Cummins ISX broken valve in #6

Although it sounds like the original failure might have been 10/17 and the coach originally went to the diesel shop in 1/18

Still waiting

As I understand it Cat got out of the on road market so Cummins is the sole survivor. If the ISX has a problem what is left in a newer MH?

Thanks for the update "spuds", and.....that's a good question "nothermark", there's no other choice really with new coaches. Mr. D pointed out the differences between the new post 2014 engines and pre 2014. Yet, it seems some obviously have the issue, so I'm not yet convinced the disastrous problem is dead.
I'd really like to know the current percentage of failures per all post 2014 SOHC ISX engines built.

I have an 07 HR Navigator with a 2006 ISX 525hp engine. I’ve read all the horror stories and have had no problems. I really believe the problems are mostly associated with the engines that have the DPF filter. It’s equivalent to sticking a potato in the exhaust and I think it is the extra back pressure combined with the EGR that creates most of these problems. I have the Ugly fix on mine to fool the EGR into thinking I’m over 7,000 ft altitude so it stays closed all the time. I have a friend that has an 04 ISX in one of his farm trucks and has over 400,000 miles on it with no issues like discussed here. Maybe we are just lucky, but I have an automotive background and used to race so I am really pro maintenance and treat this behemoth with lots of respect in regards to warming up and cooling it down as well. These are all MY opinions and not looking to start wars with those having troubles with theirs. I would gladly purchase a pre DPF coach with the ISX in it again.

Hello everybody,we have asked to hear from any isx owners who had the common #6 intake valve failure and the head etc rebuilt after sept 2014(allowing plenty of time for the more robust valve to have been used)....so far we have not heard from anybody,nor can we find any cases online except possibly mr.d who thinks he may be around the corner from one such failure(his initial failure was back in 2010 which was prior to Cummins developing the new valve)...i would disqualify that case based on several things I have read about his circumstances...or perhaps an isolated incident...or a screwup when the previous repair was made.....I would certainly call into question the entire maintenance history of his coach since he stated that upon acquiring the coach with approx 45000 miles,he discovered that the tranny had NEVER been serviced,not even the filters required at 5,000 miles,this after 6 or 7 years.....or when he discovered in his 13 pages of repair paperwork that the mechanic had requested new rockers...because his were worn out...with that request”DENIED”......obviously if a rebuild is done that leaves worn out parts in place,that can affect the future performance of that engine.....finally,mr d has stated that because of health issues,there was a period of time the coach wasn’t operated......and from what seems to be common knowledge at this point,moisture/acid sitting in the valve train for extended periods of time,rather than being eliminated by operating temperatures can be problematic.....in short,if there is an isolated incident,or a case with extenuating circumstances like mr d’s......that is one thing....if however rebuilds that used the more robust valve are failing that is quite another......I think anybody reading online would conclude the original valves in the cm871 had an unacceptable fail rate in r.v. Applications but to date I have found not one failure of the more robust valve that Cummins developed to fix this problem....PLEASE RESPOND IF YOU HAVE FIRST HAND KNOWLEDGE OF ANY SUCH FAILURE.....and mr d.....I know you are just trying to help others,and ticked off about your mechanical failures but it’s important to present the entire set of circumstances surrounding your issue......I have traveled 40,000 miles since my April 2015 rebuild trouble free.....and so far in questioning several Cummins shops,I have not been advised yet that doing anything is advisable as a preventative measure with me asking for nothing...willing to pay.......of course if there are failures of the new valve....that is relevant....AND THAT IS THE REASON FOR TRYING TO DETERMINE IF ANY NEW VALVE REBUILDS HAVE FAILED......we just need the facts

Newer Allison 3000 and 4000 trans do not require a filter change at 5,000 miles. Mine was new enough that it wasn't required. It was however due for a filter change on time alone
The second rebuild was in March 2015 and supposidly did get the new valves but I can't confirm it.
I also have The Ugly Fix, can't notice any difference except it takes about 30 miles at highway speeds for the engine to warm up and give me above 5 mpg.

I had the failure earlier this year. I do have a service contract and they covered all related costs. Through the process that took 6 weeks I did ask for a few items be updated like the EGR cooler. So far the temp in the rear bath and the overall engine temps are cooler.

It coat 25k for all repairs which included new #6 cylinder piston, liner and injector. A new turbo, EGR cooler and full service of the cooling fan. I also had to have them cut the rear structure out to get the head out and I modified it so now it bolts in and out. They changed the oil twice, did extensive testing and inspections, new air filter etc etc etc. So I think the costs to update a head is lower by 5k but each Coach is different.

The assumption that a 500hp is different than a 650 is wrong except for the power. All internal components are the same, one limitation is the transmission. A 650hp is tuned to limit to 1,950 ft lbs of torque due to the Alison 4000 trans, its max torque is 2,000 ft lbs.

Any CM871 with a head rebuilt after 9/2016 is 100% updated. Any CM2250 with an engine / head after 4/2015 has the update.

I do believe it was a rush to market by Cummins and they didn't have any idea of the issue. Some may think they did and didn't care but the cost for updated components vs the original would have been the same based on volume. So I think it was a screw up on their part but they did fix it with the best materials available.

I would recommend that anyone looking at an ISX with a suspect head deduct 20k from the price. I also think people with the updated head either updated by them or a newer engine should ask for more.

In the end anyone with an ISX loves them. I can pull a compact car off the line when I am not towing, I can climb any hill at 65 mph and I get 1/2 mpg less than a our last smaller coach with a C7.

Yes there is an issue, yes there is a fix. Complaining like children will not fix it.

Mr D is vocal and rightly so, his failed just after he bought it. I can say that Mr D only points out facts and doesnt say the ISX is crap. Guess he is like Walter Cronkite, just the facts you decide....

