Hello everyone. I have a 1989 Honda Civic Wagovan, and just started noticing the water temp gauge reading hot. I pulled over and poped the hood and saw steam/smoke coming from the valve cover area. I let the engine cool,and looked at the oil dip stick. The oil doesnt appear to be milky,but at times I notice white smoke from the exhaust. Could someone please shed some insight on this issue. It would be greatly appriciated.
