Timing Chain

The tensioners were designed for 3.9 v6 engines that had chain rattle issues. From what I have seen, the stock timing set was steel gears and a standard chain. You don't need a tensioner with a good quality double roller. The nylon rubbing blocks on the tensioners are too narrow and not designed for a wide double roller chain.

I used to think that but virtu every engine I take apart the chain is junk. I just throw a tensioner on it and send it back out.

Ive seen SBC TC&G be shot in under a couple of thousand miles.