I know of another CC that failed at 12,000 miles and about 1,000 miles after purchase. His CC # is 6998 and mine is 6999. His did get the latest parts including the carbon scraping liners and special matching pistons

I had service by Cummins in SC. The lift pump gasket leaked and warranty from Cummins 100% covered it. The tech told me all new pistons and rings are the carbon scraper type. Not sure if that will be an issue for all but when open it may be worth looking into.

The one item I follow with you Mr D is the turbo issues you have had. I haven't heard of many failures below 200k miles. Do you think it has something to do with the tubes used on your Coach?

I'm a Class 1 commercial fuel truck driver and many of my friends drive Big Rigs as well. LOTS of anecdotal stories about ISX failures but as mentioned here most are related to turning up the power excessively. I don't understand the need for 650 HP in a coach - I drive a Super-B Fuel Tanker weighing 140,000 lbs loaded around the Lower Mainland and Fraser Valley of British Columbia Canada with 505 HP and 1950 ft-lbs.

500 - 550 HP is pretty much the accepted ceiling for nearly all 80-140k lb GVW trucks and many carriers are going to 435 HP tunes for their 80-105k lb GVW rigs.

I can pull an extended grade of 8% at 45 kmh/h (~30 MPH) loaded with 505 HP in a gutless and lacklustre PACCAR 13 litre I6.

A coach should be just fine at 500 HP.

Torque and HP are independent in large commercial diesels - you can get 1650 to 1850 (with a few outliers at 2050) ft-lbs on engines rated from 400 - 550 HP. In other words, select the torque and HP independently for your needs.

You should already have TranSynd in it.

5000 mile filter change is no longer required as they use a new filter type.
Quote:
New high-capacity filters were released into production beginning with: 6510670912 (3000) 6610205144 (4000) 7110001551 (H 40/50 EP) 6520067342 (3000) 6620002521(4000)

3000/4000 Product Families Transmissions Elimination of Initial Filter Change Requirement and Kit:

Transmissions equipped with Allison high-capacity filters do not require an initial main filter change at 5000 miles/8000 km/200 hours. However, serial numbers prior to those numbers listed above, Allison Transmission requires the initial filter change interval. An initial main filter kit P/N 29540495 (2 inch) or kit P/N 29540496 (4 inch) contains only one Gold series filter and all necessary seals and gaskets to perform the first 5000 mile/8000 km/200 hour main filter change. These kits have been
completely cancelled. Once stock has been depleted, it will be necessary to order the high-capacity filter from the Allison Parts Distribution Center.
Both our DSDP's had 2" sumps.

Easy to change the filters, 6 bolts on each filter. Filter kit comes with full instructions and gaskets. I've done it several times on the 3000MH and now our 4000MH. Be sure you have a torque wrench and use it.

Go here and enter your transmission serial number for full info, most of it useless to an owner.

Here's a link to ST 1099 that covers what you need. http://www.allisontransmission.com/d...s.pdf?sfvrsn=2

SEE BELOW MR D WROTE

“After I got the Magna I figured I better change the filters and replace the lost fluid. I found that my trans # was before the new filter change and the old filters said OEM on them. By then it had about 47,000 miles on it an no service had ever been done, not even the required 5,000 mile filter change. That's why I prefer to do my own service”!

Thanks for the good news.

Using wild guess numbers in the Allison calculator it comes out to 300K for fluid and 75K for filters. I am assuming since the 5K filter change reference in my owners manual and the 1099 form is outdated because the Allison calculator is the most up to date and does not mention it.

What I posted regarding the serial #'s for the new filter came from the 1099 link I posted, they should be the same.

info for those 3000 series owners -

the old filter kit #29548987 has been upgraded to a new #29558117. when you order the filter kit, make sure tell the seller to ship the latter only or reject the shipment. many of the allison dealers don't have the new one in stock. knowingly those are different, they might ship the old one to you, because they want to get rid of the old one before get the new one in.

while i was shopping mine i ran into this.

Not sure about which calculator you are referencing but filter changes have both a mileage and a time factor. After considerable research and conversation, I have settled on filter changes every three years [approx. 36k miles] and fluid changes every 6 years [note: you will lose a couple qrts to a gallon of fluid during filter change]. Also use periodic fluid analysis to monitor potential contamination issues during the 6-year fluid time period......

19 qts when draining and refill. Do not flush. All Allison's shipped from Freightliner since about 2004 have Trans Synd from the factory. The newer filters do not require replacement at 5K mi any more.
If you're like most folks and put about 7-8k mi/yr on the coach, what I do for mine is change oil and filter every 5 years at the same time. If you are concerned, have it tested.

Measure the thickness of the bottom section of the tranny. 4 inch sump measure about 3 inches. 2 inch sump measures about 1 1/2 inches.

Allison high capacity filter part numbers
All,

Just spoke with the Allison Aftermarket Parts Manager. Below are the latest "High Capacity" filter replacement kit part numbers. These part numbers should be used for servicing all MH3000 or MH4000 Series transmissions. Please pass this information along to whomever has the "need to know".

Note: These part numbers are directly from Allison so you can trust that they are correct.

Thanks !!!

Thanks for the link to check by SN. Looks like my 4000 has a 4" sump. Does anybody know how much fluid is lost, changing filters?

Anybody have any knowledge of how much oil is lost changing filters? Does it increase from a 2" to 4" sump, 3000 or 4000? I am buying filters today and want to pick up some Transynd to replace it. From the few comments I've read, I was thinking a couple gallons would be enough?

After I got the Magna I figured I better change the filters and replace the lost fluid. I found that my trans # was before the new filter change and the old filters said OEM on them. By then it had about 47,000 miles on it an no service had ever been done, not even the required 5,000 mile filter change. That's why I prefer to do my own service”!
