This question is directed to those with EGR valves bolted to the throttle valve of their vanagons. When the engine was smogged the people at Fred's Garage (Menlo Park) put a smaller diameter washer to restrict the flow of exhaust gasses being returned into the system. This was done to a) ensure proper startup and acceleration without stumbling and b) to avoid the complexity and cost of replacing the valve ($200). My question is twofold: a) Is there any reason (other than a moral one) that the EGR valve should not be blocked off completely thus avoiding the hassle of replacing it? and b) does the EGR lower the temperature of the fuel/air mixture making it less efficient (than without one). I ask this because the Euro models of the Vanagons never had fuel injection and EGRs so maybe these engines weren't designed for this kind of pollution control equipment. PS Is there any place that sells EGRs cheap? Thanks in advance - DC
