I know the early 2.4's had some cam galling issues, but they were few and far between. I was looking into my oil cap today for fun and noticed that the "roller" by one of the cams had some serious discoloration in the middle of it, it looks like it has been chewed up down the middle...here are the pics starting from a view of one of the cams, then looking over at the "roller". I dont know the name for it sorry. I am concerned about that dark streak down the middle. Now here is the catcher, I ran my fingernail across it to see if it was rough, or if it dipped down, but as far as I can tell its all smooth, just like the cam lobe. So if it is smooth, am I in the clear?
