This sucks, I went to buy a used engine today for my 1993 850 Engine (s/n 133204} MFD date 5/93. Apparently the engines don't interchange for 1994 and newer - according to all the junkyards computer interchange systems, with no explanation. One did tell me he thought the intake man. was different but I think the s/n or build date is more important than the model year. I went to "THE VOLVO STORE" in "Winter Park" Florida for assistance in determining what engine is in this and pick up a rear main seal, and extra key, but was prompty rebuffed by the parts manager for wasting his time, "That's the way it is". What a a$$hole, I wanted to drag him over the counter and punch him out, but I left without the key and seal. I should have talked to a older mechanic I guess. I definately will never go there again and it's the only dealer in the Orlando area! What is different between 1993 and newer? I've found about 10 newer engines (cheap) and 1 1993 engine $$$.
Thanks
