</div><div>That was one of the first ideas I came up with but the new hole would have to be drilled thru the crankcase, probably straight through the little brass button situated just below the pressure nipple and then it would need to be 'stopped' or resealed off once the correct airway had been re-established in order that the crankcase pressure is maintained and routed correctly.<div>
</div><div>I've removed the brass sleeve from the crankcase quite easily, apart from 'burring' one edge slightly. I'm thinking that the biggest difficulty will be in getting it correctly aligned with the existing hole, driving the sleeve back in squarely, and doing it very quickly and in 'one go' as XMANS suggests.</div><div>
</div><div>I'm thinking of a wood dowel fitted tightly into the brass sleeve with a 'shoulder or step' the same diameter as the brass sleeve. If the dowel is 6 - 8'' or so in length I should have enough control to make handling and placement manageable. I take Xmans point about getting it right first time as the temps will be quickly acting against each other.  I also think that I will enlarge the existing brass sleeve hole x 1 which will make the placement slightly less critical. </div></div><div>
</div><div>If anyone see's a big hole this plan please............sally forth!</div><div>
