The reason why my civic was stalling and what not was because it was out of gas. The gas gauge is broken so even though it looked like it had a quarter in it really was about empty. I'm still selling it though because everyone who owned this car abused it and I am not gonna drive an abused car. The valve cover and gasket is sealed with some clear stuff (I can't think of what it is now). Who does that? I gotta get rid of it
It can be fixed, but it might be more expensive than what you want, the clear stuff was probably rtv sealant, if they were to do it right it would have been black. That is what permatex calls "the right stuff" it's a gasket maker/gasket in a can, works really well.
