My 04 Ram has 261,000 miles, it runs great but I'm wondering how long it will go.
It uses maybe a quart of oil between 7500 mile oil changes. Are these engines rebuild able?
Some say yes, some say no.

If you have got that many miles out of an 04 drive it till it quits,then buy a reman engine.

That's what I've been thinking, Thanks!!

The Hemi in my '04 Durango was running great at 135k miles. Left Home Depot one day, made a left at the next stoplight and it coughed and stalled. Popped it in N and cranked it back up, but it had a miss and was smoking from under the hood. Called my towing guy to bring a rollback, drove it on, started it up before we unloaded it at the house, looked at the engine from underneath and saw a hole in the right side of the block. I drove it into the garage to swap the engine. Number 5 rod broke and punched windows in BOTH sides of the block just above the pan rail. No coolant or oil leaks. I've got 2 other Hemis now, one with 217k. Same plan, drive it until it pops and swap it out.

I'm surprised you made it to 200k. I had an 04...the engine was fine but the rest of the truck wasn't. I replaced more parts on that truck than all my other trucks combined. I sent it down the road at 70k

Getting close to 130k on the 03 5.7 in my 55 Dodge pickup. Still running like the day I put it in. Only problem is occasional flooding on start when engine is warm. Put throttle to the floor and it starts. Probably computer related.

What happens on that era (2004-2006) Durango is that water runs down off the cowl and drips on the intake and when the engine has over 100k miles it seeps past the intake port o-ring and ends up in a cylinder.

It hydraulic locks that cylinder on start up and the powder forged rods break and sometimes split out the side of the block.
When I bought a really clean 2004 Durango that had done that is when I got educated on how often it happens.
Search the internet and you see it's pretty common, usually after a hard rainstorm.

My 04 has been a pretty reliable truck, no complaints from me. The biggest repair I've ever done to it was the oil pan started rusting pretty bad.

rusty oil pans have amazed me for some time, not just on ram pickups.
on a couple of caravans i have owned over the years, if one looks close at the paint when it starts to lift off the pan, it seems like a kind of powder coat, so ????

The only other time I had a rusted pan was on a 350.
The hemi one was double layer (maybe that says something) and would have probably lasted quite a while longer but you couldn't tell that without removing it and it looked bad enough we didn't want to poke at it much.

Had a 84 D150 318 tha was my winter beater in Michigan. After moving to Tennessee while changing the oil I noticed the pan had some rust pin holes in it and was leaking. Cleaned it real good with carb cleaner and spread Right Stuff over the bad area. Temporarily fix until I could replace the pan. Never got around to replacing the pan and drove that truck five more years before selling it. Pan never leaked again.

I bought a 2017 Promaster City with the 2.4L in 2020, with 120,000 miles. After the first oil change I replace the pan because it was so far gone. It's not unique to Mopars either. When I ran the local city vehicle fleet, we had all International dump trucks, both single and tandem axle, all with the DT466. After the first one got to be about 5 years old, I started keeping an oil pan and a set of bolts (like 28 of them in 2 different sizes) in inventory. Not only would the pans rust out, the bolt heads would rust away. We didn't use any of the high-tech ice melt products, just plain old salt from the Detroit salt mine. The rest of the undercarriage would still be painted black with the oil pan rusted and seeping oil...

The oil pan is much higher temperature than the rest of the painted metal undercarriage.
I guess it is the combination of hot, acid water and salt.
This is another spot where a replaceable “boat zinc” might be cost effective.

As much of a fan of stainless steel as I am, the salt would just create deep pits in a stainless steel oil pan.
