I could be wrong, but i believe there are only 4 knock sensors on the M120. They only work with the ignition system, for misfire recognition it has a crank angle sensor.
It's mechanically a very durable engine.
Never seen any real serious problem in regards to the cooling system on either the 129 or 140 chassis.
