I am having the rear main seal and 2 bolts (flywheel?) replaced today on my '97 850 non-turbie after noticing an substantial oil leak coming from the "weep hole" at the transmission and oil pan. A local Volvo/BMW indie shop has qouted me a total price of $800. After inspecting the leak the service manager indicated that he would bet it is the bolts, as he has done this repair on many 850's. He did indicate that it could very well be the seal and would be replacing it as well since he would be in the same area. I am comfortable with having them do the repair as he seemed very knowledgeable of the information I shared with him from this web site, especially concerning the issue with the flame-trap. I asked him what was involved with the repair as I have read different opinions in getting to the seal. He indicated that they lower the subframe and pull the transmission, and the engine stays in tact. I asked him do they experience any complications when doing this repair related to things not being reassembled correctly or damaged during. He said that even though this is a very intrusive proceedure it is very straight forward and that everything would be fine. I guess my biggest fear is that other things will begin to crop up a result of this repair. Is there anything I should look for, other than the leak, or watch over the next couple of days? What about any damage to drive axles, boots, axle seals, sensors, etc? Aside from the leak the car runs flawlessly (knock-on-wood). I have only had to deal with some of the minor problems associated with the 850 such as top mount, t'stat, broken recirc. damper lever. However, I did notice a slight coolant smell inside the cabin after replacing the t'stat. I'm going to check the htr core connections when I get it back. So far I have good AC (knock-on-wood), but I am dreading the evaporator. Is there anyway to get at the inlet side of the evap to check for debris without removing the dash? Possibly vacuuming through the pollen filter access or it is just a crap-shoot?
