pete 23 said: (quoted from post at 13:54:56 05/02/14) You are confusing me here. The oil supply to the head is through the external line going into front of head. No passages up through block to the head. Early model 361 were different from later model and all 407 engines. I don't have my book here to check right now. I think I am thinking right that the early model 361 fed off the oil cooler manifold and used an orfice in the elbow at the head to meter the flow and later models and all 407's used the cam bearing to meter the flow however they still used the pipe to head. So, if that is the case, your cam bearing is still plugging the hole needed for lube. You could then run off the clean side of filter base and use the orfice fitting instead of tearing engine back apart. I will look in service manual later and check this out a little farther.
Just run it a little and see if any oil is coming through to that elbow in head.
I couldn't remember either so I got out the book to look it up.
Early engines fed from the oil cooler rear header were the ones that had the oil metered by the camshaft. They use the standard fitting with no orifice. Later engines that were fed from a block oil galley need the orifice type fitting.
