I would agree as others said lifter collapse or rocker loosen along with what does the cam lobe look like.

yes poly lock was still in place..when removed i left set screw in original position and reassembled with 3/4 turn on lifter..collapsed lifter?? brand new crower rollers..
thought maybe something went through and held the exhaust valve open, but you think you would have seen damage in the blower..would like to test run the motor again but scared of breaking something..
