They even had to lock the cams down and pull the tensioners so they could remove the IMS flange. It's only another half hour to remove and install the IMS bearing. In my case, once I got the flange off the IMS bearing swap was real easy other than having to puzzle out how to get that spriro-loc ring thing in place. A professional mechanic should already know how to do that.

You can tell they pulled one tensioner because they billed for part 900 123 147 30, which is the sealing ring for a chain tensioner.

I wonder whether they pulled the rear rubber seal on the IMS bearing, which is the hillbilly fix for an OEM dual-row IMS bearing.
