My current problem is getting the crank bolt off..I've tried an impact wrench at 150psi and a 1/2 in. drive breaker bar. I tried locking the ring gear and still can not get bolt off. I can't hold the engine enough to break the bolt. Im basing the direction of the bolt by the engine rotation as CCW to loosen. I can't see the (bottom) timing marks until I get the covers off. To get the covers off I have to get the crank pulley off (bottom cover). Which brings me back to getting the crank bolt off. I have a water pump to replace along with the belt..I will take your advice and replace the tensioner also..thanks for the help.

John: I don't see how I can change the ignition timing, how is that done? I have changed it in the past by rotating the distributer. I don't think I can rotate this one or is it done electronically?
