Gasket For "Cooling Nozzle" On Top Of Engine

[Brozoar]

Hey folks,

I pressure-tested my cooling system earlier in preparation for purging the air, and discovered a slow leak that looks like it's coming from the base of the little metal "coolant nozzle" atop the cylinder head. For reference, it's the bolted-on metal nozzle that holds the 12mm bleeder screw that Clark's Garage tells you to loosen in order to purge the air (at the front of the engine, on top).

Does this have a proper name? Anyone know where to find the gasket that seals it to the head?

Anddd 5 seconds later I find it. How I wish I could delete my own thread.

If ever you can't find it, it's the "Water Hose Flange on Cylinder Head."

I'm going to piggyback an actual question here now so I don't have to start a new thread.

I've got a leak at the drain plug, as well. It's a 951, so it should (as far as I know) have a black plastic drain plug rather than a blue one. Alas; it has the blue one.

Is anyone on here an authority on those drain plugs? Because I'm wondering what this says about my rad. I gather that the only real difference with the plugs is thread pitch... but I'm open to insight from someone who knows better.

This one has the 1.5mm pitch.

Here is the 1.0mm thread pitch:
