Where the original BJ7 tensioner bolts to the block there is a dowel pin
looking part (fitted into the block) that has a small oil hole. The
original tensioner part has an open bore that corresponds with the pin.
Pretty obvious that the oil comes through the small hole and provides
pressure to tension the chain.
Problem is, the new tensioner does not have the open bore. Instead it
only has a small hole and it does not line up exactly with the small
hole on the dowel pin.
Do I need to modify the new tensioner by milling a step bore or open
bore? Or is the solution to pull the 'dowel pin' in the block?
