Oil Pressure - Schematic of oil route on a 302 block

[spirockp]

Does anyone know of any good web sites for info on oil routes on a 302 block. I'm looking from oil pick up to where it goes before re-entering the pan.

The reason I ask is because I'm trying to solve a oil pressure issue.

Thanks.

Ok let me ask another question. When does the oil pressure sending unit measure it's pressure? Rights after the oil comes out of the filer, or after it gets passed through the rest of the motor?

The pressure switch either reads the pressure before or just after the filter. It would read the pressure prior to the point that the oil is in a position to lube a bearing. I'm pretty sure the crank gets oil first, camshaft is second, then the lifters. The oil in the lifters passes thru the push-rods to lube the rockers and valves. Oversimplified, but thats pretty much it.

Just the answer I was looking for.

Thanks.
