I hope you do make it to a million miles but I'm a bit skeptical. A lot can happen in the next 645k.
In my experience, compression is in the low 300's around 300-330k, sometimes dipping below 300.
But i am happy that your's is still doing great and hope it makes it

I thought the same thing so I checked my valve adjustment when I put my glow plugs in at 250,000 and it didn’t move at all still where it’s supposed to be when the motor was brand new so I did a compression test and it was well over 300 it might have been 400 I forgot it was so long ago all I remember is was well in spec. and I checked them all.

New to forum here and was looking for any help.....

I have always wanted to buy a 99-03 7.3L and now I am in a position that I have the ability to do so. I am patient and would be purchasing a "Grandpa" rust free truck with less than 150k. The thought process being that it would last for a long time still and I wouldn't by anymore trucks.
I would be just using around town and to trailer a smaller center console boat locally (5-8k miles a year). I know the history of running 300-400k+ off the lot however,

My question is how long will a 150k truck today last given the appropriate maintance is done. Will everything else fall apart? Are we realistically thinking 10yrs, 20, 30, forever?
I understand its an old truck and stuff will pop up, but I don 't want to be in the shop every month 5 years from now just because it would be a 30 year old truck.
Curious to here your honest opinion which will help my decision to purchase.
Thanks in advance

I have a 2002 I bought brand new and I have 355,456 miles and still going strong I believe I will get 1,000,000 miles no problem out of mine and I tow a lot of that answers your question.
