You got it right there.
Was discussing that with Tim yesterday and Ryan Bean at BDP earlier today. If you look up the flow demand for the bearings in this engine and caculate it out, the passenger side bank could have as much as 8 psi of negative pressure differential at full pump capacity...this would reduce the piston jet flow SIGNIFICANTLY and decrease the cooling capacity of that bank far more than enough to cause damage.
Thanks for the ideas everyone, will be working on a fix ASAP.
