oilin system question

[dohcfiend]

i never thought about this but how does a typical system work? i know the pump takes in oil through the pickup but after that i am clueless.

how does it get back in the pan? and where in the whole process does the oil filter come into play?

GEN3-pump, filter, mains/conrods/cam, lifters/valvetrain

TDC-pump, filter, mains/conrods/intermediate shaft, cams/lifters

GEN2-1-pump, filter, lifters/valvetrain, mains/conrods/cam

It gets back to the pan via gravity. After it seaps out the bearing clearances and the ends of the pushrods.

If you take out a service manual at the library it will have a diagram. Or goto www.howstuffworks.com.

Oh the pump is a simple gear type pump.

That's not exactly accurate:

GEN3-pump, filter, mains/conrods
............................lifters/cam/valvetrain

On the gen3 the mains and cam gets oiled at the same time, due to the revised oiling pattern, similar to a SBC 3 galley system.

TDC.

gen1/2 pump, filter, lifters/valvetrain
.............................cam/mains.conrods

You had the lower oiling system backwards, the left oil galley (cyl 2,4,6) gets oil first, directly from the oil filter, through a galley that is bored from the lifter valley, genIII is similar, as far as how the oil gets from the fiter the oil galleys.

appreciate it. basically it goes to the pump, to the filter, up to the top and drips down.

Obvioulsy I was simplifying it. I'm well aware of how the oiling system works.
