Wow! I just replaced a leaking valve cover gasket on my newly acquired
97 camry (4 cyl) and I was shocked at how filthy the overhead was. There was lots of burnt oil everywhere and the inside of the valve cover looked horrible. Lots of baked on oil. It looked like oily carbon deposits on several of the components (non contact parts of course). I cannot stress how important it is to get oil changes often and keep the oil level up. This car was run for 9,000 miles during one oil change and I know if frequently has had extended intervals in the past. I still runs strong, but I have seen plenty of overheads, and none were as ugly as this one. In fact my '90 corolla looked shiny and new inside.- posted
