Hot Rods Oiling Banger OHV Head

I have a Model B engine, drilled for pressure with 60 PSI Cold, and 40-60 PSI Warm-hot, depending on RPM.

I have a 1/8 line from the block to the head for oiling, but I am concerned that if the flow is not restricted, it will pump more oil to the head than the passages can return to the pan.

My thought is to use an In-Line Adjustable Valve ( don't know where to get one) and adjust the valve with the engine is running to ensure all the rockers ge oil with the engine running, but not too much oil to the head.

Approach should good? Any suggestions of the type of valve and where to get one?

Thanks for any help.

Any chance a poppet valve like used in a mechanical fuel injection system would work should be some that are adjustable or set for a certain pressure.

 

Why not just solder shut a fitting in the line somewhere, and then drill a .060 or so orifice to restrict the flow? You can keep increasing the orifice diameter until you get the amount of oil that you're comfortable with. My Buick Straight 8's oil the top through a metered orifice, should work on an OHV Banger as well.

 

Do you know it will pump more oil than the return holes can handle?????

 

No for sure, based on the volume, pressure, and the return through the valve guides, I was looking for the best way to regulate the amount of oil going to the head/rockers. I was going to check it with the valve cover off.

 

1/8 NPT needle tap adjust as required

 

If you want to be cagy put a fitting in the line that you can screw a carb jet into. This will allow you almost infinite control of oil flow, and easy adjustment by changing jets.

If you want to be real cagy, use an oversize carb jet and stick a cotter pin through it. This will prevent the little hole from getting plugged by dirt and sludge. Not that you will allow any dirt or sludge in your engine lol.

This is how Vincent handled the problem of top end oiling on the Black Shadow.
