| 2 of the oil pressure, also drop in pressure when braking. The amount of oil held in the passages of the engine is absorbing the heat, hence our high temperatures. We have proved the amount in the passages by carefully checking up the oil in the base chamber standing, and at different speeds. We fitted a pipe for the release oil taking it direct to the filler. This gave us the same amount of drag or slowness of the oil returning to the base. To overcome this feature a direct feed back from the release is required and the oil supply for the camshaft, ignition etc. should be from a bye pass This could be done by keeping the first oil pressure unit, and using the extra oil for the cylinder to feed the | ||
