I am planning putting in a timing chain/rails/tensioner in my 84 190E 2.3 automatic. I am a firm believer of going in once and replacing anything else in there that may be bad or go bad in the near future, rather than redo my labor twice. Or three times.

I may throw in a new water pump & gasket. What eles should be repaired once I'm in there??? I has around 170,000 miles on it.
