We have removed the outer seal on many M97 IMS bearings, on automobiles with mileage well below 30k miles and all have had substantial engine oil contamination.
Yes, I do recommend switching to a boutique type of engine oil, instead of Mobil-1, because I feel that elevated levels of ZDDP is critical to most any engines health.

Tony,
What do you use to pull the seal off the bearing? I have replaced an IMS bearing on the M96 and understand securing the crank, cams, chains, and shaft, but what do you use to reach-in and grab the outer seal on the M97 bearing?
Thanks Much
