HI All,
I could REALLY do with some advice on this, and i would be happy to take pics while im doing it but i need to know its the right move first,
I posted a couple of pics of the block on my Resto thread,

So as i see it, i drill the hole out from the inside face of the block (that mates to the sump) and then open the existing threaded hole up to a larger diameter for an oil return stub?


Thanks in advance
Rich
