Mark,

   18mm oil pan plugs (at any auto store) are readly available but if I remember

correctly they are 1.5 thread pitch (You might check this)............

Kelly, 

 

Short story is that this is the tap size I had handy that fit the hole.  We're trying to plug the heater port on the rear housing.  Who would have thought that an 18mm x 2.0 would be an oddball size!  We found a place that sells 18mm x 2.0 nuts, but they tell us that nobody makes an 18 x 2.0 bolt.  That seems hard to believe.

You will have a hard time for that. M18 x 2.5 is standard and first choice fine is 18 x 1.5 . You may have to get it made.
