Well today I found out that it is hard to source the Cam Sprocket holding tool thing.... Which in turn makes it hard to remove the cam sprocket bolts with motor in car (taking off the valve cover in car can suck).
So the trick I figured out today was take your old timing belt wrap it around the sprocket and have your lovely assistant hold tight. At this point you just give a quick whack on your wrench and it should break the bolt free with out turning over the cam
