OK I have this s80--2.9 non turbo. head off replace valves. and remove cam gears. I did'nt do the tear down.( Yes this seems to be the prob.) what site can I go to to find detailed info on the dissasemble and reasemble of the cam to gear. and how to set the valve timing.( I have read all of the posts here and am not getting all of the info that I need..) all of the posts and info here deal with replacing a belt that has not broken. I need to start from scratch. PLEASE HELP. this car is tying up my stall for to long. ( not to mention last night somebody droped a tire on the fender, It goes on, and on, and on.)

 

What year is it?
Maybe this will help.
