    Diferences of the block between 3B/ABY/ADU/AAN

    Hi!

    The block of my ABY is broken. I'm searching a compatible block.

    What are the diference between the block of an ABY, a 3B an ADU and a AAN?

    Sorry for my english!

    Regards!

      Is there some difference with AC and non AC cars?

      7A engines done have the port for the turbo oil return.

            yep, you got me on that one, the 7a and 3b from s2 and aby/adu lacks also the turbo oil return hole, the place for it is there but it is "blind". AAN and 3B from 20020v has got hole.
