No oil from passenger side rockers?

jrstock · 04-03-2016, 07:26 PM

Recently rebuilt SBC. When priming the engine the drivers side rocker arms do get oil and the engine builds oil pressure. However all 8 passenger rockers are not oiling. There are no oil restrictors in the block.

The camshaft oil plugs at the back of the block have been backed off to ensure they are not restricting flow. When the rear passenger oil plug is completely removed plenty of oil does flow when the motor is primed.

Does anyone have any ideas or experiences with this?

Could the oil groove in the priming tool be misaligned? The oil priming tool is the type that simulates the distributor and has a oil groove at the bottom of the tool. Could the the oil priming tool not be properly aligned and thus the oil groove is too deep or high in the block?

Thanks for your help in advance.
