June 2014 Excellence tech section contains a big piece on IMS bearings, prompted by the failure of one in a 2005 997 with 47k miles, as well as a 2007 997 owner inquiring about his (larger, virtually non-replaceable) IMS bearing.
What is frustrating is they still regard an IMS bearing retrofit, along with removing the outer bearing seal on the 2006+ models as the appropriate preventative measures. They're also pushing spin-on oil filters and magnetic drain plugs.
I'm not suggesting that they are necessarily wrong, but the omission of any reference to Pedro's DOF is frustrating. I'm baffled as to why they make no mention of it.
Pedro, have you sent the Excellence editors a sample of your DOF?
