Most likely the dealer only replaced the IMS flange seal which is standard protocol for a dealer.

Since day #1 (meaning the very first IMSB ever installed, done at my shop) all LN IMS bearings have used an O ring to seal the ID of the flange to the center stud.

What are the chances that they replaced the ims with a LN retro fit?

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

I had a leak, so I dropped the trans and seems that it's the IMS seal. I called the dealership that serviced the car before I bought it and they said they replaced clutch, ims and rms at 64k miles. Car is at 72k now. What are the chances that they replaced the ims with a LN retro fit? Also curious if the pp or flywheel look ok. Clutch is 8.44mm thick. Hoping that I can just replace the ims seal.

POST 2Original post

I think I would ask for the proof of what they replaced. Looks like they f##$% up. You got it this far. Keep going, the rest is easy.

POST 3Original post

Most likely the dealer only replaced the IMS flange seal which is standard protocol for a dealer.

POST 4 / ORIGINAL POSTEROriginal post

After reading more, it seems that oil leaking from this is bad because that means the seals on the bearing itself is gone allowing oil to pass through? Unless i'm over thinking it. I'd like that have a reason not to use the 1000 dollar parts i've already ordered.

POST 5Original post

That engine has already been retrofitted. Thats an LN IMSB flange. I can spot one from 20 yards away. Looks like its leaking at the nut, my guess is they botched the install by compromising the O ring in the IMS flange ID when installing it.

POST 6 / ORIGINAL POSTEROriginal post

So what should I do? Install the new oring from my LN kit?

POST 7Original post

Pull the flange off and find the leak.. You must follow the same procedure as an IMS Retrofit to do this, else the timing will be compromised.

POST 8 / ORIGINAL POSTEROriginal post

Is this the LN bearing? Just making sure, since the LN bearing I bought looks a little different that this one. Seems there wasn't an o ring installed.

POST 9Original post

Since day #1 (meaning the very first IMSB ever installed, done at my shop) all LN IMS bearings have used an O ring to seal the ID of the flange to the center stud. If its not there, you will have a leak.
