oiling timing chain

Here is the bulletin Chrysler used when the chains were rattling on the early Dakotas. There was a recall due to the chains being loose from the cam to crank bore being to close. It was after this that everyone started using the bandaid tensioner. Do not use this on a roller chain. Also it is just more parts to worry about failing.

They make different length chain sets to correct chain slack. That is the proper way. If you are just doing a low budget street engine use what ever your heart desires.
