Diagnosing engine sounds over the 'net is like sucking t*t through a cashmere sweater.

The cam and lifters are directly beneath the intake. You'd expect to hear valve train noise from collapsed or out of adjustment lifters up top- but there is no guarantee it's something else because all there is besides the valve train is loose wrist pin noise or piston slap. I suppose the cam bearings might be suspect, but that's a long shot. The distributor wouldn't make that type of noise and you'd hear it through the distributor body if it was.
