Good old Bill

I should have said in last entry, to verify camshaft timing, you need to have access to the valves. Remove a valve cover, most likely it will be the drivers side that is the easiest. Removing that cover you need to use #6 cylinder for the check. Rotate the crankshaft untill air is expelled out of the spark plug hole, with the piston at the top, the ex valve will just close and the intake with just start to open. Again the piston needs to be at the top and one valve will just close and the other will start to open.
