Well in theory any intake leak will affect all cylinders since it disturbs the amount of vacuum. Only a fuel injected engine would not notice very much. The only noise I hear now is when I turn it over by hand there is a loud SNAP every other rotation. If I dropped a valve seat that SNAP is probably the piston hitting the valve. More to come.
