    Anyone know where this throttle body hose should go?

    Hi all, i cant seem to locate where on the engine block hose number 19 in the pic below goes to. Can anyone tell me where to look on the block to find it please? Any help appreciated. Thanks

    It runs to a port on the top, rear, driver-side corner of the block, just below the head, IIRC.

      Oops, just saw you're in Ireland, opposite driver-side! Top, rear, left corner of the block. Same side as the throttle body is on.

        Thanks for that. I found it straight away as soon as i read your comment. Just couldnt place it as the engine has been apart for some time now. Thanks!

          I have already made these connections but after better understanding what happens inside the throttlebody heater I suppose it does not matter which hose goes to the top or bottom, does it?
