installing the timing chain the dots are not lined up right.i ended up with a new set and both it and the old one the dots are of by about half.if ive got this right the tooth on the crank lines up with the valley in the cam cog.im pretty sure its correct but why so sloppy with the dots.just checking to make sure.this engine is a learning experience.the cam bearing went in nice and the cam turns nice.so far so good
