[Fot] Extended bottoming tap for TR4 engine

[Greg And Alison Blake]

I just use a normal length bottoming tap and use a 1/4 socket extension to
reach the bottom. You'll want to find the right size socket to marry up with
the tap and then use some tape or something in case the socket wants to
separate from the tap upon removal.
