I have the 2003 non-turbo version plus the service
& parts manuals
for turbo & non-turbo versions.I have also had mine stripped apart,except for pistons & crank.
Volvo Penta Schematic Part Diagrams
Here is a link to parts manuals
From ur pic,I can see salt
on the bottom edge of the "Regulator" cover(Volvo speak for Governor assy)
There is no RW or FW in the governor to leak out.
I suspect ur RW leak is the RW pump seals
& the RW is being blown back along the port side of eng.
If you remove the pump(3 bolts & it pulls right out),u will see drain hole between pump body & drive gear
end.If u see salt
there,u have found leak.
P/N for turbo RW repair kit shows 876060-& includes new shaft,all seals & bearings-just about everything except housing.Check that ur pump shaft is splined,where impeller goes on.My 2003 non-turbo is same pump,except shaft has a "screwdriver" slot for impeller.
I have rebuilt one by just buying
the seals-the shaft & bearings,etc.were in perfect condition.
These engines are "hated" mostly because of the rubber ring seals used on the push-in plumbing
connections.I learned the hard way to buy new rubber rings(plus spares),lightly sand the pipe ends & the sockets(a plumbers copper pipe cleaning
tool is great) & use petroleum jelly(Vaseline) for assy.Also,make sure the pipe (with seal on it) is inserted ALL the way to bottom,& STAYS that way until mechanically fastened in place.Some juggling is involved!I also found there is a sequence to follow,especially from t-stat thru heat x-chngr,when assembling these pipes.Very difficult removing & re-installing a pipe "in the middle",without loosening & jiggling components such as exhaust
ell,H Xchngr,T-stat hsg,etc,in order to get pipes fully bottomed in their sockets.Many sermons....
Hope this helps / Len
