u cant use the holden sensor
pull the sensor off with 27mm deep socket
put it in vice
break off the black plastic part thats glued into the alloy part
centre of alloy part is a tiny hole
drill and tap to suit your
oil sensor
if the
oil sensor is too big diameter and hits the plastic inlet manifold then fit a 45 degree adapter
just make sure if the new
oil sensor is big and heavy that u use good quality 45 degree adapter and that u get good bite into the threads as u dont want sensor breaking of due to vibrations
