This one is pretty new, and I couldn't find any posts about it. Apparently there were some soft engine isolators that shipped with some of the firewall forward kits. The order ship dates for these soft isolators was from August 5, 2009, to June 30, 2016. Wow! That's wide range. Anyway, according to the notification you need to look for raised text somewhere around the exposed perimeter of the isolator. Since it was oil change time, and I had the cowl off, it was a perfect time to do the inspection. Sadly, all four of my isolators are missing the raised text. So, I followed the instructions which was to contact Van's. They are sending out the correct isolators. According to the notification, it is a 6 hr job to replace them, and you are to use section 46 of the builders manual as a guide. I'm not sure what needs to come off to do this, but it looks pretty intimidating to me, almost like a complete engine R & R. There is no specific outline for changing them, other than the builders manual, but I am hopeful that I will find some shot cuts as I go through the process. Anyone else hit with this one? The good part is that Van's folks watches out for us, and are prompt to notify us and make it right.
