I have not done the inspection with the screwdriver, but wouldnt the shafts already be set if I had the valve cover off and made sure cyl 1 was at tdc? Ive only done the stuff in the manual. I am sure that I messed up the timing for the dist. When I put the cams back in, I do not know how to adjust them since I don't have the electrical manual and have never worked on a vehicle with them before. :/ i will be googling to see how to so this. The truck starts after a few cranks.. Is it possible the truck is running this poorely with just that one tooth off on the cam sprocket? The truck did Idle a little rough before replacing the head gasket.
