Life expectancy of a P7100

I know there are a lot of variables that determine the life of an injection pump, but I am just curious to see when other people have had to replace or rebuild their P7100. I have close to 200k miles on the original injection pump. I always use some type of additive to enhance lubricity and always keep the filters changed on a regular basis, but anything made my man will fail at some point. I have heard the p7100 pumps are very robust, but how many miles can one take before needing new barrels and plungers, delivery valves, etc?

Welp, there's a number over a million miles. A couple of weeks ago, I personally drove one that's over 800k. In fact, the STOCK AUTO TRANS in that truck is also over 800k! If that's not a record, it must be close. Anyway, pump life from normal wear just isn't a factor on these engines. Your hands will probably wear the rim off the steering wheel first.

I was reading about a taxicab in Greece with a Mercedes diesel P- pumped with 3.6 million miles on it.
Lots of parts had been replaced or rebuilt but not the P- pump.

That money would be better spent on beer. I had my IP repaired at 750k because of an oil leak where the throttle rod sticks out on top. Not one fuel lubed part needed replacement. I never use additives, but I do drink beer.

I never met a beer I didn't like, some just better than others.

Is it now....*rubs villainous beard while thinking*

What does the engine do when it randomly sticks? And how long does it last? Does it just vibrate a little very briefly?
