Now that sounds better, you're giving your opinion and somewhat of a reason for that opinion. But to say that the Cummins is the worst engine is just plain silly...If I could have my way I'd have a Cummins in my Ford though...

ha, not that i think about Duramax is probably the worst. Cummins conversioins for Ford are expensive

 

See, we do agree on one thing.

I want the cummins in my ford from the factory...

Tim

 

You're just splitting hairs there...

I also personally know people with close to 900000 miles on there Cummins engines...the truck's fell apart around it more than once, but the engine is still running strong. I also know a guy with an older 7.3 idi that has a little over 750000 miles and it's pretty much all original (he's had little things go wrong, but nothing major) and he still does some hotshot runs with it...

Ya i can see that. i guess its based on personal expierene with the engines. nad yes we can agree that the Dmax blows

 

You think about it Cummins has got a few bad engines.

Their V-8 engines were never any good the L-10 Cummins wasn't that great the 444 Cummins was horrible the ISX Cummins isn't that good the ISC has problems the M-11 had electrical problems. The class 8 engines that Cummins had were the 855 block like the 350-400 small cam big cam and the N-14 Cummins.

Caterpillar has and will always be number 1 choice in class 8 trucks the 3406A wasn't the best but the B,C,E were all good the C model had some problems but nothing too bad. Caterpillar is number 1 choice for marine applications too.

The 5.9 Cummins is way over rated its not a good medium duty truck engine they barf their guts pretty quick. They were never designed for a medium duty truck. The only reason you see them in a medium duty truck is they are cheap engine option. If you went with a Cat 3126 it costs you a extra 2-3 grand more. Cummins engines are not cheap to fix in Canada a rebuilt V-44 Injection pump on the 24 valve engine is pushing 5 grand. A rebuilt inline pump is 3500-4000. You get the 24 valve engines with the bad fuel pumps there is 300-400 dollars a pump.

The 5.9 Cummins usually gets 200,000kms (125,000 miles) in a 5 ton truck and it needs work. The utility companys used to run old International trucks with 6.9 and 7.3 power and never had any problems with them. Usually have 300-400,000kms on the original engine.

The Cummins is a light duty engine just like the PSD and Duramax.

 

Cat engines in the F650 are sweet

 

The Cat engines in medium duties is the 3126 or C7 Cat the smallest Cat engine used in trucks.

 

They're like a 7.2 or somethin. pretty tough engines

 

The same engine is used in light tandem axle trucks usually found in Freightliner FL-80s. Gutless wonders but they do the job.
