that's one opinion. I have another. Driving a non BS motor is like living in a threshing machine with the farmer caught inside the blades. It buzzez like a cicada. I had the ps pump bracket bread from vibration fatigue 3 times, and the pot metal a/c comp bracket went into about 10 pieces. I had read errors on the cd player. The balance shafts spin at twice engine speed, but the bearings live just fine with plenty of oil and pressure.

Ditto Kevin on the chain...
