[Chevelle-list] Ticking from #4 Cylinder :-( (addidional info)

[Pelle Andersson]

I did the stetoscope thang and located the "source" to be under the valve 
cover!
No arching from the ignition cables found but I'll swap the plug with
another cylinder to rule out cracked spark plug insulation.
A fellow gear head on a Swedish list thought it might be a stuck valve at 
#4?
I'll check and adjust the valve lash on all cylinders today to rule that 
out.
