Air Injection Plug on 2L Head

ok, I've searched all over for the size of the plug on the 2L head for the air injection. I have found tons of information on the 1800 Head, but not for the 2000, does anyone know the size. Someone just told me (here I think) something about the threads but now I can't find that post again.

the threads in the head are 17mm by 1.5
The fitting that fits that hole has 1/2" pipe thread on the top, so you could easily cap it

Thanks Mark, If I cared for the cleaner look I could take the whole thing out, but I bet I have a 1/2 pipe cap laying around somewhere....

Dan, I found some oil drain plugs at the hardware that fit right in, and look good! I took my old valve to match it up.

Right, Dave. Get to Auto Zone or similar and ask to see their selection of metric oil pan plugs. take your old part with you for the exact match of threads.

Much cleaner looking.
