http://www.ukstarletowners.com/topic/56247-diy-twin-breather-cam-cover/ I'm going to be using this guide to make my own duel breather rocker cover but my only issue is I have an n/a rocker cover on my glanza :s Is this still possible? Do I just drill out the holes that the guide has drilled out even though I don't have the one to left next to cam cover? Another issue I have if I drill out the far left side next to cam cover I will have 3 holes in total :s PCV, far right and far left. How would you recommend I get round this? Thanks in advance
