I bought an 02 wrx a couple months ago and it has always had this odd clunking sound every second or so at idle, i narrowed it down to the passenger side head so i pulled the timing belt cover off that side and ran the engine. The cam sprocket was walking in and out of the head about .200" and the clunk was when the shaft would bottom out. So today i pulled the valve cover and everything besides the cam walking looks normal? i checked the torque on both cam caps but not the front one. what could cause the cam to have this much play? heres a youtube link to a video i took today with the valve cover off. Any help would be much appreciated!!!:(:(
