Cummins VS Duramax

I am debating between a 2008-2009 duramax and a 2010-2012 Cummins, both crew cabs short box in 2500. Let me hear what you think problems likes dislike about the two.

Cummins.  Granted the chassis and drive train isn't as good as the chevy, fixing the chassis and drive train is a hell of alot cheaper than fixing the engine.  And a cummins you can actually work on if your somewhat mechanical.  It's a million mile motor.

Cummins.

Unless your planning on getting in drag races with Powerstrokes or Duramax's and cant stand loosing. Because you will. And when that happens you can feel good about your engine longevity and fuel economy.

All 2009's had the 6.7 liter.

In 2007 both engines were offered. Later than that it's been 6.7.

basically i am looking at an 09 chevy ltz with 67k dmax for $30k and 2011 cummins slt crew with 40k for $30k, the chevy is loaded to the hilt and a nice clean truck the dodge lacks options but is still a nice truck, to me it is about a toss up but i figured the FBO crowd is running some of these trucks and could throw their 2 pennies in

Between my son and I we've had fords and chevy's.  got rid of both because the cost to repair all the problems with the engines was absurd.  My son's duramax blew head gaskets and had to replace all the injectors.  then a year later had another injector go completely out and was told three more were sketchy.  that was a damn year later.  those remanned injectors are obviously junk.  ridiculous when you spend 50k for a truck.

Pulling occasional horse trailer with 2 to 6 horses otherwise 28ft camper and 20 ft boat. My 6.2 half ton with air bags pulled them just fine but i just need the extra room of a crew cab now and with the new 2014 chevy the only way you can get the 6ft 6in box and a 6.2 in a crew cab is in an ltz....for that money i will buy a diesel...I still haven't crossed off the idea of just getting a brand new diesel ford, chevy, or dodge, these two prementioned  trucks just seemed like good deals.

well the conclusion I've came to over the past half eight years is that to own a diesel you'd need your head examined to ever own one outside of warranty.  the price of parts alone is so far past the absurd level it's ridiculous.  then $110 an hr. shop rate, who the hell could afford to own one outside of warranty.  Or should I say who's dumb enough to own one outside of warranty.  Unless of course you've already spent 10k making it bullet proof.  But then the drive line doesn't hold up to the power they're making these things put out.

 My dad has an 08 duramax he pulls fully loaded stock trailers all the time he has just over 100k and has never had a prob. I have an 11 Cummins for my work truck I pull a heavy goose neck trailer allot but mostly just sales I have 60k miles and I've had to replace tie rod ends that was a recall and I've replaced shocks twice and have had 2 exhaust problems and you can't go threw any water puddles cause it soaks the air filter and puts it in limp mode and that sucks

The scarry thing about buying a used diesel is most of the time you don't know what it was used for and how it was abused, regardless how much smoke somebody blows at ya. Going brand new is expensive nowadays but it gives a guy peace of mind with a warranty. If you end up looking into fords, stay away from anything thats older then 2011. Unless of course you get yourself a good ole fashioned powerstroke of course. The 6.0s were junk 08-10 came the 6.4 which was better but trust me they've had their fair share of problems too, kind of hit or miss with those, but when they hit, its like a 6-8k hit ouch.

 I have an 07 Duramax and couldn't be happier.  That being said, I think the cummins is a good motor now.  I personally just love the feel of the Chevy and the Allison transmission is amazing.

I wasn't referencing that ford tranny, sorry if you thought that.  the 6.0 tranny is actually a very stout unit.  I know several people in Williston alone that have roasted their allisons, sent them in to be built up and have roasted those also.  But they have them making alot of horsepower over stock.  And they drive like, well, rednecks to say the least.  Same with the dodges.  Two of the tool pushers on our rigs have heavily built up dodge cummins trucks and have had to junk the stock tranny's and had to buy atf tranny's.  And they both had the stock tranny's built up after tearing them up.  One thing about the dodge tranny's is the cases are weak as hell.  You have a u joint go out you need to fix it immediately or you'll crack the tranny cases.  very common issue.

company I worked for a few years ago roasted a 6.4 at the 15k mile mark.  dropped a valve.  not very impressed.  and don't ever air bound the fuel system or you'll be an extremely pissed off hombre.

