I just purchased a 1994 (late) 850 (non Turbo) with 184,000 miles and the rear seal leaks worse than a sieve (at least a sieve would slow it down). I plan on doing the fix myself. Is there any tricks/tips/hints that someone could give me that will save me time/skin/frustration in doing this job? Already checked the flame trap and that has been removed. I was told the rear pan bolts were checked and tightened (don't know about sealant) but the leak appears higher than the pan. I do plan on changing the timing belt and water pump while it is out, is there anything else I should change while I am in there?
