So, I have my front timing cover off and had at least two other front timing covers sitting around in the garage. For some reason, I got to really comparing the three them. I noticed that on 2 of the timing covers, the cam sprockets covers had a smaller groove than the cam sprocket covers on the other timing cover, if that makes sense. if not, here are some pics of what i am talking about. is this normal or are both of the cam covers with the larger groove damaged? thanks

both:


smaller groove:


larger groove:

 

 

here is the other side, is there anything that could be causing this?
