Just how accurate do you need the cam timing? Today's milling machines aren't accurate enough? I don't buy that as the reason for even a second. It was done because some young engineer thought he had a better idea and the bean counters bought it because it was going to get them more service work and/or require non- dealer shops to buy more unnecessary tooling. It's a STUPID system and was a solution without a problem. If you can build a tool set that holds the crank and cams in "perfect" position, you can cut a keyway just as accurately.Removing the keyways wasn't done to reduce manufacturing cost, it was done to enable more exact cam timing-pin everything in place and torque it up- AS LONG AS IT HOLDS, the timing is spot on, not within tolerances. Cars are more complicated than ever but they last longer than ever before.
