When you truck is dead cold and you go to take off and you hear a little tingy sound. That is a little timing rattle. these new trucks are so quiet you can definitely here it.

If you have that sound or a little more then that is what you are hearing. You should have some with the module you are running.

 

So timeing rattle is bad? It is harmful to the engin?
