There's been several threads lately on heads vents, so here's another one. I'm finishing up getting a 2.0L motor ready to install and venting the heads were on my to do list. Went to a local industrial tools place today and picked up two 3/8 npt nipples that I use with my shop air hose quick disconnects, a tap, and a new 7/16" drill bit. Total cost $13.00.
