Question IMS or RMS? Any way to tell?

First off, thanks in advance - this forum's information has been incredibly helpful as I learned about 996s before pulling the trigger at the car this week. I'm new to P-cars (just graduated from Mustangs) and have an older S6 daily driver.

Is there any way to tell by the leak or color if this is an RMS (or worse, IMS) about to go? Car 2003 996 w/ 27K miles, purchased this week.

I will be doing the LNE retrofit but was hoping to drive her for the next couple months (2k miles max) until I save up the money for the retrofit.

Any way to tell how safe I am waiting a couple months???

Thanks for using this thread. You need to remove the transmission to see whether it's RMS or IMS or both. No way to tell from just your pics. Note IMS leak could be a precurser of IMSB failure. If You plan to address it anyway, I think it makes more sense not to drive it till you can inspect the bearing. Why take the risks.

I do not wish to scare anyone as I purchased a 997.1 2005 m97 Carrera S and have some constructive criticism. I changed the motor oil every 4k miles of the 20k ownership I had with the car.

first issue I had was a leaking rms - this happened twice within 20k miles.

I though I was safe and sound when I creeped into 55k miles with respect to the IMS, then all of a sudden backing out of my garage I feel a thud. shut down the engine look around the back and see a pool of oil.

sell these m96 m97 cars and buy either a 911 with a DFI or Metzger motor. I know that they are a lot more expensive. I would either recommend you buy an aftermarket warranty to cover such events.

I am amazed by the number of "experts" that do not know how to spell Mezger.

Recommending that EVERYONE sells their M96-powered 911 and spend a great deal more money to purchase a car with a different engine isn't constructive criticism - it's unrealistic advice. It seems like you were aware of the IMSB issue but chose to not retrofit your (likely) single-row car. It sucks that your car turned out to be one of "those" cars - but there were steps you could have taken to prevent it that are less costly than acquiring a 991 or a Mezger car.

Regardless of the fact that I don't like the advice, I do feel for anyone whose engine dies unexpectedly - that sucks, and I'm sorry to hear it. Based on your signature, you were able to heed your own advice and get a Turbo - which is awesome. It must be a blast...

That engine is filthy for 27,000 miles. In fact, its filthy for any mileage. Dropping the engine ASAP is the best thing you can do, so sounds like you got it covered. I wouldn't wait if I were you.

But if everyone takes your advice, the people that buy the m96, m97's will read this and immediately sell their new m96 m97's and the people that buy those will immediately sell their m96 m97's....

I bought an '05 with approximately 20K. Two years later at around 32K when the CPO expired I had the LN IMSB installed along with a clutch (the pedal was very hard to push, the previous owner probably didn't know how to drive a stick properly), and at the same time bought a 6 year bumper-to-bumper aftermarket warranty. Now 4 1/2 years later at 62K the IMS is still holding up, and the aftermarket warranty has almost paid for itself in various "minor" repairs (shifter cables, water pump, oil pressure sending unit, coil packs, rear strut mount, motor mounts and a few others I'm forgetting at the moment). I still have 1 1/2 years or 12K miles left on the warranty.

For half (or less) than what it would cost me to sell up to a 997.2 or 997.1 GT3 or TT I could put a remanufactured engine in my car. The chance of me needing to spend $25K on a new engine is definitely less than the chance a newer car will depreciate at least $25K...because the latter is a certainty.

Changing out the IMSB has given me the freedom to worry about bore scoring

If you want confidence just shop the Internet
or autotrader for 996's, refine the search for
High mileage.
Contact the sellers and you will learn the owners
Just put 120,000 miles on the car and don't know what a RMS is.
Lots of high mileage original cars out there

Just picked up an 02 C2 with approx 100k Miles, has the replacement LN bearing and I'm pretty confident I wont have any issues.

Hi all
Newby here, considering my first 996 purchase.
I found an '02 996 in the Dallas area that I like a lot.
It's a 36K car in very nice shape.
The description in the advertisement clearly states LN IMS Bearing.
An e-mail with one of the sales people confirms this was done.
When i asked for a copy of the shop order the work was done on, I was sent the attached:
1) VIN on the shop order matches VIN in the ad and on the included Carfax.
2) I see comment '..........requests replace intermediate shaft seal' and the first 2 parts noted as a sealing ring and housing.
3) Is this the IMS bearing?
4) If so, any ideas on how this could have been done at $0 on a car clearly out of warranty.
5) Should I expect to see something clearly referencing an L&N Eng IMS bearing?

Thanks in advance
Anyone fell free to PM me with guidance/assistance on this.

That invoice only shows the car had its RMS and IMS flange seal done but not the bearing (IMSB) itself. I would also expect LN bearing listed on the invoice if that was the case. Note not all dealers are willing to perform aftermarket IMSB retrofit. The "0" charges maybe because the costs were covered by an aftermarket warranty. The invoice said internal pay so maybe some insider paid.

Ahsai - should I expect to see this specific work listed on the CarFax?
There is an entry in the time frame, but it does not mention the seal work.

Doesn't the LN bearing come with the flange? I have my original flange but was not charged for a separate one when mine was done.

As said in another thread, if there is no proof then it wasn't done as far as your concerned.

Boggles my mind why they would go that far and not do the bearing though. Maybe it's a replacement engine and has a captured bearing?

Unlikely. Carfax is good to confirm issues with the car but not good to prove the car has no issues beyond doubts because negative entries could be missing (e.g., accidents, bodywork, etc.).

Yes, the LN IMSB retrofit kit comes with a custom flange. That's another indication it's unlikely the LN kit was used because the part list contains the stock IMSB flange and its seal (parts 13 and 39 here)

They're now admitting that the bearing probably wasn't replaced.
I'm wondering if any of this work was done.
As Gnat mentions above, why would you go this far and not change the bearing?
I'm questioning the invoice itself - all of this work and parts at $0 on a 12 year old out of warranty car with no signatures at the bottom. Just doesn't look right to me.
