Looks like this winter was tough of all the seals on the 6 hyd cyl that are on my 3630 spray coupe. I noticed when I finished up last fall that one was leaking, but not bad. This spring they are now all leaking. I pulled them all off and will send them off to get rebuilt, I just hope they do a better job then Iv had in the past. Most of the time I get a cyl rebuilt it just never seams to last long and I uslly just wish I would of bought new ones.

your luck?
