I'm looking at a 2004 Chevy with a Duramax/auto that has 146,000
miles on it. I was wondering if that is considered high miles for this
vehicle and what if anything in particular I should look at with regards
I disagree. While they tend to last longer they aree not semi motors
as many seem to equate them too. 146,000 miles in 3 years is a lot of
driving. Engine is out of warranty and they are very expensive to
repair if need be. I would say walk away from this one fast unless
maybe it is dirt cheap. As a 2004 they are going to want a bit of
money and it is safe to say that more than 1/2 service life of truck
is gone menaing it is going to need engine, tranny and chassis work
sometime in future. The question is when. Also the front ball joints
do not last long in Dmax trucks because of weight of engine and unless
they have been replaced recently, they will need replacing now. A gas
truck with 150K miles has a lot less to go wrong with it and is a
safer by because it is simpler and cheaper to fix too. his is not a
gas vs diesel pitch here but buyer beware on a high mileage diesel
with no firm history of usage and maintainace and no warranty. Last I
heard the injectors in that engine were 400 bucks a piece. GM has had
some issues with injectors through 2004 models. Not as bad as Ford's
6.0 but issues none the same. If you really want a diesel and are new
to this find a lower mileage mill with some warranty on engine because
you do not want to cut your teeth on this one.
Why does it not suprise me (or anyone else) that you would disagree
with something about a deisel engine. It is "public" knowledge that
you have great disdain for them as you feel they are nasty dirty and
If 146k on a d is a lot, what is 200k on a gasser that has never need
nor had a rebuild and still runs like it did the day it was bought?
Duramax. While 146,000 miles isn't a lot on that drive train it is high
mileage for an '04. Check Kelly Blue Book and NADA as I believe both of
them consider mileage in determining the value of the vehicle. Both of
those sources showed a sizeable hit in the value of my '01 due to 'high
mileage'. There was nothing wrong with my '01, it was just 'high mileage.'
In my opinion, a Duramax with 146,000 miles, unlike a gasser of that
mileage, still has lots of miles to go before it is worn out. Just don't
pay the same amount as you would for an '04 with 50,000 miles.
I still disagree because properly maintained, 200K plus is easy to do
on a gasser. It is all in how well you maintain it. 150K in 3 years is
a lot for a gas or dieisel moter in a LD truck but the difference is
"IF' the Dmax needs repairs out of warranty you will cry over bill and
I would not get a high MPG one of unknow maintaince quality with no
warranty. Get one with some engine warranty so you are not left out in
cold with a used one.
The problem is mine is driven by logic and yours ego like some others
and you will not pay his repair bills if you are wrong and it is a
expensive risk. There simple is a lot to go wrong with the controls on
that engine and none of them are cheap to fix out of warranty and I
factor that in my answers while you do not. If it had 80 or 90K on it
is would still have some engine warranty at least.
Why does it not surprize me as to how blind you are to simple logic.
This is no surprize for a troll though. It has nothing to do with my
personal preferances. I just advise people of possible problem for bad
advise from troll like you telling them that it is like a semi truck
motor and it will last 300 or more K miles with ease but it is not a
semi motor and its very techology makes it more trouble prone as it
ages and more expensive to fix as there is nothing cheap about
repairing one of those out of warranty.
Guess what Troll, I have run many gassers past 200K plus and they ran
fine. As a amtter of fact I have never worn one out to require a
rebuilt on anything I have bought new in over 30 years. I have a old
89 4x4 burb that I bought new that has 181K on it and it runs like new
and uses no oil and idles smooth and gets great MPG for its type. That
engine easily has another 100K or more in it. It still. has great oil
pressure and quiet when it idles. These days it is not driven daily
and at times it sits a lot in winter to keep it out of salt but I can
go out after it has set for several weeks when it is below zero and it
will start right now without a fuss if I need it. If it had been a
diesel that old it would have had a lot of problems by now. There was
a time when diesel were low tech and pretty simply and not much to go
wrong with them but that is not the case now because there is a lot
more to go wrong with its controls. Also if you put a 10 or 12 quart
oil pan on a gass motor with a good cooling system and HD oil cooler
it will last a long tiime even when being worked very hard. The
problem is while a diesel comes with these things by default, it
cannot survive without them while a gas motor can. If diesels in LD
trucks last longer it is because their owner maintain them better but
they have to because failure to do so will shorten their life a lot.
