1967 Impala - distributor issue
I have a 1967 Impala, 350 small block engine, attached are pictures of my distributor. A few months ago I noticed some ticking when I accelerate so I checked with my mechanic, he said it was my distributor making adjustments and the ticking isn't/wouldn't affect anything. He stated the change in weather is what causes the distributor to make it's adjustments. A few months passed and I noticed the ticking happened every time i accelerate regardless of the weather (cold or hot). I couldn't find anything online stating this is normal, however I took my car back to the mechanic, we went on a drive and he said the ticking is the distributor making and adjustment due to the weather. He mentioned that we could adjust the distributor and get rid of the ticking, however it would have to be re-adjusted again when summer comes around. He mentioned that the ticking wouldn't affect anything so if i leave it as is then there wouldn't be any issues.
My problem is that it doesn't make sense to me - we live in California so the weather is pretty much the same year round. The ticking noise is happening whenever I accelerate regardless of the weather (cold or not). It doesn't happen when I accelerate in neutral or park. If this is normal and won't affect anything I rather not make any changes, however my gut tells me this doesn't make sense as it never happened when I first built the engine. I have about 25K miles on these spark plugs (and engine) so I thought maybe i should change the plugs, distributor cap, rotor and ignition wires to give it a tune up and hopefully fix the problem. Any input would be appreciated. Attached are pictures of my distributor. I'm just wondering if this is a normal noise like my mechanic said; if it is can I leave it as is (keep driving my car daily) without any issues, or should I be worried? I've taken 2 trips cross country with this noise and had no issues with performance or gas mileage.
p.s. wanted to mention that the more I accelerate (higher RPM's) the faster the ticking gets - and if I leave it on a steady pace of acceleration the ticking goes away, however if I increase acceleration (RPM's) it ticks again until I leave it at a steady pace.
