Engine/Transmission (1998.5 - 2002) Are we just adding "sand to our oil"????

If you live in the "salt belt" the last thing you worry about is the engine burning up regardless of your HP

Rusty, yeah, I am not saying it makes them live longer, but most of the time we are just driving. And if we get the power we need at lower rpms, then, on a daily basis, we 'shouldn't' need to rev the motor as high all the time.

On the other hand, because we have more power, we tend to rev it out more to have a little fun now and again. Some people more then others obviously.

Gary,

Earlier models may have been rated at 300,000 mi. , but we've all heard of 1,000,000 mile motors. I don't care what they say, the earlier, lower horsepower motors with larger turbos and lower egt's will last longer IMHO.

Question;

Has there been a million mile 24V yet?

Yes there is a tread running some where here!

At my current rate of travel, I'll be 76 years old by the time my truck has 500,000 mi on it or 116 years old by the time it has 1,000,000 mi. If my engine only lasts the 400,000 mi that Gary suggests, I'll be 68. I'm really not worried about my engine wearing out.



I'm going to treat it right, use the right oil and filters and change them often. I'm going to get a pyro and use it to control max EGT's and for cool down time when necessary. I expect it to last a looooooooooooooong time.

Fact is, I usually get a new truck every 3 years or so, but this time I'm telling myself that I'm keeping it forever!

WELL, it's the SAME Cummins who publicly stated the *normal average* life expectancy of the older engines was 300,000 miles, and has also now stated the newer engines, due to improved design and materials are good for an additional 100,000 miles - or 400,000 average...



Sure, we know SOME go lots farther - some less - but why would we believe them on their FIRST claim - but NOT the SECOND?



Put another way - if SOME of the earlier engines managed a million miles with decent care and operation, should we now call Cummins a liar when they make a claim that indicates the same circumstances will allow SOME of the newer engines to go a million and a quarter miles?

Are the 300K and 400K figures being quoted the B10 overhaul life? If so, that just means that 10% of the engines require overhaul at that mileage - 90% don't!

The milege figures quoted earlier applied to pre-'04 Cummins - I see they have a new spec for the '04:



======



The 2004 Cummins 600 Turbo Diesel builds upon this durability with:



Average of 350,000 miles to overhaul.

Proven technology: most components are carry-over, including the Bosch high pressure common rail fuel system optimized by Cummins controls.

In-cylinder combustion and diesel oxidation catalyst solution requires no exhaust gas recirculation components.

Gallery cooled high-strength aluminum pistons for durability and long life to overhaul.

Premium high strength inconel exhaust valves and high-cobalt stellite exhaust valve seats for durability and long life to overhaul.

High strength exhaust manifold with multi-layer gasket between head and manifold.

Forged steel fracture-split connecting rods.

Apparently, in this case they have reduced O'haul figures from the former 400,000 mile - but still better than the earlier 300,000 miles on earlier engines...





Glad *I* got one of these HIGH-mileage '02's!
