View Full Version : Dodge motor reputations

I am going to look at this really nice truck tomarrow. I know its a 1998 dodge ram 2500. I don't know if it is gas or desiel yet. Could someone give me some backround on both gas and the desiel engines from that year of dodge truck?

If it's diesel, from what I've hear, buy it tomorrow! I want a Cummins so bad. The gtassers are not bad either. They are pretty reliable, even my 1987 Ram and my dad's Dakota. I don't have any complaints. Just watch the tranny and the brakes can be crap sometimes as well.

i have heard many horror stories from the transmission tech at the dealership i work at. he was a dodge tech for many years and doesn't have much confidence in their product. i have also heard of sludge problems developing in their engines. like anything mass produced, you get totally bullet-proof ones as well as complete lemons. i do sincerely wish you well if you get it, and don't forget to ask to see maintenance records.

No problems here.

HUGE difference.

As stated, if it is a Cummins and the price is right (about 3-4K more than a comparable gasser, mileage matters not) Jump on it.

I have a 2001 and you would have to pry the keys from my cold dead hands (unless I were trading on a new one that is!).

The gassers are junk just like all other trucks, prepare to replace it ever 160K or so........

The 5.2 and 5.9 gas engines have been around forever. I've never heard of anyone complaining about them except that some wish the 5.2 had more torque. I'm pretty sure that diesel engine in 1998 was the last of the 12V with mechanical injection pumps. It's a great engine.

Sludge in the engine is almost COMPLETELY dependant on the oil you are using. I know a diesel tech and he says he will never work on a marine diesel that has been running delo for awhile because so much sludge will gather on the camshaft and crank.

The 98 model year if it is a diesel was one of the best years for the 12V mechanical injection motors. If the price is right buy on the spot. Cant really comment on the gas motors too much but as stated above they will only go 160-200 thousand before replacement is necessary.

There are 98.5's that are the 24V with the newer pump. The 12V (non VP-44) are very hard to come by. Properly tuned, a 12V Cummins can get over 23 MPG all day long.

Gassers trannys are junk!!! Some have lasted a long time with lots of miles... however there are more out there that have or have had some type of problem. I personally know a guy that went through 2 in the same truck, he had a heck of a time selling the truck... but he was honest with people. Truck was sweet except for the scrap they call a trans.
I know the neons early one had trans problems also... I had a few friends that worked in the dodge factory in Kokomo IN, so i've heard some horror stories myself.

I am a Mopar Nut I have had Two Rams and no Problem with them I made sur that I service them just like the owners manual says to do. My first was a 96 and it had 210k when I trade it in for a 2004 Ram Hemi and I have enjoyed it too. If you stay of the pedel you can get some good milage, but if you got a lead foot you better get a Chevy or Ford. I have 45k on my 2004 and still have the same tire son it. I am a MOPAR NUT so that is my two cents. The cumming is suppose to be a good engine and I have been told that 50k miles the engine is just getting broken in. :cool2:

The 5.2 does need more torque. It is one lug of an engine. Like any other brand and series of trucks, the diesel is almost always better than the gas. Most people would rather have a diesel than gas, but you have to be able to afford it. dodge is no different. The Cummins is the engine to beat and nobody comes close!

i cant speak much of the older models, althought I have heard of transmission problems pre 2003 but the 5.9 is a reliable engine. I had a 2003 2500 with the 5.7 liter hemi.. beat the living piss out of that truck, pulling 12k lb trailers and not babying it, plowing with a pallet of salt in the back and 3 passengers. Engine held up well.. had to replace the usuall suspension items but you'll have to do it with any truck. I wish i never got rid of the truck. If you can afford a diesel its basically bulletproof but i would recomend the following..

Ford Diesel 7.3L 2003 and earlier
Dodge Cummins - 2001 and higher.. although the pre - 1998.5 are not computer controlled so mods are a lot easier.. feel free to contact me with any questions

Absolutely stay away from any Chevy diesels pre Duramax.. they are known for being very costly..

As far as Gas

Ford 5.4 very reliable
Dodge 5.9 reliable but poor gas mileage
Chevy 5. 7 - from what i remember alright but was beat after 100k

In my experience, if its a Cummins diesel, BUY IT IMMEDIATELY. those motors are powerhouse BEASTS and will work very hard. I've seen one towing what I swear was a 30K pound boat once, no problem, acted like it was a happy machine doing so too. this was a company truck, so I can bet it was stock. that says a LOT right there.

In the gasser dept, I cant offer much information. Cummins is KING.

OK, sounds good, it's my first truck so it seems like it would be a nice truck from what my mom saw of it and what the guy told me. One of my lawns is over near the guy works so ill be going over there tomarrow to check it out, I can't wait. Ill be taking out a loan from my parents for it as i have too many expenses to save up all of the money i need for title, insurance, etc. by the time ill have my lisense. A very good friend of mine is a transmission specialist and can fix any tranny problem known (except one instance, long story!!) Anyway, im very excited to go check this out tomarrow!! thanks for all of the great posts answering my question very clearly! thanks!

make sure you carfax it. Before I bought my new expedition eddie bauer I carfaxed a bunch and found out how many owners had them and any accidents. Saved me from buying one that was a good price but in a wreck. its worth the 40 dollars for the unlimited.

I have a 99 2500 4x4. It has a V10 with auto. It pulls my trailers with no problems. Gas milage sucks, 8 mph pulling a loaded trailer and 15 mph highway empty. I have had no trouble with the auto transmission. It gets serviced per maintenance manual. The rear brakes need to be adjusted at every oil change. The auto adjusters don't work to well. Other than that it is a great truck.

The 5.9s are gas hogs but they put out a lot of power! The auto trannys are not great at all. The cu,,ims are legendary!!

Emercape - We have a 95 cummins, what mods can be easily done to it?
Any info would be appreciated.

off the top of my head I don't know. But my friend has a pre 98.5 Dodge 2500 Cummins, 6 speed twin turbos, jake brake, custom intake and complete Banks exhaust, intake, and intercooler. He told me when I was looking for another truck that I should get a pre 1998.5 becuase the mods would be much easier. I will give him a call and see exactly the bods and cost of each but the truck he built is unbelievable. The thing sounds like a tri-axle cumming up our hill, and has the power of it. His brother has a 1985 F350 6.9 Diesel, set up just like the other brother's dodge.

MCW.. One thing to consider when buying the truck for your business, you can always change springs to increase your gvwr. Bulking up your truck isn't very expensive and it will help decrease the life of your truck for heavy hauling. Also look into a good dump insert and if needed air bags on the rear axle.. again another cheap option ....Air bags - $300 adjustable on board air and a dump insert $2,200 to $5,000 depending on who you go with.
