Do you have a better pic?

 

it goes in the deck of your block they take them out when they deck them. It goes in the middle top intake side. there should be a hole that goes right down to the where the oil filter goes

 

It's the oil control orifice. Fits in the block between the head. You NEED it there.

 

got it, thanks guys... Funny that in the tech book for Honda it specifies not to replace it..? But by that point i'd already bolted the head on.
