    It sounds like you have a leak in the line or fittings to the lift cylinder.

    Oops, I should have realized it was a Snoway since it's in this forum. I just list "New Posts" and apparently missed looking to see where it is. Sorry, but can't help much with Snoway. I was going to suggest a leaking lift ram seal, but don't know if that would apply.

    Per a friend SnoWay Tech at a local dealer: Check for a "back pressure relief valve". I'm not sure where it is or if this is what your problem is, but he says it's fairly common.

    Does Anybody Know Where The Back Pressure Valve Is Or Is There Another Adjustment On The Plow Like The Meyer Have

    You say it's leaking fluid do you have to refill the reservoir a lot? Does the plow cycle consently in the DP mode? If so you could have a lift ram leaking internally. The lift cylinder on a snoway w/DP is a double acting cylinder they will leak at the internal o-ring allowing the plow to drop particularly under driving impacts and when under power from the DP.

    ya that seems right i contacted snoway about it and they said pretty much the same but they also said that the plow dropping a little while driving in normal??? i dont think so..but this just started doing it i can raise it up a little just from sitting at a red light.. but anyway whats the best way to fix it without buying another lift cylender. other than this problem the plow it great and i will let you know what the prob was when i get it fixed

    There is a rebuild kit for the lift ram, but it's a pain in the a@#. We don't rebuild for customers, the parts and labor are so close to the cost of a new one it doesn't make (dollars and) sense. The problem with continuing to use the old one is eventually it's not going to stay up at all. If the internal O-ring bulges you're SOL. You'll be throwing the travel lock on and headed for the shop. It's a lot easier and less stressful to change the ram when the sun is shining
