I recently replaced all of the valves due to an oil leak breaking down and throwing the outer belt, wrapping the crank, and throwing out the timing. I'm ready to lock down the back of the cams and reinstall the cover and cams. My question is, is their a procedure to determine the proper crank position other than using the outer marks? I've read about removing the starter and inserting a tool and turning the crank back against it. I want to make sure the timing is all correct so as not to damage valves again. Any help would be much appreciated.
