Hey Steve mate,no worries about correcting me on the torx bolts,heck I haven't been out in the workshop for such a long time,I'm going to have to learn what is a flat slot,phillips, pozi screwdrivers from a 6" adjustable left hand spanner. The screw in the oil pump is a torx scew eh??? And man, you will have to change the oil after everytime you run that engine so that you know every thing is spotless.
