Pete, Yeah, they were originally off my 95, but they looked in such good shape when i pulled it apart, i couldn't see any reason to replace them when building the 3L. Guess on this rebuild, I'm going to replace all of them, JIC.
As far as keeping tension, I noticed before i pulled my 2.5 apart, i did have a slight tick and found upon teardown it was coming from the front tensioner not pumping up due to a block oil passage from the pump. The tensioner was fine though.
Just had issue with providing tension.
