Thanks for the tips, Marty. I have used a sleeve on my Corvette front main seal, since I was too cheap to replace a damper that had only about 5K miles on it. I will check on the condition of the sealing surface on the flywheel... I know for a fact that there are no grooves that can catch a fingernail, but I'm not sure whether there is any pitting. I didn't realize that sleeving was an option for this part.

An alternative to a sleeve, is to check the width of the wear on flywheel. I had good luck pressing the seal in an extra 2mm or so - allowing the seal to wear on a fresh area of the flywheel.
Not a long-term fix, but it worked. Enjoy! |

I looked at the flywheel again last night. There are two noticeable wear areas where it rides against the seal. I've been referred to Peak Performance VW in Seabrook, MD. I'm going to take the flywheel to them and see whether they recommend sleeving or polishing.

My orange seal. I took about 6 pictures and this was the only one that came out in focus. It's made by Victor Reinz, and the box had a label that reads "Made in Germany."

HPH DOES do mail order, I just got a brown seal from pelican too though... made be elring or something like that, says made in germany too.. I don't think mine was leaking until I pulled the engine and checked the free-end play... that shouldn't have F'd it up though... |

The Viton seal is all I use and stock, but about 25% of them have too small of an OD creating fitting issues, as a leak can come from around the seal... We measure them and send the junk back.
Flywheels that have grooved surfaces eat seals for breakfast. |

Jake,
1. How would you define "grooved?" If you can feel it with your fingernail, no matter how slight, it's a groove? There are no less than 2 of these smooth but very very slight indentations on the flywheel that came out of Babydoll. (I don't know what the other one looks like, but I can get it out of my garage attic and inspect it thoroughly.) Would a flywheel with such a grooved surface then be a candidate for sleeving, assuming that it is in otherwise good shape? 2. I'm pretty sure that my orange seal says Viton on it. |
