As mentioned in an unrelated thread, the clutch cylinder is leaking on my 2000 S10 4.3L. This is one of those things that can be managed by carrying a bottle of brake fluid and topping off when needed.

I am debating about keeping this truck long term so wasn’t wanting to spend $1000 to have the entire clutch replaced. Unfortunately the cylinder is in the bell housing so the engine and transmission have to come apart and at that time you just replace the entire clutch set.

This seems to be more of a problem in cooler temps. Is there any kind of product that could slow down or stop this for a bit? I know it would be a band-aid but figure it might help in the short term while I decide if I want to keep the truck.
