truckernix is correct about the "full-pressure" lubrication of cam and main bearings, the rocker arm assembly, and the timing gears). The "dipper" system for rod bearing lubrication is not really a "splash-oil" system (as many people now call it) - see below.
Quiz:
Does the "dipper" system actually collect oil as the dippers move through the oil near the bottom of the pan?
Or, do the dippers receive oil that is sprayed into them by an array of tubes that are fed by the oil pump?
Or, does the "dipper" system rely on a combination of the above?
The answer is :
All of The Above (see the lubrication section in this Shop Manual).
