Engine/Transmission (1998.5 - 2002) Looking for Exhaust Brake Permission Documentation from DC or Cummins

[CoreyPerez]

Folks,



Here is the issue. I've limped my 02 into a local dealership because of smoke, no power and a huge ticking noise under the hood (Best described as Monkeys with Sledgehammers). Well, the dealership determined that it wasn't the valves (As I thought it was) but instead the #2 Cylinder grenaded and the noise was piston slap.



Well the service tech told me that its just a fluke failure and nothing I did caused it. Most failures like this happen in the rear of the engine, not the front and they were waiting for the service rep (out of town today) to come by and authorize either a Short or Long Block. When I attempted to talk to service about a Rental Car (Part of my Service Agreement) the lady told me that they were waiting for authorization from DC because of the modifications I've made to the engine (IE: Exhaust Brake). When I explained that Cummins authorized the use of a Exhaust Brake, she told me this was a DC Warranty issue, Not a Cummins, and it was up to DC to make the determination, and the brake was considered a aftermarket modification that could/may void my warranty. SO, I'm looking for any valid website that stated (Which I don't remember WERE I seen this posted/printed) that Cummins gave the go-ahead for braking our trucks.



I may find this information in my searches, but so far haven’t found anything. I figure I may as well get my documentation in line in case this gets ugly…



Thanks in advance!!!

How about a Mopar exhaust brake. Would that be proof enough? Who knows?

Hope this helps.

have i not read somewhere on tdr that d/c does not approve an exhaust brake on 98. 5 to 2002. have they even approved one for the 03&04?

 

[klenger]

Dodge and Cummins has approved of exhaust brakes on all trucks with manual transmissions. If I remember correctly, the 12 valve trucks need to have the valve springs replaced to handle the increased back pressure.



Corey: What brand was the brake?

 

[Pawpaw]

His sig says "BD Exhaust Brake".

 

[Steve St.Laurent]

Look in your owners manual and you will find that an exhaust brake is recommended by DC when towing over a certain weight. That should be enough.

 

[Sticks]

Unless it was Mopar, they will still cry foul.



You will need to get the performance specs on the Mopar/Jacobs and your BD. This should include time from throttle off to activation and backpressure both along the RPM curve, and peak. So long as your BD does not create higher backpressure than the Mopar, you should be able to get them to let it go. Otherwise you will have to prove that the BD is not the cause of the failure.



I'd say get your truck out of there and find another dealer, but the note has already been made in your DC file.

Thanks for all the input guys!



I've got a little bit of research to do, and I hope it all works out. Does anybody know how much ground I have to stand on if/when the replacement block is ordered if I can request a "Non-56 Series Block"? And is Cummins using those as a Re-man?

Corey

I hope you mean a "Non 53 Series Block"

 

[CoreyPerez]

YEAAAAAAA Thats what I ment...

 

[CoreyPerez]

Just an Update, Talked with the district rep, he said he can't see anything that looks like it would void the warr (Exhaust Brake, BHAF, etc... ) so they are going to tear into it, and check the internals. They need to check for damage that may have came from inproper oil filters. Which currently, there is a K&N Oil Filter (I was in a pinch!!!)



Corey

 

[Sticks]

Now the anxiety starts all over.



I hope that it was a legitimate failure on Cummins, and not a filter issue. Probably end up being a cooling jet popped out.

 

[CoreyPerez]

Sticks,



What is a cooling jet, and what exactly would it do? Is it a oil jet that sprays oil on a particular part of the motor?

 

[lmills]

a cooling jet sprays oil onto the bottom side of the piston to help cool it

 

[Thomas]

TSB 09-004-01 is the TSB that mentions clogged piston cooling nozzles. It seems to me that it would be to your advantage to have all evidence of the failure documented and preserved if it turns out to be a filter problem.



Good luck!

 

[Andy Redmond]

If so (clogged cooling nozzle), K&N's Liability policy is about to me tagged! I would ask to see and photograph the "FOD" if this is the prognosis. Sounds like the dealer's treating you ok. . Good luck and hope its on the road again soon.

If it's not to late, you might want to consider grabbing an oil sample.



Good Luck,

Hey folks,



here is the news.



The truck has been in the dealership for over 1. 5 weeks now, they determined Friday afternoon that the failure was the #2 Wrist Pin bearing failed, causing the rod to slide back and forth with in the piston, which translated into a hard time on the crank. DC has determined this will be covered under the 5yr. 70k warr. so I'm VERY happy about that. We are looking at: New Piston, Bearings, numerous seals and other misc. parts. Ive got some pictures I"ll try and get loaded up shortly, but I'll tell ya what, that motor is HUGE! I couldn't believe how long that dang thing is, and I got to play with the pistion that has all the damagae, and inspect the main bearing that is chewed up from trying to keep the piston rod in line (Huge gashes and garbage in the bearings).



Thanks for all the feed back, I have learned a bunch of very good lessons from this endevor.



I purchased a extended warranty just to find out its junk, its not the Dodge warr, but one the dealership sold me, and even though the truck will be down for nearly 2-3 weeks, I may only be able to get a rental vehicle for 2 days. The company is very hard to get ahold of because of all the recordings and now a new set of concerns sets in. LIke will any other damage show up in a year or so down the road because of the added stress the engine components were placed under during this, and what about oil leaks and... Ya, could go on and on.



Thanks again all! Looks like I don't have to worry about buying a new motor any time soon!

Glad you are getting taken care of.
