If you tap carefully then the majority of the swarf should come out as you tap the hole, but after complete, I suggest flushing the gearbox with petrol, which can be done by pumping it in through the sump plug and watching for what drains out... You'll be surprised what will come out... also as the casing is aluminium, then at least its not as abrasive as steel and will get fairly well ground by the gears anyway...

flappy-what vehicle did teh larger plug you used come from?i couldnt believe it when mine stripped! i looked inside at teh thread, and noticed that 3 bits were missing, so i probed tiwh a knife to make sure no other bits were about to fall off, and the whole thread came out in 3 bits! BUGGER!
a well!
thanks guys, ill ask for a price to get it helicoiled, but giving teh current financial status (after a £250 round trip to spamspeed yesterday) i guess itll be retapped to teh next size.... whatever that may be?

I'd avoid taper plugs in an aluminum sump. Taper plugs act like a wedge and will work to split the tapped hole apart slowly. The other problem with putting a tapered plug in there is that I doubt you'll find one with a magnet. All the Mini drain plugs I've worked with have benefited from a magnet to catch engine debris before the oil pump does.
94 GBP sounds like an AWFUL lot for this job. Mini Mania (the U.S. equivalent to Mini Spares) sells the HeliCoil kit for the sump for about $50 (25 GBP) which is a great deal. One problem with installing the kit with the engine in the car is keeping everything "square". It's easy to tap at a slight angle which makes sealing the drain difficult. If you're at all in doubt, don't use the stock copper sealing washer. I believe you'll find that 14mm nylon drain plug washers will fit the drain plug well and these will "crush" to fill any gap created by a tapped hole that isn't perpendicular. I run a drain plug seal from MotorMite. This is a metal ring with an o-ring bonded to it's center. The drain plug pulls up tight against the metal ring limiting the amount of crush you put on the o-ring.
