Congratulations on the new rig.
Have to ask what attracted you to the literally worst engine built for light duty trucks in the last 20 years?
Especially given your recent engine issues….

Because those issues are now well understood and there superior fixes for all of them. It is now easily, with time and money, turned into a very reliable engine.

not the worst by far, as long as they are left stock. problem came in when people hopped them up and didn't do other things like stud kits and such. I would still take a 6L over any 12V or 24V dodge 😉

The weakest points with both engines is the oil cooler which can be addressed by a coolant filter so the cooler never cloggs, or an external oil cooler which works better anyway, and adds 2 more quarts oil to the system. The other major fix is an improved egr cooler that's less likely to clog, and also not crack and leak coolant into the exhaust, or exhaust into the coolant. There are other repairs beyond that but these are the main two.

We really need a roll eyes, head bonk, type emoji for responses like this.
But I gotta say, u Frod fans sure are a loyal bunch. OMG. Defending a 6.0no is like idk, can’t describe it.
Sure some ran/run without lifting the heads, blowing the EGR or oil cooler etc. But even those are still orders of magnitude more finicky than the competitors.
And to the “I know of 3 of them running strong to this day….” comments, I can only think back to oilfield work up on the Slope when companies were trying to baby along their pre 07 diesels due to the problems with emissions and idling extended periods. So one of our partners had a fleet of “old” 6.0s and LB7-LBZ GMs. Because Dodge didn’t make a crew cab and their transmissions sucked.
Roughly equal numbers of both brands.
On one side of the shop there were 2 or 3 engines lined up. Like 1 new and 2 blown. Those were the Dmaxes. On the other side there was like 20-30 6.0 Flowerjokes lined up. Like 20 blown and 10 new for the next 10 Fords that ate themsleves.
No other explanation needed…..- Camper_Jeff___KApr 14, 2025Navigator
I do kind of like the name PowerJoke. You can continue focusing on the negative pointing all the dead engines you saw, but I will bet you, if each of those engines top ends were rebuilt with updated Bulletproof parts, they would all be reliable 500000 mile engines going forward. I will guarantee you, none of them had a failed bottom end rotating mass unless it was due to failure of another part like the oil cooler.

My nephew has three of them working daily for his landscape business without issue. There have been some deletes and other work to make them better. He's had no problems with them under his ownership. My friend was a fleet maintenance manager with a couple of them including his own company truck being 6 liters and those worked well as service trucks. There are so many improved performance aftermarket parts for the 6 liter. The 6 liter is also considered to have about the toughest bottom end of any diesel in it's class. Most failures happen when somebody chips the engine to get higher performance. Leave the tune of the engine alone and it will run for years
most times

Nice low milage for the age, that would be a 25K or higher truck up here. that motor should be perfect for hauling your camper.. you'll get better fuel milage also what's the height difference between your old truck and the bed of the new one?
I don't know about the bottom end thing, ill have to read in to that and take your word on it, but they did have the weakest head bolts out of any ford diesel and that's where the issues always came in, to much power added made to much cylinder pressure and then you blow head gaskets. a good after market stud kit fixes that, or just leave it stock. the 6L was a ok first attempt for a 7.3 replacement but it fell short in a few areas that's why it was short lived and the 6.4 was brought in. the 6.4 had issues of its own, but when deleted and tuned it was an absolute beast of a motor, but the 6.7 came out and is going on 14 years now with only updates and no major redesign.. any of them in stock condition are capable of hitting a million miles if taken car of, and if built properly any are good for power and lasting. personally the 6 and 6.4 didn't have enough of a benefit to entice me off my hopped up 99 7.3 diesel , but my 2014 6.7 blows that old 7.3 out of the water, even though the 7.3 had more torque and HP than my 6.7

Dave's auto repair on YouTube says the main trouble with the 6.7 is the oil system. There is a long pathway and the crank is the last in line to get oil. Says it's his most common failure with the 6.7, spun main & rod bearings. The 6.4 which had the 4 headbolt problem too, and the twin cascade turbo which was problematic.
Hopefully, this truck and engine will behave.

It is a nice looking truck. Best of luck with it. Hope you got a good one.
Just not a gamble I’d take, given the multitude of options that have a more reliable engine.
PS, delete is not the right word. Nothing to “delete” except maybe the cat which isn’t one of the known problems aside from the same potential as any other engine.
EGR, idk what the popular thing is to do with them on a 6.0.
However upgrading all the typical parts that grenade is maybe what you’re referring to. Bulletproofing the 6.0Kits are only about $1600 and way back when I read that you can get the heads off without removing the cab. IE it is possible to bulletproof the heads without a vehicle lift.
possible but not fun. If this one ain’t bulletproofed it’s highly recommended.
The HPOPs also really like clean oil. And they really don’t like extended OCIssafe travels!
