timing chain stretch

[cork]

Will slack in the timing chain cause a change in timing ?

The quick answer is.......No, it will not change your timing, you have a tensioner on stock engines that takes the stretch or slack out. A double roller timing chain does not stretch much at all, and does not require a tensioner.

Even the double roller stretch,but either way it will not effect ignition timing on the LC2 engine.
Timing is setup of the crank sensor.

The link chain will almost never stretch, and a double roller chain will not hardly wear either.

The slack comes as the gears wear. This slack affects cam timing, tensioner or not, but not ignition timing.
