yeah that doesnt seem like a fun job, specially if your changing valve springs.. probably need to strip the top of the motor.. un do all the motor mounts, and lift up the front of the motor so that you can pull the cover off and take the cam out. Im assuming its a hydraulic set up which is a lot easier cause you dont have to set the valve clearance. The most difficult part is going to be the work space in the front of the motor. hope you have a manual for all the torque specs and timing set up. Id help you but i dont have much time off.. i can come help you one day after i get off.. it would be like 6:00 though. let me know. im sure we could do it in 4-5 hrs.
