The timing belt on my S83P EF-CS recently broke and I’m working to get it back together. I’m fairly confident I have the timing marks on crank and cam correct but I’m not getting any compression in cylinders 1 and 3. Cylinder 2 is about 130PSI so I’m worried I may have damaged valves when the belt snapped. I know they are technically interference engines but I’ve heard its unlikely to get valve damage because the valves retract in the head to the closed position when the belt breaks. Any advice on whether bent valves are likely my problem or if it could be cam/crank position?