Air bound the fuel system?  What the heck is that?

I have a 2009 6.4L powerstroke.  73,000 and everything is going well so far.  Couple of hiccups, alternator bracket, front seal.  So now that these engines have been around a spell, what are their weak points?

p.s.  put a cummins in either a Ford or Chevy vehicle and you'd have something.  A "million mile engine" engine ain't worth squat if the remainder doesn't tag along for the ride.

Might as well go to Aberdeen and get yourself a brand new dodge with a full warranty.

I have a 02 Duramax just at 199,000 miles.  I have not had any issues yet.  Besides the general maint. like ball joints and shocks.  Those have been replaced only once.  I truely love the Allison Transmission.  My father has 3 dodge cummins trucks.  A 94 with 500,000 miles. a 04 with 200,000 miles that has been a lemon, now he has a 14 with no miles so cannot say how that one is.  But he is a dodge guy for diesel's.  Now, I think it would be great to have hooked up on of the great ford 7.3's with an allison tranny.  I think you would have one hell of a truck.  I do know this, and I do alot of reading on diesel forums.  No matter which one you have, it seems that 90 percent of the people that have had problems seem to be chipping them up.  I don't care if someone says i have had no problems with mine.  Just read the forums.  Once you start tinkering, after awhile you will have some kind of problem.  Best to just keep it stock.  You can still pull the ass out of anything!

I put a cummins in a ford already lol.  you won't wear the ford chassis out very quickly.  the others, not so much.  have you personally changed the fuel filter in your 6.4?  or has the shop always done it?

you are exactly right.  although the 6.0 has so many issues not related to chipping it's retarded.  the problem with chipping is these engines weren't designed to see that much boost.  that's why you stretch head bolts and take out head gaskets.

 If I had to use the truck as a daily driver and was doing a lot of in town or short trips, I'd have a hard time buying anything newer than an '06 because with the choked down exhaust a guy really needs to get them up to operating temp pretty much every time you start/run them.  When it's say 10F ambient or colder, my truck takes ~20min of DRIVING to come up to temp, sitting and idling will barely move the needle.  Seems like when a guy doesn't get things up to temp often, that's when the nagging problems start to occur.  I don't really think that anything from '07 on from Ford, Chevy, or Dodge perform well/last if they're doing a lot of sub-operating temp driving.

This moment is a paradox, it's the oldest you've ever been as well as the youngest you'll ever be.

If I let my 07 duramax idle when its cold, it doesn't come up much. I just set it so it idles up and that pretty much solves it. I wouldnt drive any truck in the winter without allowing it to warm up. Even in the summer, I won't pull anything much above idle until it hits 210

07-08 GM diesels had mpg's issues 13-15mpg) due to the new  emission regs that kicked in 2007,since then GM is back in the saddle with better milage and more power,in 2011 GM redisgned the entire chassis,bigger and beefy'er but ya need to deal with the "def" fluid.

Really can't beat the GM powertrain,engine is quiet,does'nt smell,plenty of power and the tranny is bullet proof.

I guess I've been pleased with my mileage. 07 and I'm getting 16-19 hwy not pulling driving 70-75 mph. Pulling really depends on load. Worst I've seen is 9 mpg but usually in the 11-14 mpg area. Maybe not amazing, but it sure is nice to pull with.

I've gotten to the point in life where I have better stuff to do than the mundane maintenance on my vehicles.  So the Ford dealership has always done it for me.  That, and I like the idea of them having all my maintenance records in their computer system on the outside chance a warranty issue comes up.

 My 09 chevy half ton hauls the grocerys well. Rides like a cadillac I'll give it that. At least its good for something. I like the 14's but don't think I'll be going half ton this time.

that's what I figured. you need to get with them on the method to purge the fuel system of air so if you ever have to change a fuel filter in an emergency you'll know how to do it.  If you air bound it you'll have a hell of a headache on your hands.  they are not fun to de-bound.

Make sure you give them time to cool down before shutting them off or you will cook the oil in the Turbo.  Too many get where they are going and just shut them off.
