thanks people, very good info! I think most likely from what I have heard we will go with changing them out to regular struts seems like a good way to avoid further issues, besides I think things might have been damadged when the car overheated badly (why we had to put in a new engine) a lot of stuff was affected we are only just finding out about, the car got VERY hot, melted the tail pipe, radiater, about cooked the tranny fluid...might have cooked something in the air shock system too:(
