I have read different views on this, my JJ1400 is at 9 oclock viewed from behind and my Wren Mk2 is at 6 o'clock from the glow plug.

BJ you dont want the egt probe to be able to move, it should be secured to the turbine or the turbine mount and bent in such a way that it is being sprung into the hole so it wont come out or move.
