I have had a problem with my spltter leaking fluid through the upper cap on the valve. I've read through the forums and it seemed the problem was the o-rings. I have replaced the two O-rings twice with the type mentioned on some of the other treads and it continues to leak after 1-3 hours of splitting. I'm thinking now its more than just the O ring. after a few hours when its leaking the ram comes down very slowly even stops. It retracts fine. I am now looking to just buy the complete assembly. Troy built OEM parts number for the valve is 718-0481 which is now replaced by part number 918-0481A, I have found this valve for $178.86 which I thought was a little pricey. The cap on the valve says "Energy" so I went to their website and saw valve Model C-908 DSKCVA 200 which is a 4 way valve for $85. I'm not sure if this valve will work on my splitter. Does anyone have any info on which valve to get? Thanks!
