Conrod Oil Hole Direction?

I wasn't paying enough attention, when I took the pistons off the conrods, as to which direction the conrod oil holes were facing.

Do the oil holes in the side of the conrod shafts:
1. all face to the centre of the block,
2. all face to the outside of the block,
3. all face to the left,
4. all face to the right.

 

i think the oil hole faces the outside of the block

 

do them exactly how the picture shows, all of them.

If you are looking at the piston and the front mark is at 12 o clock then the oil hole goes at 3 o clock.

They shoot oil to the thrust side i belive

 

Thanks. So the oil flow through them is by the rotational effect from the crankshaft?
