This was more likely due to a failed oiler tube than it was the type of oil you used, especially if you changed it every 3K miles. The plastic clips that hold that tube in place get old and brittle and crack, and it stops lubricating the cam shaft. An oiler kit for both sides is about $6, and well worth the time you'll spend. Although it probably got replaced when you had the cam replaced. But did he do the passenger side?
