StickyHydro,
WFO=Wide F'in Open?
Uh, at your own risk.
Before you start beating on the thing, I'd recommend doing a bit of oil analysis to see if you have anything internal that's not doing too well...
Check with a company like Blackstone Labs. Oil analysis will clue you in to things like bearings going south, potential head gasket catastrophies etc.
