[QUOTE="billrbg, post: 78030, member: 10970"] BIG bummer!!! I fired it up this morning, found a large leak in the side of the hose from vane-pump to Control Valve. I think I can change that hose without disturbing anything else (except oil level, of course); I'm going to try doing it "wet" without prior draining of any fluid. That is a weird hose, -8 fitting on one end, -12 on the other. It will be Tuesday before I can get another hose. And, "no", I don't think that was the original leaking problem. That hose has been dry until I started it up this morning. I had to bend that thing around to get it out of my way while working on the Control Valve, that might have "pushed it over the edge". At least all the linkage over there is well-lubed now... I sure wish there had been an easy way to spin the pump spline and pressurize the system while the engine was out! [/QUOTE]
