My take on the oiling system crossover tube for the small block

Yikes!!
I just drilled the opposite side Oil galley feed passage right into the water jacket.
Some how my angle was off and the bit did not follow the current hole.
Drill bit snapped when I was an inch from the galley target, it shot out the other side of the block.....I'm like, Uhhhh,
that's not good.

I tapped and PLUGGED that feed going up to the left side galley just as if I was going to use solid roller lifters.
Used JB weld and Red Loctite on the set screw. Don't want water leaking into my oil.
Now from looking at the oiling diagram it appears I MUST install the crossover to feed oil to my hydraulic lifters on that side.

How will this effect oiling to #4 which is suppose to be the only reason for the crossover in the first place?????
Phooey!
