Reusing old oil sight glass

[Guest]

I am polishing my cases and I removed the oil window from the clutch cover and I am just wondering what the chances are of developing a leak if I try to reuse the old sight glass. The glass itself cleaned right up with acetone and the rubber seems to be ok so I'd rather not spend another $20 if I don't have to.

I saw someone posted about using wintergreen oil to rejuvenate old carb boots. Would this work for the sight glass? Or should I just clean it up, put it in and hope for the best?

When I was a Madura owner one of the upgrades was to use a watch crystal in the clutch window- If you use a high temp oil/gas resistant sealant you should be fine. I know Marvel Mystery Oil with rejuvenate rubber really well.

Little smear of Ultra Black RTV around the seal and insert it...degrease well with some laquer thinner or something that will leave it oil free and no residue. Maybe a very thin wipe around the inside as well. Then trim it nicely after dryiing over night.

Give it a try, no big deal if it leaks. Not like you have to split the cases or anything to fix it.

Yea that was the other option. I really doubt it is going to leak going that route.

And like tkent said, no big deal if it does. It will have a brand new gasket on the cover so if I have to take it apart again it's no problem.
