I have a 2004 vintage Legacy and the heat soak issue is common with my pump (I use the dump valve).   Recently, sitting on the ramp with no engine running, I now can hear short pump cycles every few minutes.  There are no obvious leaks but a few drops of hydraulic fluid are on the nose actuator so I suppose this could cause a pump actuation if there is a small leak.  I suppose it could be the dump valve also.

My question is what process would you suggest for targeting this thing before it gets worse.  Whatever testing stuff I need I can get locally here at the airport.  I see the oildyne schematics in the archives and all the comments on spool valves, fixes and electronic upgrades so I have all that as a reference.  Thanks.
