Hi guys, I am building a dump bed for a pick-up with a power up gravity down system and I am using a regular cylinder. I will be installing a breather with a filter on the top port but was wondering if I can pour some oil in there to protect against corrosion. I want to pour in a small quantity, extend the ram and whatever stays in will prevent rust. Is that a good idea or will it plug the breather on the long run. Or maybe I can periodically remove the breather and spray some lubricant in there?
