L16 Manifold Frost plug

[classicdat]

Anyone know what frost plug is needed for my inlet manifold, directly up under the Carb, mine is dripping water onto the manifold?
Got home today and my Daughter asked what the funny sizzling noise was, checking closer I found water dripping out onto the manifold, hence no tell tale drips on the drive, lucky save I reckon.

Can anyone tell me the size plug I need or even have one laying around?

Should be able to rip it out and just measure it up. They are readily from available from repco/bnt etc.

Or measure it before you take it out

Thanx Guys, was keen to do it all at once, just lazy really.
I'll just have to add it to my list of things to do before the weekend.
