I’m in the middle of that myself. Most important thing: read manual about camshaft R&R. Twice. Then watch a couple of videos. Mine is the left (drivers side) which means I couldn’t remove the back cam tower completely. Pull all rockers. Pull gear Ang KEEP TENSION ON IT SO YOU DONT LOSE CHAIN TIMING. Remove camshaft tower bolts from outside to inside (one row doubled as head bolts). I stressed over the possibilities of these bolts being seized but they came out smoothly. Camshaft slid out easily. I sent my camshaft to Delta Camshaft in Washington - $180 including shipping (one lobe was chipped from a thrown rocker). Came back like new. Reverse for install. Use assembly lube. Might consider replacing upper guides at this point as well.My car runs great. But ... it sounds like a "sewing machine" with passenger side valve train ticking. I finally got my hands on a valve spring compressor and examined my rockers and cam today. I think I definitely found the source of the ticking. The #2 exhaust and #3 exhaust rockers are badly worn (obvious finger feel diagnosis). However, further finger feel diagnosis revealed that the #3 exhaust cam lobe also has a bad flat spot after the peak. Big bummer ... so I also need to replace the cam.
I'm a pretty good mechanic and I'm up for doing this work. Can anybody on the forums point me to a thread for cam replacement? Also, what are the best sources to get my new cam and other parts?
