if i recall i have seen my uncle on some of his personal cars do it, and he did something a lil off the manual, he lossened the crank pulley, and the he also used those zip-lock things and he tied the cam gears to the timing belt so that he didnt have to completley take off the camgears or the belt, sorry but dont remember what he actually did but i think he was replacaing the head gasket since his car kept on spitting coolant onto his windshield, and this was done to his turbo si.. thought it was preety handy...
