I pulled the valve cover off our 1996 Cavalier last weekend to replace a valve cover gasket. I thought I'd share a picture of the cylinder head. The car has 168k on it; my wife bought it new. It received dealership dino for the first 15k miles, M1 for the next 127k, then TropArtic for a couple of years, and now it's on rebate special ($1/qt) Maxlife synthetic. It sure does like that Maxlife synthetic...nice & quiet! Engine still runs very well, and I hope to get another 5-6 years out of the car.
