I am in the process of cleaning and reassembling the engine right now.  I will know more next week when I crank it over and check for oil pressure.  So far, I have not found an answer as to why there is no oil pressure to the head. I did open up the top hole in the front cam bearing.  It was 1/3 the size of the old bearing.

I don't believe the groove in the camshaft has anything to do with oil making it up to the top of the block. I would suspect an issue at the front main bearing shell, perhaps a clogged oil passage, if you are sure oil is making it's way to the main bearings.

Yes, I'm getting oil pressure 80psi on the started motor.  I have oil flowing too when I pulled the pipe off of the front ot the block whilst cranking.  Not oil came out of the top of the cylinder head or the top of the block.  I;m startign to think that the holes in the cam bearing are to small and do not overlap the cams grooves sufficiently.

I"m curious how you know you do not get any oil to the top of the block. Are you getting ANY oil pressure reading at all?


The oil gets to the camshaft via the main bearing. If you have a spun main bearing, it could prevent oil from getting from your main to your cam to your head.

First confirm you have oil in your oil galleys while cranking by pulling out your oil pressure sending unit or your oil gauge capilary fitting and see if any oil comes out while you are cranking.

Have you got the hollow rocker pedestal lining up with feed hole in the head and rocker shaft?

I have a 1965 Mini Cooper with a 1275 A+.  I have no oil pressure to the head on the rebuilt engine.  There is no oil pressure to the top of the block with the head removed.  I have the engine out and disassembled now.  There are no obstructions in the oil hole to the front main.  The cam bearings are new and pressed in correctly.  Both align with their respective holes.  What is different is that the small hole to the upper part of the block is much smaller than the old bearing hole.  Also, the small hole in the bearing does not overlap with the groove on the cam.  There are two small grooves 1/2" or so that are perpendicular to the circumference groove.  Is this enough to supply oil to the head?  I have a turbo oil pump installed which should put out even more oil, yet it does not supply any to the cylinder head.  Puzzled!
