Million Mile Engine

changingtime · **Posted:** Fri Jun 25, 2010 8:59 pm

I read that the VM engine in the CRD is supposed to go to million miles. Any thoughts on longevity of the engine?

That would mean that I would need to invest into 10 timing belts and other Misc parts.

1,000,000 Miles Divided by 24,000 miles a year,would equal 41.66 years of ownership.

Heh, I drive about 8k miles a year right now... If that stayed the same, it would take me 125 years to reach 1 million miles. I'm pretty sure the body will fall apart before the engine does.

More like your body will fall apart before the Jeep does.

Am I the only one here that typically does 35-40k miles per year? BTW, just about all my family drives that much. We killed a 3/36 on a brand new 94 Town and Country minivan in 14 months.

Also (b/c of a bad design) killed 3 transmissions in it at 40, 80, and 120k. It is over 225k now, with the trans from 120. All it needed was an aux cooler.

geordi, as a grad student, I live too close to everything I could possibly need to drive very often... School is four miles away, the grocery store and Walgreens are across the street, Napa/Ace is down the road, etc., etc., so I bike almost everywhere. Before I began working for some folks up in Flagstaff, I drove <100 miles/month :shock:

I'm sure that once I get into the "real world" things will change. :dead:

Well, I will say that in the last week or so I haven't been driving much at all - B/c I am now among the ranks of the recently-graduated... And now unemployed. Ah, that job sucked anyway.

Where I am here in Sc, just over the border from Savannah, everything is 15 miles away. Publix (supermarket for the non-Florida people that have been deprived of their awesomeness) is in one direction, Savannah downtown is 10 miles the other way... And all the retail I might want is on the south side of Savannah, so 20 miles usually.

Add to the distance that it has been 100* and 105% humidity the last week or so.... And I don't even want to go outside to check the mailbox.

Does that include rebuilds?

Don't worry, it'll start cooling down....around mid November!! :-)r

Gonna' have to call BS on this one.

The legendary Cummins ISB engine is a "medium duty" engine. I.E., it's a step above all the other diesels in cars and trucks in this country. And even the Cummins is only rated for 300,000 miles before overhaul.

So there is no way the VM will go 1,000,000 before blowing up. There may be one or two that make it there...but the majority will not.

There might be some confusion here about overhaul ratings. The Cummins ISB is rated to 350Kmiles at a B50 duty level in a medium duty application (i.e School buses, Dump trucks, etc). B50 in this case means that 50% (or the average) of vehicles will need the head or oil pan pulled by 350k miles. They don't give an estimate for light duty applications but most pickup owners will get far more than that before the head has to come off (assuming that the factory service schedule is adhered to closely). The venerable Mercedes OM617 engine doesn't have a Bx rating but the average rebuild was estimated at 500k miles in average service, and a not insignificant percentage reached 1000000 miles easily.

The VM M 2.8l will be very capable of reaching 1 million miles.

Well then if this engine will reach 1 millon miles and the body can as well then I already bought my "Retirement Car" at age 36!!!!

When it gets there, let us know :roll:

The Dodge Cummins is a medium duty engine in a light duty vehicle. There are a few million mile plus Cummins out there. I heard of one 1.2 or 1.3 million miler without a rebuild (but it was toast). Every case of a 1 million mile Dodge I am aware of was without overhaul. However, the only engines out there with this kind of mileage are used commercially and driven with heavy loads most of the time on the highway. So basically the Cummins in the Dodge has no known engine life under usual conditions. As stated the 350K rebuild is for a much higher duty cycle than the truck applications. Will the light duty VM do a million? I doubt it. But 500K+, sure. Too bad the libby suffers the same problem as the Dodge; a million mile motor in a 100k mile truck.

Ain't that the truth. In the fullness of time, I might pop for some body work on the CRD. Winter driving here can create a rust bucket long before 100K.

They have these things now, a fairly new invention to prevent vehicle degradation due to winter road coatings... They are called car washes. Just sayin'. :goink:

My CRD spent the winter in snow and brine-covered roads... And got washed once per week at a minimum, or after every slush bath (after it snowed). Heated car wash at a gas station, with undercarriage spray - $5. :pepper:

I don't know about any Chrysler product having non-drivetrain parts that are worth keeping around for more than 100k. The 97 Grand Cherokee now needs a new central message center, the screen suddenly lost half the display about 2 weeks ago. 225k miles, but that is an electronic component. What happened?

You have obviously never lived in the rust belt. Up here the carwashes are shut down sometimes for weeks or months at a time because they can't operate when the temps are below freezing. The roads however will get slushy spots at midday if the temp gets above zero. As the temps warm up in the spring, it doesn't matter how many times a day you wash your car. Five minutes after washing it, it will be covered in salt again until we get the first good rain of the year. The roads stay wet with brine and melting snow banks from the end of February until the end of march. It's just something that you have to experience.

at least Pennsylvania is a little better than the far north is on cars. Here they do shut down car washes in the winter when its below 0°F during the daytime but that normally olny happens a few times each winter when we get blasted with cold air moving down from Canada and it stays a day or so. Yes washing it does help... the less road salt on the vehicle the better but as soon as you drive through slush and snow again the recoating starts again. We do have warmer days when it may rain and wash the stuff off the roads between snowfalls. If you wash your vehicle after the snow is mostly gone or weekly generally your not doing too bad....but corrosion sometimes finds places to start over the years. I try to wash mine atleast every two weeks or more all year and aftter the streets are clear and dry again after winter storms have come

I have seen rust belt cars. I looked a Mazda B2200 truck that was in the paper once with low miles and a seemingly very fair price. the truck was very clean inside and out and indeed had under 50k on it. Then I started the engine which sounded fine except for that it seemed it could have lacked a muffler by the exaust tone. Sure enough after I looked under I saw that only the ends of the muffler were there....everything in the middle was rusted away leaving the last of the muffler and tail pipe hanging on the end. Then the rest of the underside was just all bown every place you could see. So not wanting to pass up a good deal I decided to ask the Lady at the house if I could drive it, she agreed and I took it to Mienike where the husband of a co-worker was and asked him what he thought of the rust and how bad it was... also the cost to repair the exaust. He put it up we looked and I got a price on the full CAT back exasust that was needed and he didnt think it was worth it to buy and keep more than a year or two due to the rust. So I took it back and asked the Lady of the house why she thought the truck rusted like that. She say they had just moved to town from Syrcuse New York, which is upstate NY rust belt.

Up here in the great North, snow + slush + salt = bad-tasting icecone!

Seriously, our best bet to keep rust at bay is to have them treated with anti-rust oil treatment. I for myself have the Libby treated on a yearly basis with the Krown rust proofing stuff. On top of keeping the body & main under parts in good condition, it provides some lubrification to rubber joints and links. Best way IMHO to extend the life of the body, especially with the intent to keep it for a long time...
