Yes, not all vtec-e engines get the valve cover. Mine, for example has the same vavle cover as the CX, even tho its a VX. Some VXs have it, some don't. And we're assuming its a year thing.

Maybe 92 and 93 doesn't have it and 94 and 95 do? My only reasoning behind that, is thats when they changed the front bumper paint scheme.
