I have installed a remote oil filter on my 216. However the 1/8 pipe port toward the front of the block on driverside is supposed to be return port. With engine running I have pressure on it. Is that port connected to the spray nozzles for the connecting rods? And if it is, Does that mean the filter only filters at idle? I am using a restricted filter. The pressure port is teed in with the oil pressure gauge.
Are you using the canister style filter, S6 or similar?

That port on the forward part of the engine should be straight into the crankcase with no obstructions. It's the one circled in yellow in the second pic. The first is the diagram for the cannister filters offered as an accessory when out trucks were new.

Just so we understand, you removed the pipe plug and your getting pressure coming out of that port?
If that is the case, pressure in the crankcase is created from blow-by from the piston rings. The rings don’t seal perfectly so a little leaks by creating the pressure. The crankcase is vented by the road draft tube or PVC PCV system that was used on big trucks. Your road draft tube or PVC PCV system may be clogged with sludge. In addition, the oil fill cap should also be vented allowing fresh air to replace the crankcase blow-by being exhausted by the road draft tube. That could also be plugged.

The oil filter return line on a 216 or a spray oiler 325 plumbs into the rocker arm oiling system, downstream of the oil distributor valve. It's normal to have a small amount of pressure on that port. Pressure-oiled 235's have the filter return going back to the crankcase. Since the main oil gallery pressure is always higher than the rocker arm oil line, oil will still flow through the filter, either at idle or cruise speed. Jerry
