I replaced the lifters in #6.
The old ones looked fine.
Now #6 Exhaust is quiet.
#6 Intake still makes a tapping noise.
If I tighten the rocker the noise will quieten until the lifter bleeds down - then it returns.
One of the other Inliners sugggested that maybe I have a weak valve spring that can't shut the valve fast enough.
Comments?
Additonal suggestions?

Thanks in advance.
