Super C Oil Flow

Finally getting back to my super c rebuild. I fired it up for the first time this morning. I?ve got an issue with the oil flow. Oil pressure reads good but no oil is getting to the top of the head and oil is leaking out the top of the oil filter canister. Any thoughts on what could cause this?

Well if the Super C is the same as an A or B engine in the lube system the oil for the head comes from the center bearing on the camshaft. Did the cam bearings get replaced? If so were the holes in cam bearing lined up with passages in the block.

Not real sure on the filter canister, any chance of posting a picture to get a better idea of exactly where?

There's no connection between your two issues, there needs to be a copper seal ring on the oil filter bolt (GASKET, oil filter case retaining bolt Product No: 13727D), and the oil to the rocker arms is metered through a cam bearing, improper cam bearing installation = no oil to the rocker arms, also (IIRC). (Were the cam bearings replaced?)

Also, the center rocker arm stud is special to allow for oil to pass from the head to the rocker arms.

Any chance the wrong one got installed or something in that area is clogged with debris?
 
That series engine has no cam bearing inserts, iron on iron. So the issue could be plugged up drilling to the top, or wrong
bolt in the rocker shaft mount/support. Jim

Well now don't I feel stupid! But in my defence it's been 30+ years since I had my BN engine apart and in the manual on oil flow it says:

"From the camshaft center bearing a driller passage leads up to the cylinder head, through the head to the valve lever shaft. The flow of oil is metered to the valve lever shaft by a slot in the camshaft journal which allows a small quantity of oil to flow each revolution of the cam shaft."

You have to go back six pages in the manual to find:
"The camshaft is mounted in the crankcase without bushings, the bore in the gray iron case forming the three bearing surfaces."
 
The center stud bolt that holds the valve rocker arm shaft is drilled to allow oil to pass through and supply the oil to the top. The hole may be plugged or the stud replaced with one that is not drilled preventing oil getting to the top. Stud is drilled from end and then into side to meet the center hole. I had to replace one of the studs several years ago. As I recall could not get from IH. I ended up drilling it myself.
