I finally got my 312 running after a year of working on it. I drilled and tapped the block in one of the bell crank mount holes to 1/4" pipe thread as recommended in a post here to install a pcv valve. I had questioned whether a baffle was needed and was told NO. The engine sucks so much oil thru this line that it fouls spark plugs in less than 5 minutes. Any ideas what I can do to correct this?   Dave V
