Average Life Span of a D-Max

[R.A.T.D.]

Can anyone tell me what the average life span of a D-Max engine is before it needs overhauled? How many miles approx?

[phale]

That all depends on how it has been taken care of and what mods. Also, which engine is it? LB7, LLY, LBZ, LMM? I have seen some that have went 400k with out a rebuild and seen some that needed rebuilt at a little over 100k.

We have a local parts/salvage yard that has delivery around most of the eastern US. They run quite a few dmaxes in 3500HD Stake trucks and 4500-5500 rollbacks and box trucks. A few of them are over 600k without more than regular PM, even original transmission.

250k might be a decent average IMO

Thanks for the info. Does anyone have some suggestions on where a guy could go to check on a rebuild kit for a D-max LBZ?

We have 5 dmax's around here and they have been great, minus some injector issues on the early ones.

Not one burns a drop of oil, even the 01 that must have 500k on it at least by now.

All in stock trim.

The truck in question is all stock and has pulled a trailer for most of the 200,000 miles on the odometer. Its had a head gasket let go for some unknown reason. Going back with a set of ARP head studs and calling it good.

I just had one in my shop the other day doing some maint. and it has 403,184 miles on it with a pretty good size tune on it from day one and has pulled a trailer everyday since new with draft horses in it all over the country...Nothing has been done except for a few injectors here and there....

they seem to last pretty good, im partial to the cummins though, i've seen 4 go over a million on virgin motors. but the Dmax is a durable motor, the key is to keep it maintained
