It’s a known fact that engine components need to be maintained periodically. In this day and age we have a “throw away and replace” mentality in which we’re taught to just replace parts and toss the old ones. In the early days of automobiles just about EVERYTHING was rebuildable or serviceable. For pennies on the dollar you could buy new seals and brake components, fuel pumps, etc. In those days being a DIY guy or gal was a necessity and not a choice.
