Guest Posted October 9, 2018 Report Share Posted October 9, 2018 4 hours ago, Cyril Gibb said: My understanding... The area of concern in our engines for starting are the cam lobes and lifters. The cam is "splash lubricated" by the crankshaft thrashing around. Unlike an automotive engine, the cam is not drilled to allow oil to be spread onto the contact surfaces from the pressurised oil gallery. Unless you have the cam drilled (STC) or ney nozzles installed (by STC), pre-oiling does nothing. I've wondered why the engine manufacturers don't just drill a hole on the backside of each lobe like the centrilube stc does.... That would be admitting that their design has flaws and likely open them to numerous lawsuits. An STC is someone else’s improvement, with no fault to the manufacturer.
