I'm currently trying to replace my valve stem seals and have to remove the Cam Position Sensor to do so. I can't find any info in my manual or in previous posts to explain how this is done. If I remove it, does it have to be re-clocked some how? The motor will be at TDC and I believe there is a mark on the body for the rotor portion, but how do I make sure the body is in the proper position? Thanks for the help!
