Why do you think cat went with acert. Egrs are bad. It is inevitible that all will have them. Sorry to be the one to inform you though. They are detrimental to engine longevity. It is a fact. Not speculation. Give it a few more years.

 

A little about egr.
"can cause valve train wear, filter plugging, bearing failure, sludge formation, fuel economy loss and reduced engine life. "
"but they also introduce corrosive acids (e.g., sulfuric acids) from sulfur in the fuel and nitric acid into the engine. Likewise, the change in flame characteristics along with the recirculation of exhaust gases cause increased soot build-up in the crankcase. "
It gets better.
"Several SAE papers have shown how Soot contributes to diesel engine wear. One of these papers points out just how sever the problem of Soot in today's engines is. According COMO paper EX1, Soot will enter the lubrication oil at the rate of .0048 oz for every gallon of fuel burned. A truck will burn 1,786 gallons of fuel every 12,500 miles, at 7 mpg. During this 12,500 mile interval, more than half a pound (8.75oz) of Soot will enter the oil."
"Diesel engine manufactures face the prospect of having to REDUCE their drain interval recommendations significantly because of increasing levels of Soot, caused by the need to introduce EGR."

You seen that luberefiner thing. Might be time to invest.

Cat went to great expense to get around egr. Even to the point of paying a per engine fine while they were developing accert. They know it will shorten the lives of their engines. They did not want their customers to pay for cleaner emissions at the expense of engine life.

 

Less not bump the language filter....from the Gudielines:

 

Im glad you said something. Cause I have a copy of the epa guide in front of me. Let me see. Oh yes. 300 16 city 21 highway. 302 13 city 17 highway. Another app had them at 16/19 compared to 12/15. So yes the 300 although almost identical displacement got better fuel economy than the 302. Thanks for making my point for me.





Heavier crankshaft ........... A shorter crankshaft is heavier?

More valves per cylinder ........ What? It has more than 4?

Higher thermal efficiency (key to CO2 reduction) ...... ???

The stiffness of the block for torsion and bending is tied to the overall noise of the engine. The PSD has the advantage here, and thus has less radiated noise. ...... The cummins is quieter at idle. I read the tests when they were first released.

I found this and thought it was a little weird.
Looks like it was written in about aug of 02. So theyve sold another million in the last two years. Must be a misprint.

 

[QUOTE=Marine Ironman]That's 3 PSD owners. Any more? drop a short note, I'd like a head count.[/QUO

PSD OWNER LOUD AND PROUD--THE dodge boys gotta talk to my tailpipe--they never can seem to get past it--NOT EVEN WHEN I LET THEM GO FIRST--the little dodge boys and their little dodge toys

 

If it were me, I'd take a PSD with EGR that "only" goes 500,000-600,000 before a rebuild rather than a smog billowing CTD that can go 1,000,000 before a rebuild. All the while, I'll be passing the CTD's by as I run up and down the interstate. Heck, by the time I put 200,000 on a vehicle I want a new one anyway, (well, except for my Landcruiser 302,000 miles and counting). Always something bigger, faster, and more efficient as newer designs come out.

 

Hey I drive a psd but I don't think I want to get in the middle of this arguement. But he is right I have never been past by the locomotive Cummins,need it be towing or empty.

 

So what happens when the Dodge truck falls apart around the engine? Do they mount seats to the engine itself?

 

I still have yet to see proof of all these rams falling apart around the engines guys.

 

I've driven one and have seen plenty of "classic" Ram/Cummins trucks on the road. The truck is shot long before the engine. The one I drove had just over 200K miles on it and both the interior and exterior were shot. The second transmission was slipping like crazy and it handled very poorly.

 

Classic as in '89-'93? How about '94-'01? The only real complaint I hear about them is the trackbar on the 4x4 because it is the same on the 1/2ton and 3/4 ton, I have never actually taken the time to look at the bar on the 1tons but I am gonna guess it is the same too.

 

With the exception of some 2 cycle Detroits (no longer made) and 3408 Cats, most over the road trucks have the tried and true inline six, not a V-8. Whether it's a Cat, Cummins, or 4 cycle Detroit, they all can make over 500 HP and 1800 ft/lbs of torque. Sixty years of experience and experimentation can't be wrong.

 

And those engines are also mated to a much larger transmission than the one Dodge uses. They don't even offer a 5-speed auto with the Cummins like Ford and Chevy do. The powerband of both the PSD and Duramax coupled with their respective 5-speed automatic transmissions are why they are a better choice in a light duty truck than the Cummins. Just because something works well in a medium or heavy duty truck does not make it the best option in a light duty truck.

 

I think everybody here arguing this topic has their own opinion, which is all that should matter. Neither of the three diesels are THAT MUCH BETTER than the others. They all will tow up to the vehicles maximum capabilities better than any of us need them to. So what the PSD gets there 5 minutes faster. Big f***ing deal. The simple fact is no matter what you choose it will be a good choice. All three of these engines will outlast any gasoline engine. If all of them were not good diesel engines they wouldn't be being mass produced for the vehicles they are in. So I say if you want a Ford, Chevy, or Dodge get what ever the F**k you want. I prefer the Cummins, and others may prefer the PSD or Duramax. It does not matter. As far as the chassis that the engine is in, as long as you are not a jackass and you maintain it like its your pride and joy it will last you a very long time too. The Ford looks great and I think the Dodge does too. I don't like the Chevy that much, but somebody else might. Whatever engine/chassis you choose it will work for you better than you even need it too. So everybody needs to quit bringing up stupid reports on whatever engine they like. It is ridiculous.

 

I have more buddy's who have had there Dodge Tranny rebuilt then I got fingers! What good is a Engine if there is no tranny to push it. Dodge had always had tranny problems dealing with High Torgue engines. Just look at Dodges recall on both Gas and Diesel.
