Both of the above are ture.
Reaming the carbon out will increase the Glow Plug life and a worn Engine will carbon up more than a new one.

Also Injectors with worn out Nozzles will shorten Glow Plug Life (and cause more Carbon build up).

Older vehicles need more maintenance and work to keep them going.

Rebuilders: I removed my Alternator to replace the Bearings. The sticker on the Alternator said "Rebuilt by Bosch North America". The bearing that went bad was made in China. So I conclude that Bosch is using the made in China Bearings during the rebuild.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

I believe it's impossible to always know why a part fails and goes south. Much of it can be attributed to unidentifiable lower grade OEM replacement parts, versus brand new parts that were used to manufacture the car. I also believe that upline and downline parts degradation is very real, and a common reason for multiple, domino effect parts failure rates. That is, you replace one part or component with a stronger part that causes failure in interfacing parts or components. There is also another reason why things fail other than overuse, and that is underuse. Mechanical things do not work as well when they are not used on a routine basis - whatever routine is to you.
