Breather Valve had been leaking some oil for a while. Finally got around to pulling it off, cleaned it up nice inside and out, replaced the hose clamp and I think that fixed it. I think it had just gotten all gummed up and/or clogged at some point. Oil change, pulled the wiper motor assembly apart because the sprayer hasn't been working right for a while. I think it wasn't getting suction, air leak. Cleaned it up pretty well and tightened it back up. It started pumping, but the white plastic gear inside was sticking, also leading to the intermittent problem, so I pulled that off and the grease that was originally in there was more like glue. Cleaned that all off and re-greased it. I can see where I'm going now! Next up: dedicated tranny cooler (I tow really heavy trailers often), 4" ORD lift kit, 27" HMMWV tires and beadlocks. Also need to repack front bearings and replace diff and transfer case seals. Yippy!
