Ok I found an engine on eBay that is SUPPOSEDLY a H22A Type S but when I look at it, it has a black valve cover. This is making me think its a standard H22A, still I am interested in getting it cuz its in my area like 30 miles from where I live, so anyways here is the question:

Do ALL Type S engines have a red valve cover, is there any other way to check if it is a Type S aside from checking the HP and such? Thnx
I mean external look and stuff, does the Type S engine LOOK any different from the standard H22A?
