I hadn"t run my 1980 555 this winter, except to start it a couple times to check the hydraulic pressure after installing a filter (ran it for less than 5 minutes). After the last time I did this, I noticed a large puddle of fluid under the PS reservoir.I got a chance to look at it closely this weekend, and the PS reservoir was empty. (It was full in the fall.) I filled the reservoir (134 hyd. fluid) and started it up, and after a minute or two, the steering was back, and there didn"t appear to be any leaks. However, the fluid is now frothy, indicating I"ve somehow gotten water in the power steering. I also noticed that the tank was slightly pressurized when I checked the level (with the engine off, but only ran the engine for less than 2 minutes, so it was hardly warm). The coolant doesn"t appear to be oily. My neighbor said that the tank could pressurize if the fluid level is too high or too low, but this doesn"t explain the water. If there"s a PS cooler, maybe I have a leaky seal? Any suggestions? Thanks. JB
