OP glad it wasn't anything worse....
not to go OT too much but since ROCS is here....I've got a similar question....what's the lead time and turn around time for a complete engine rebuild keeping 3.4 or going bigger....99 C2...nothing wrong with it...just approaching higher miles

Jake,
Alan and I had in essence the same conversation you had, we discussed all potential bearing noises and their similarities. In the video it certainly sounded like the death rattle, your direction was appropriate and professional.
In his case the clutch fork was severely bent and was rubbing on the pressure plate. Alan had already decided to undertake the retrofit regardless of it needing it or not. I make sure all our customers know about the potential issue as I don't want fingers pointed in my direction for failing to properly advise them.

Rich,
Glad to see you were able to properly diagnose this and didn't just start throwing parts at the problem.

Our days of advising folks about what they should do are over... Time to finish writing the book on it. Otherwise they can ship their car to us :-)

Jake, you are right, enough time has elapsed though its amazing how many people still don't know about the IMS...

Rich - thanks for spending the time in an attempt to educate. I hope you can understand that the IMS has been bantered about so often that a basic owner/driver like myself gets confused. I am no longer a DIY'er (although I did replace the alternator on my Ford Ranger this afternoon and once upon a time, back in the days of carburation, disc brakes were expected, and computers a distint thought, I spent my time turning wrenches and balancing and blue printing engines for a local shop. But that was many decades ago and these days I want to understand theory but I only trust the trained professionals to touch my cars (the junk trucks I can still handle).

Thanks again - I will be in touch after I retrieve my service records so we will know exactly what was done and when.

I am so very glad this turned out well for the OP, and that he displayed the goodwill to update the thread header.

NOT IMS FAILURE!!

Good man.

i live in nyc, how long would a job like that take on 03 c4 cab with 63k on her

The car is on the rack for 2 days for the procedure, depending on the "while you're in there list" it will dictate how many days we'd actually need it for. We've never had one take longer than a week with add-ons.

Hmmmn, I was thinking of the same thing. According to the maintenance records of the car I purchased (01 C2) a few days ago, Porsche determined that the RMS and IMS seals were leaking in 2007. They replaced the two seals as well as the bolts that go on the IMS flange at that time. The LN retrofit was not done and Im curious to know if, per Standard Operating Procedure, they also checked the IMS bearing and deemed the condition to be acceptable.

ROCS Auto Inc

No tech in his right mind would let a bad IMS bearing slide by...dealer or independent so if they replaced the flange/seal and left the bearing alone is because they deemed the bearing to be solid....However, you can't really tell if the IMS bearing seals (the ones on both sides of the actual bearing) have been compromised and allowing just enough oil into the IMS shaft tube by just removing the flange with the flange seal, only real way to tell is by pulling the bearing out. You see the flange seal will allow oil to seep out of the case whereas compromised IMS seals will allow oil past the ball bearings and into the IMS tube. (see pic on page 3 of this thread).

How much was all of this??

OP: Congrats on your positive outcome !

Although I can can say from the second I heard the rattle in your video, I knew you would be ok.

May I ask, did your clutch job include replacing the flywheel?

Cheers
