I have a Smarty jr with the 5.12 version, does timing rattle hurt the motor? I hate to hear the injectors ratteling I'm on stock timing and thats the least ive heard the rattle just wondering about the longevity of more timing = more rattle. what would the long range results be?

 

More power and better efficiency. That's about it... seriously I've been running max timing for tens of thousands of miles now. All my oil analysis have come back very good. No worries.
