How many miles can it go?

JJgreenD · Dec 22, 2017

Well I have a 2000 5.9 D with 239,907 miles on it. So how many miles can I expect to get out of this engine.
OK I know there are many factors involved with this question. Like regular maintenance. But how well is this engine built?
I have put some repairs on hold as not sure if it will go the distance. Thoughts.
and Thanks.

My 2000 is sitting at 255k and still runs strong. This is despite having to change head gaskets over the summer.

my '98 has 212K+ 4x4 and will still light the tires at will , anyone interested I need to get rid of it,multiple consecutive seizures have left me w/o the use of my hands and I just got 6 months to a year to live so I wanna head back to the Rockies about 13+kft to die in peace, will use money to get medical equipment and fix trans in 88 Burb XL w/ Travel Quest custom interior oak package. I will miss my 4x4 and hate to drive a bowtie but its cheaper to drive 610 miles to tank vs 357+ in Dodge. Unless anyone has any other ideas, open to suggestions.

We had one gen1 that I believe hit over 400k miles.

New goal to achieve with mine now...400k miles before I pull the motor and rebuild it.

Thanks for all of your comments. If I Could get even 100k more miles out of it, that would be great. It does burn some oil but not at a fast rate and the engine still has some get up and go. I did tow a small travel trailer for a few summers before I sold it. so over all my D was not under to much stress. The transmission was rebuilt at 100k so I think i'm good there.
The one main issue I have is the exhaust manifold has a leak causing it to run rich. I'm thinking fix it.

They're a good design. So were the magnum 3.9L V6. Construction standards used to vary a lot more than they did then to now due to assy line automaton, but for any engine from anybody but Toyota, I'd say anything over 200K is wonderful. Toyota's 22RE 4-Cylinder of the last decade was one of the best engines in the history of internal combustion. Generally-speaking, they literally had to be abused before they'd grenade with less than 200K on them. I think they're sill in-production today, but not 100% sure about that.
I'd just keep up the meticulous maintenance it's obviously gotten, and keep on truckin until ---

Compared to how much we had to do to our v-8's prior to 1980 or later we have come a long way. Valves needing to be ground at 50k, timing chains needing to be done at 45k, engines that the manufacturer said to bring back in if it didn't use a quart of oil every 1000 miles. And let's not forget our wonderful interference fit 4 cylinders that made you rebuil the engine after blowing a timing belt/chain. I pretty much think that our new engines are extremely reliable.

My D1 ('99) has 268K miles, and is our backup vehicle (though it's currently sitting with a dead battery). It seems that the engine (5.2L V8) will outlast everything else on that vehicle, and still runs quiet and smooth. Since getting D2 (2017 SXT) earlier this year, I promised the Spousal Unit that any repair on D1 over $500 would be the end of it. It will be a sad day indeed.

The engines will make 400K....but most likely the trans will not.

Good to know. Thanks

I have a 98 Durango that ran to 195,000 miles and it started losing oil pressure. 5.9 or 318ci. At first I thought it was a bad sensor but the engine failed rather spectacularly after about 6 months of the oil pressure showing 38 psi then dropping to 0. I found out that oil sludge is a real problem with this engine.
I had the engine and transmission rebuilt and it runs great. I also rebuilt the frontend and ac system. It drives like new again. I did have them put in a higher performance oil pump and the oil pressure is slightly higher, and the pump delivers higher volume.
