Well on my 1951 216, this is not the case. The fitting where the filter outlet attached to actually leads to the low pressure side of the oil distributor valve. | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | In that case, the only time much filtering is going on is at idle, or other times when the oil distributor is at least partially closed. Once the pressures are close to equal on both sides of the distribution valve, little if any flow will get through the filter. I wonder if that's another way to assure the rods and mains get enough oil flow to stay lubed? Full pressure engines do drain the filter back to the oil pan through a port to the pan rail and a notch in the pan gasket.
