Working on a friends 220K mile '93 945T - has oil leaks all over the place, so I'm doing the 3 front seals (and timing belt), oil pan gasket & oil pickup tube orings, PCV box, breather drain tube (requires pan off the properly place the tube clear of the crank), distributor shaft seal & outer orings, dipstick tube oring, While its apart, doing the ancillary mount bushings, drive belts, AC repair, heater hose & valve relocation (improperly set in the past), and sundry odds & ends that come up on these.
Breather box was previously resealed - very badly
Ancillary bushings all look like these
Drive belts all look like this
Whomever did the last T/belt, dropped a cover bolt INSIDE the cover - amazing it didn't throw the belt
I keep a spare front cover, so I can install the two lower seals off the car, then press them the final 1/4" with the Volvo tools after the cover is on.
distributor leaking from the inside (after much cleaning)
had to make a tool to get the pin out
rebuilt with new shaft seal & orings
Also the distributor was missing the condensate trap to keep moisture out of the rotor & cap contact pins
Still much more to go. Subframe bolts were all seized - took quite some time to get them free without damage, Harmonic damper was rusted on to the crank snout, so I had to order a new one.
