If not much, and I dont see any shavings got into the SC then I'll just replace the isolator myself and call it a day. If there is substantial damage and it looks like the metal shaving might have gotten into the SC housing itself I'll go the dealer route..

I'm just hoping not to have to remove the ATI damper and 18% OD pulley and some other parts for the dealer option.... lol

They did improve the spring as the designer argued that the spring has an advantage with lag opposed to no lag on a pin over a lifetime. Remember they were thinking 10 years or 120K miles. Yep I agree if removing the ATI you might as well rebuild it..
