My daily cts valve cover had a small leak, decided to start the VC gasket replacement tonite. I only had time to do the passenger side as I was watching my Dodgers punch their ticket to the World Series 👍. The previous owner had local dealership oil changes with M1 per the reciepts. I bought it w 114k miles, it now has 126k miles and I did 3 oil changes (approx 3k miles ea) in that time using smitty syn blend 5w30. I think it looks good.
