So......One of the maintenance issues with the 2014 and older LSA engines is the Isolator coupler between the drive pulley and the rotors.......originally it was designed with a spring mechanism to cushion the force put into the rotors.......well...in theory it worked perfectly........the downside is that the spring wears into the shaft and makes a Rattling noise that's sounds like marbles being ground up inside the unit........GM changed to a composite solid coupler that does the job and it's Quiet.....

So.........I decided to work on the Chevelle today and replace the coupler which requires the snout removal......Everything went smooth till it was time to break the snout loose.....Didn't want to come off, so....rather than force it , I decided to remove the whole assembly from the engine to do it correctly.........more work, but I can sleep at night now..............Got it all back together and all the marbles are gone.....LOL