But a this is too much logic for a Troll so knock yourself out with
some other pointless dribble.
I'm a troll, man you are funny! Don't you have an answer to post in
the Dodge group about the knock sensor you say exists on a Dodge V-10?
I don't give bad advice, that is you that does so. Remember your
advice to a woman in the Dodge group that had a bad speed sensor? If
not I'll remind you, you told her to trade it in for a $50.00 part.
As to it being a "semi-truck" motor, I never state that or anything to
that affect. HOWEVER, being that it is a diesel, ever with 146k it
has MUCH more life in it than you want the OP to believe. Even if it
is only 3 years old, if it has not been modified and regularly
maintained, there should be little wrong with it, regardless of the
milage. I am quite sure the OP knows it is out of warranty, and I am
quite sure the OP is aware of the other possible issues with the
vehicle, else he would not be looking at buying it.
So, 200k on a gasser is fine, but becasue of your hatred of diesels
146k is too much? A diesel is made to out last a gasser, so would you
care to explain your logic here?
> But a this is too much logic for a Troll so knock yourself out with
No logic is not too much for me to understand, it is you who is to
much. But hey, no worries, people much more knowledgable in diesel
will chime in and will continue to prove you wrong.
I well remeber and other agreed that older Dodes can sometimes milk
your money away as I did not have only veiw like that.
No, how much life it has left depends on how it was maintained more
than engine type but trolls like you do not understand that because it
is like because it is a diesel is is guarenteed to last a lot longers
when it is not. This is not a old Ford PS or CTD with a low tech
mechanical pump that can run 1000's of hours. Nor do you even consider
what low sulpher fuel and its change in lubrication properties will
have on that engines pump and injection system because GM is tight
lipped about it. You are playing a experament and he is the test
subject for your to feed your ego because I do not think the OP
understands how expensive it is to have it worked on out of warranty.
Maybe you like having a engine with 400 buck a pop injectors and no
warranty, I do not. They had trouble with them and changed there
design again in 05 because of this. They did extend warranty on some
2002 thru 2004 models injectors to 200K but only if problem surfaced
in first 100K and you complained about it. You know I have a freind
that bought a Dmax new in 05 and he was all hyped up about it (his
first diesel) but the honeymoon is over and he wants to get rid of it
and has no more desire for another one. He wishes he had held out for
a 8.1 instead. I error to caution while you as a true troll errors to
Gee, thats funny, I have made the statement TWICE about checking
modification and maintainence records. To ensure that proper
servicing was performed. Here you sit saying the exact thing that I
had mentioned, but if it is from anyone but you, they are wrong.
News flash for you, because it is a diesel, when properly maintained
it IS guarenteed to last longer! This is not opinion, this is FACT,
something you have no concept of understanding. Why the hell do you
think that there is a longer warranty period on a diesel then a
gasser? Simple, because they last longer and when properly maintained
are less likely to encouter a problem and will/may take longer to do
so IF/WHEN they do.
This is not a old Ford PS or CTD with a low tech
You have a friend? This is highly doubtfull
You Snotroll are the one with the Ego problem not I. If you insist
you don't care to explain why you are so much a coward that you will
not answer the questions that have been repeatedly asked to answer in
the Dodge group. Wait, I'll answer that for you, because you were
wrong, you were caught, you were called on it and now you tuck tail
and run instead of stepping up and admitting to it.
If the above is any indication of your knowledge of Duramax, their injectors
and their warranty, then there is a great deal you know that simply isn't
The injector warranty on my '01 was extended to 200,000 miles. It made no
difference if the problem occurred at 99,000 miles or 199,000 miles, it was
covered. The problem with injectors through, I believe, the '04s was a
single bad batch of steel used by Bosch(?) to make injectors. If you had
injector made from that batch of steel they were going to fail. The
warranty through GM was actually covered by Bosch(?) or perhaps even went
back to the steel manufacturer.
While I agree that 146k is not too much on a Duramax, the fact that someone
drove this vehicle so much in 3 (+/-) years, you need to consider potential
repairs as everything else wears out. Have you priced a tranny, rear diff,
exhaust etc.? While a good strong engine is very important, I would be
looking at the entire package....A diesel nice to have (my next Silverado
will be a diesel), but what's it worth when you're constantly
fixing/repairing the rest of the truck....
My 2 coppers for what they're worth...Good Luck
