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

Pretty sure it will help someone in the future if they watch the vids.
I've got a cam so I can stick it down through the deck and see where the hole comes out but not much that can be done now.

The one guy offered the tip on making the crossover to start with small drill and work your way up in three steps.
This may apply when drilling the main to galley passages too.

Yes, I've learned a lot.
I now understand where all the oil goes and for what reason.
Pretty simple actually.

The set screw and expansion plug would have worked for the #1 main to galley repair.
Oil from main saddle could not go up to where the drill bit went out the side.
From the factory you have an expansion plug in the end of the galley keeping it separated from the water passage at the front of the block.

It's the #3 main that one can not get to or alienate from the rest of the system.

The biggest issue was starting the hole STRAIT and parallel to the existing hole.
On the ones I got lined up properly they drilled out easy and you could tell when it broke into the oil galley passage.
Was definite.
If at any time it starts drilling hard or your getting too many shavings coming out it's time to abort the project. LOL

From the quick flash of the video camera You did not need to do the set screw and plug on the number one Passage. You could have gone through that water jacket hole tap the hole and put a plug in it and still been able to use that block as originally intended.

The plugs at the end of The Galley at the front cover are not to separate water from the oil those are to keep oil from leaking out the end of the galley into the front cover area.

I would really like to see more of your video on the third main passage being drilled out it may not be as bad as you think.
Do me a favor and slow the movement of the camera so that I can get a better view of things.
Remember I'm very old.
