average life of 2.5 diesel

Does anyone have an idea of what the average mileage for a 2.5 diesel would be before it's time to rebuild. Mine has about 350,000 miles on it, it takes forever to get up to speed, and anymore it will not climb the slightest hill without loosing speed. It acts like it has no pulling power or torque at all. Thanks for any info you can give.

2.5l from early 1990's ?
You heard that the Thessaloniki cabbie logged 2.4 mil miles on his 4 -banger diesel from 1980's?
As far as I can remember the engine was 121 HP rated. Adequate for flat driving, but with nothing to spare in the mountains.
If you have lack of power start with rebuilding injectors.

Given your car's symptoms, it's obviously time the "rebuild" something.
