Broken nipple!
 

Hi, the nipple for the left side p/v cover vent pipe has sheared off flush. Does any one know the thread size for the nipple and also any ideas on getting it out? I would rather not take the top end apart, maybe an easy-out would do it although Im pretty good at breaking them in the hole!

Did it shear while trying to remove it or did it get sheared off some other way? If it was "some other way", it may come out with just a little friction from a phillips screwdriver.

It has been like it since I bought the bike so I dont know how it happend. I have'nt had a good look at it yet. Any idea on the thread size?

Should be M6 x 1. Since it already has a hole in it, and the inside(and threads) are oil soaked, careful use of an easy out should work fine.
