My 1981SH had the smootheset running engine ever for years then I shimmed the valves(a procedure I have done annually for years) and it picked up a loud ticking noise after it has heated up.Cold it is like it always was,after running for about 10 minutes it starts to tick.My auto mechanic thought it to be a pin hole in the inner lining of the original double walled exhaust pipes.However the tick seems to be coming from #4 exhaust.I am certain it is in the valve.Any ideas on how I queered it while shimming and ideas on the fix?
