1995 Volvo SX 5.0L outdrive trim is leaking down over night

[Browndog801]

The trim works fine but when I leave it up over night it is slowly coming down. Is this an O ring in the pump. Will I be able to get parts?

Yeah, you can get parts.

Here is a link to the service manual for your drive (just in case you don't have one.) It has a complete section on troubleshooting and servicing your trim system.
