Detroits should have air from the blower box drains at the engine when running. If not, they are plugged. Unplug them. There will always be oil from them as the piston wipes the cylinder wall. Some of that oil winds up in the blower box.
Since the radiator is aft of the engine, the blower box drains should be routed aft of the radiator. That keeps the oil out of the radiator fins which causes them to collect dirt and then stopping air flow through the core.
If you can rig up the canister, that works also. Just keep the oil out of the radiator. If you’re experiencing HWT, thoroughly clean the fins and core. You should be able to see through the core with a light.
My two cents worth.
