Little round Plug/bush style thing on engine block

[ANDREW001]

Does anyone have one of the little metal bushes that sit in the engine/cylinder head so both can mate to each other. I believe there are supposed to be two of these my engine only has one

There only dowels that allow you to align the head on the block and keep it aligned during the torquing of the head.

Probaly best to get another one, nissan would be your best bet.

yes there should be 2 and you need them both in place
