engine noise

  1. lifter/tappet noise

    Alfetta & GTV6 (1972-1986)
    So my engine 2.5 V6 has a slight tappet clacketty clack noise, not too loud. I took off the valve covers and adjusted the exhaust valve clearances to .009 between the cam and tappets, I didn't bother checking the intakes being the intakes cannot be adjusted without shims. Is this noise normal...
