Where does one get that M8 1.0 pitch 12mm or so hex bolt with the hole in it. Or do you wizards make your own. I managed to snap mine. TIA

I took one from my mechanic's spare motor at the shop. He was out to lunch and I needed one quickly
True story, right Chris
Careful with that thing, torque spec is only 9N-m or something, very very low.
but yeah, 944online.com

Got mine from the dealer. I don't remember it costing that much. Maybe like $3. It just took the normal week to come in. In the meantime I went to a hardware store and got one without the hole and used that.

Michael,
Perfect timing! I've been trying to figure out what size that bolt is, I'm going to try putting a Speed Bleeder of the correct size in there instead. I'm hoping I'll be able hook some clear tubing up to the nipple, crack it open and then use the pressure bleeder w/o having coolant spew all over the front end of the motor.
I'll keep you posted on how it goes...thanks again for the sizing info

Thanks dudes. Speedbleeder. I have caused Exxon Valdesesque spills fiddling with that bleed bolt. Apparently some folks drill out the hole. The size again is 8mm 1.0 pitch 12mm long.

Does anyone know the purpose of the little hole drilled through the bleeder screw? It actually saved my butt. When I torqued the head off, there was a hole in the remaining piece of screw that I was able to twist out with a flathead. Is there some thermo dynamic principle behind the hole?

There is a hole down the length of the bolt and a hole (or two) drilled radially just under the head that intersect the one down the bolt length. The idea is to allow air to escape without having to unscrew the bolt very far.

I ordered an M8x1.0 Speedbleeder plus a hose & bag kit tonight, so we'll see how it goes. The site doesn't indictae how long the threaded part of the bleeder is, hopefully it'll work ok.
Keep your fingers crossed for me/us!
