1. [Fot] Valve cover breather (score: 1): Author: "Mark York" <m-syork@comcast.net>; Date: Fri, 28 Dec 2007 22:58:39 -0800; Is there any advantage to add a breather to the stock valve cover on a TR3 or early TR4 engine?

I've always had a breather on mine so I couldn't say what the result would be of eliminating it, but I suspect the gasket might leak worse than it already does.
