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

[Pelle Andersson]

I adjusted all the valves today & the ticking disappeared (but returned
slightly after a while).
I think it's the "lock nut" on #8 cylinder that's unthreading it self.
Even though I thought it was #4's valve that was the problem.
I dont know why the sound dissapears when i disconnect #4's plug!!??
Maybe both of them are causing noise?
