Ok I have my heads off and removed my lifter trays and lifters. I don't notice until there were all out but my old lifters have a jet (maybe oil jet) on the bottom of all of them. My question is which way do the jets face, up towards top off the block or down, or does it matter?

Thank-you as always.

 

Makes no difference.

 

ok cool had no idea, what is the hole for?

Thank-you

 

its for oil
