2500 Burb Advice

[HoodRich]

After reviewing my situation, (wedding in June, still in school 2+ years left, and practical needs) I have decided that I would really like a 2500 Suburban as a DD/Tow rig. I know it won't pull like either of my fathers cummins trucks or a superduty but it will be better than driving the k5 to wheel. I am posting here because I want some serious opinions about choosing between the 454 and the 6.5, it seems the 454 should have more power although worse mileage towing and as a DD. Considering mileage, mpg (towing and DDing) and longetivity of the truck which of the two would you look for?

Diesel. Better for both DD and towing.

Yeah, diesel. My 95 had a big block tbi engine in it - what a turd. Swapped it for a blown 6.5. More power and picked up about 7 extra mpg.

I'm looking at two diesel burbs right now both 95's one with 144K and the other with 172K. Whats the life expectency on these with routine service? Any things to check on the 6.5 right off?

My parents had a half ton when I was younger, but they had problems with the injectors or something, someone who knows more about them could maybe explain this further.

The injection pumps are somewhat problematic, but I doubt that at over 140k either one of those two trucks have the original. With good maintenance, they will pass way beyond 200k. Don't be scared by what looks like "low" oil pressure at hot idle, 10 psi is not uncommon. As long as pressure rises with RPM it's fine. At that mileage I would consider new nozzles and glow plugs, along with the normal filters and fluids.
