That isn't mush of a leak, but it makes a mess all the same.Thanks Tazza. I'll get hunting as soon as I can. It is only leaking about a teaspoon a month. Actually I'm already running on the cheap oil after draining the oil that had water in it. My plan was to go 20 hours and then change the oil along with the filters. Now I guess I'll be changing the charge pressure switch also. I'm at about 10 hours since the rebuild. I also have a tee at the charge pressure switch with a 6 foot hose running to the cab. So I already have both a gauge and the warning light. I'm glad I had both going or I would be freaking out again thinking that I'd be tearing the hydrostat back out again.
Hopefully it's just a leaky fitting, but the fun part is finding where it is......
