    The lift leaks a little. lifting cylinder does leak a little. it seems today the lift function has gotten weak. at times i try to lift and it only moves a small bit. keep trying and it will eventually go up.

    A bit of seeping around the gland nut of the lift ram is not unusual or serious. The seal is easy to replace or depending on the plow it may be a compression seal and you can just tighten it to make it seal. Not going up reliably has nothing to do with the leak unless your fluid is way low. You need to check pump pressure first to see if there is pressure for the valves to work with. Tell us what kind of plow you have and we can tell you how to do a pressure test. You can test before the valves and after. You probably have a worn out pump or your pressure relief valve is set too low, that happens as plows get old and the springs get weak.

    How about moisture in the system . Seems like ya got two threads going on the same problem. Oil doesnt cause rust. If the weather has been cold there , maybe its iced up inside. First thing I do when I have plow trouble is take it in my shop where its warm, let it sit for a bit and start from there.

    no shop, but since its leaking, it is possible for it to have moisture in it. once i get it appart i can know much more about it. i plan on getting the rebuild kit monday i hope.

    I agree, if your area is cold enough to freeze moisture trapped in the pump this will stop it from moving up. If you haven't changed the fluid in a while it would be a good idea to get it into a warm shop (so the ice melts) and purge the fluid when you rebuild the ram.
