Glen, you probably have a leaky cylinder and along w that air has gotten in the top hyd system. Verify by locating source of leaky fluid, suspect cyl or line immediately above that, and see how diff it is to remove. It'll be tough to find clear fluid, I would need my headlight, glasses, and a magnifying glass and clean tissues to learn as much as I could, but Im approaching geezer status and need to see clearly w lots of light.
I would not be a fan of just fixing one cyl, there may be impurities in entire sys and the pump. I read where the charge was 250 to rebuild all the cyls.
Once cylinders are secure you can bleed pump sys and get air out.
Me, ...... I would think seriously about raising the top manually. It does require a 10 mm open end wrench and an allen wrench, but I have raised & lowered my top manually and its feasable, but much less sexy at the drive in.
