I had burnt smell coming in through the a/c so got it checked by local auto repair. They said it was valve cover leak which I got repaired. I went fro second checkup today but they found that now the lower valve cover is also leaking and oil is filling in the oil pan.
My question: 1. When the valve cover leak is being repaired , do you check all the valve covers for leak and was this missed?
