In days gone-by: You pulled your plugs, cleaned and gaped them every time you dressed and gaped your points and set your dwell.
(about every 30000-35000 miles)
So you replaced the crush washers every time you cleaned gaped and reused your plugs.
Back then the washers were very easy to come by. I would have 20-30 in the tool box.
Not easy to find them now days.
I have a schedule for all maintenance items on my cars.
But I also let the car tell me what it needs.
Example:
I have oil changes on a 5000 mile schedule.
But if the oil is discolored or dirty when I check it with only 2000 miles on it I change it.

Perhaps there is a business opportunity there - sell crush washers on Amazon.
How are you checking the oil discoloration? There is not much oil on the dip stick. From the filter housing maybe?
