I will be replacing my clutch and torque tube this spring. My '85 has 130,000 miles on her.

When I get the clutch out, if I find the RMS is dry, do I just leave it alone or risk a leak by replacing it? Found lots of posts where this happened.

For those who have more than 170,000 miles on your vehicles, do any of you have the original RMS that is still not leaking?

Searched this venue and found quite a few where the brand of the RMS was the leaking issue when a replacement was done. Has this issue been resolved?

I had north of 160k when i did mine. It was dry but age, miles and boost said i better change it while im in there. No issues 40k later.

i did fk one seal up installing it...cant recall if it was the front of back though.

Replace it. And get the Porsche version. Easier to install.

I have a memory that Greg Brown had a better version, though that might have been the front crank seal.

Call Roger and get the Elring version. The Porsche seal does not have full ribs on the outer edge.

I believe it’s this one. Got mine from Roger.

Yes, I would definitely replace it.

Also, next time you do your timing belt, replace the front seal too.

The Forgotten On

I always assumed you should replace an RMS whenever you replace the clutch (within reason).

The leaking issue was caused by seals that only have the outer ribbing go half way up the seal.

Elring has their seal with ribbing going the entire height of the seal and they don't leak, same for their front seal.

My 89 has its original RMS and has in excess of 217k miles on it, but I would have done the job if it wasn't an auto. Doing the seals on them is a bit more... involved.
