Hi everyone,
I have just purchased a 1996 850R wagon, black on black, with 152K miles. I understand that the timing belt has not been replaced (at 140K), so the first thing I will do is have that done. I have checked with five dealers and a few indy shops as to what else should be done at this time. Prices and opinions vary. I have searched this site and see that there have been a few threads on the subject as well and numerous different theories. So this may seem redundant, but I would like to know if anyone has experience with turbo and especially R engines with 150K+ miles, and can recommend which parts to replace. Most people recommend the T-belt tensioner at this time. What about the tensioner and idler pulleys and water pump? I know that with careful inspection and physical exam one can usually tell if a system is healthy or not. The Haynes manual indicates that the T-belt tensioner and pulleys can be inspected and should be replaced if they show signs of wear or malfunction. I have also read about water pumps being replaced "while you are in there" only to fail prematurely or leak at the seal. I do believe in "leaving well enough alone" and would just assume not triple the price of this service unless there is strong evidence it should be done.
Thanks very much,
Jeff
