1999 XJ. New head, new valve train, new timing gears and chain. My problem is at TDC (compression stroke) both of the valves are open. It almost seem like when I torque the rockers down 19ft lbs., the valves tend to stay open. Almost like the lifter(cam followers) are not compressing. I've cycled through each cylinder and used a borescope on each one. None of them are fully closing. What could be the issue. Maybe I'm doing the timing gear wrong. Lined up the two marks on TDC Cylinder 1. Anyone have steps on installing the timing gear correctly? New to XJs. TIA
