Cam Bearing issue?

We've been having oiling issues to the heads (old style bae) which burned the pushrod cups etc... and upon inspection noticed that the #4 cam bearing did not expose the oil gallies in the block to feed the heads. I also noticed that there was no button on the bearing to keep it from turning (which is what i thought happened) so when i had the block repaired last year i requested they install the button to prevent it.

I just went out to clean the block (JP1) to begin assembly and noticed that the button is installed but the oil holes are still covered up. I took some brake cleaner and from the deck oil passage shot some down each and it comes out between the block and the back of the cam bearing and on one side where there is just a little of the hole showing out the hole opening and between the block and bearing.

This isn't right is it?? and are there different cam bearing hole angles for different blocks??? or are these drilled by the user? confused...

 

You need to drill the cam bearing. Take a long 3/16 drill bit and drill the cam bearing. Then you need to make oil grove on the cam wider and deeper

 

thanks, KJC

 

KJC is correct, been there done that, I then made an oil pump priming tool that I spin counter-clockwise with a large electric drill at slow rpm (otherwise it burns your drill out).

I then found way too much oil to the top of the motor so in went .100" oil restrictors in each head, problem solved.
