Upon disassembling the xover valve, i received a face full of oil. Cleaned it and reassembled, same damn thing. Upon trying to angle right, the plow goes left and stays. Try to uncouple the hose, I find the hose for the right side cylinder has o much pressure that I cannot uncouple it w/o bleeding the pressure one ay or another. I am at my wit's end with this thing. Any freakin' ideas? The next thing I guess would be to replace the xover valve maybe?
