Do I need forced oiling to extend the life of my 06-08 bearing?
The fact of the matter is this engine is wet sump. The IMS is partially submerged in oil during normal operation and there is more than adequate oil mist and splash within the engine to lubricate the bearing. Utilizing a bearing without a grease seal is the optimal configuration, whether your choice is for a ball or roller bearing.
The M96 engine is well know for having excess crankcase windage and oil misting due to its propensity to suffer AOS (air oil separator) failures, which its primary purpose is to separate oil from the crankcase air and return it to the sump.
A ball bearing only needs a few cubic centimeters of oil per minute for proper lubrication and cooling. Full submersion or spray is completely unnecessary and will lead to further aeration of the oil.
The only IMS bearing that needs an oil feed is
the IMS Solution
as it is a plain bearing, like your engine's rod and main bearings.
The IMS Solution
backdates the M96 engine to a plain IMS bearing like on the aircooled Mezger engine.
