Some of the information we have gathered is related to shockloading the IMS sees as the transmission of loads from the variocam is sent upstream to the IMS through the timing chains.

The IMS bearings do not have very much longitudinal thrust capability and these shock loads place a lot of shock on these bearing, a portion of that is thrust.

Don't quote me on any of this, as lots of questions are still unanswered and I am working hard to prove whats occurring as the engine is running with the variocam engaging/disengaging continually.

Thats all I am willing to state now and I reserve the right to change this based on future findings.
