Hi!
Any hyd cylinder that is leaking should be rebuilt, as contamination of the entire hydraulic system will eventullay occur and cause lots more damage.

The US imports more oil from Canada than any other country.
My comment was not meant to be political. Canada is #1 and followed by Mexico for exports to US.
Normally its up to you and how much your prepared to pay for oil, but rule of thumb is oil leaking out of the head is bleeding pass the head seals, as long as the wiper seal is still intact then your ok and do it when it gets annoying, but if the wiper seal is damaged or gone all together then get it done asap as you risk the chance of contamination being draw into the head seals and possibly the hydraulic system particularly if it the bucket cylinder.
If the head seal looks okay.. no chips or cracks does that mean it is okay and I can wait a bit longer to reseal a bit longer? Or is this pushing it?
