, both: new tool and new seal(s).
I just talked to a Porsche mechanic in EU and he confirmed that he changed RMS and IMS on some cars several times but it has usually nothing to do with the motor. It's sometimes just hard to get it sealed completely.
Actually, some motor are not manufactured properly and Porsche issued a tool to see if the motor at the trans connection point is "out of round" (Not the technical term, hopefully someone else can chime in).
It is my understanding that an engine with this problem will always leak so if the tool show the motor is out of spec they replace the whole motor.

It appears that a go-no-go fixture is used to determine if the seal bore is concentric to the crankshaft. If the variation is .03mm or less you get a replacement seal. If more than .03mm you get a new motor. Now with the new fixture they attempt to slide the tool over the crank and into the seal bore. If the fixture goes in you get a replacement seal. If it does not go in you get a new motor. With the go-no-go fixture the mechanic no longer has to measure with a caliper.
Thank you for your reply and the detailed explanation Ray! I used it when I talked again to the indy this afternoon. They will take the transmission apart and change the seals tomorrow.
I actually told them that they didn't say that my crankshaft was moving/non-centric when they changed it last year, so there's a high probability that the seals are the issue and not the motor as they used the new tool already last time.
I'll keep you posted how the story ends when I get my car back - probably tomorrow night. I bet/hope my crankshaft is still straight.
Btw, the mechanic in EU said that he has seen non centric crankshafts mainly on the very early 996 cars (in EU the first '98 cars). Not too many of the '00 or '01 cars had the issue.
Yeah, sounds like someone wanted $3k to install an engine for you instead of fixing the RMS under their guaranty, I'd take it somewhere else to have the work done. The engine isn['t blown until it's blown, well unless it's under warranty.. lol
nogo guage is opsolete, we use snap guages now to measure at 8 points around the crank, I still have only seen 2 that were out of spec.
it seems most cars that re leak are never driven , how often do you drive the car?
Do you have a repair order from the replacement which has the seal part numbers on it?
see if you can have the old seal
I drive my car about 6k miles/year and usually 1-2 times a week. Sometimes (vacation, winter) it sits 2-3 weeks - never longer. I tracked it at 5 DE events since last RMS/IMS change. Oil change every 3-5k miles (1-2/year).
The invoice from last December's repair shows following part numbers:
996 105 017.02
Intermediate Shaft Seal-N
(IMS)
999 113 490.41
Crankshaft Seal-N
(RMS)
Description: Replaced leaking Rear Main Crank Shaft Seal and Aux Shaft Seal.
I believe the RMS # is wrong (maybe typo on invoice). Shouldn't the correct and latest part-number be 997 101 212.00?
What should I do with- or see on the old seal? Do you think they used an old part?
Thanks, Harold
Hammer!
He told me last night: "Yes, I have this Porsche tool! It did cost me $500!"
So what do I learn? Indys are not too much cheaper than the dealer - stealer but there can be some heartburn after the meal. Only issue is that the dealers here in the DC area don't need (want) business. They already have too much! Way too many Porsche around here!
Got my car back! They changed the RMS (not even sure if they did the IMS as well), put my new AASCO LWFW in and charged me 2 hours labor.
They called me yesterday, telling me that my car is ready ... 3 min. later they call again: "we can't put it into reverse".
Today I called: "What's the status on my car?" They: "Whoever put the short-shifter in, messed up with the cables, so we had to put the center console out and fix it." 2 hours labor
Anyway; I feel that I can agree to idemnify them (partly) for their loss due to the warrenty repair.
The LWFW makes quite a change; will be on the track on the weekend and look forward to see how it works out.
Thanks for the link; I'm signed-up for RennTech - great site!
Btw, the indy still told me when I picked-up my car: "Your crankshaft is surely moving around and you might see the seal sweating again!"
Sounds like a good excuse for them for another potential not sealing seal.
cranks shaft moving around..................i keep hearing that.........................but ive torn down a few engines and never found one with a single loose bolt on the carrier
Thanks Paul! The car runs great and heel and toe is so much easier now (but also much more important to do).
I've been on Shenandoah the past weekend and after some irritation with my new Pirelli P-Zeros on the first day (I think they did need some more break in time), I believe I did really well! You would have been proud of your student - haha! Trackdaze put me in Intermediate (Blue) and I ran solo which was fine as - if I can't get Paul, I don't need an instructor, that tries to convince me to take a differnet line (maybe right for a Mustang but not for a 996)!
