No. They only did the drivers side. However, they did have both valve covers removed. I know this as they were not reinstalled properly and I had to take them off and redo them myself. When I had them off, I did inspect the entire valvetrain, and everything is tight on both sides so I think it is ok now.

It is possible that the cam was just old and worn out. I am certainly not looking to go after them for the cost of a cam. I am just trying to get to the bottom of whether or not SM and SL rated oils are a problem for engines with flat tappet cams.

Anybody else know anything about this?
