I think that the oil pressure-fed tensioners were introduced in 1984, along with the 3.2 carrera. Cars built before that, like my '79, had mechanical tensioners from the factory. Mine still had the factory tensioners when I purchased it back in 2007.

I'm pretty sure I've read somewhere that its possible to modify the oil-fed tensioners and install safety collars. It seems that either type of tensioner can fail. I do believe that the 930 mechanical tensioners are different than the NA cars and are considered superior if you choose to run mechanicals.
