Posted January 26, 200421 yr comment_65981 I think my 1978 L28 engine still has the EGR valve, according to the picture in the Haynes book. Does on the fuel-injected L28 engine need this? I could probably take it off, but it's supposed to be connected to a "vacuum switching valve"? I was thinking that I could block off the hole where the EGR valve was. Can I get some enlightenment? thx.At least there's no smog pump. Link to comment https://www.classiczcars.com/forums/topic/9911-de-smogging-an-l28-engine/ Share on other sites More sharing options...
