I have rebuilt a 22r I am getting oil to the oil filter, there seems to be a blockage after the oil filter, is there a diagram of how the oil flows through the block?

 

How do you know its blocked, I dont have diagrams but when my block was in the shop they took out 2 allen head bolts on the bottom of the block and forgot to replace them and i had no oil pressure.
Took the oilpan off and blocked off those two passages and its good as new.

 

Is it the same as the 22re?
