motor making a new klattering sound all gauges seem normal power seem ok but scared noise gets louder as it reves up. tried to baby it to the dealer , didn't make it got towed. Mechanic did a quick look ,saw oil down the driver side and then started it and quickly shut it down he said it didn't sound good but had to what til monday to get it in the shop he mentioned that it was possible the bottom end .THIS SUCKS MY TRUCK HAS ONLY 5400 KM .Anyone else had similair problems or noises

tst and downloader not installed

 

So you never installed your boxes??

 

figured i d give the motor time to break a little after watching stock egts run close 1200 under acceleration figured the motor needed to loosen up

 

Any idea of the build date of the engine?
Nat

 

But you ARE confirming that the box was never installed?

 

WHY WOULD IT MATTER IF THE BOX WAS ON IT YOUR WARRANTY IS ONLY AS GOOD AS YOUR DEALER ANYWAY....

 

 

So, was there oil in the engine?

Did you check the oil before you brought it in?

I ask because the tech said there was oil leaking down the driver's side.

Loss of oil pressure is usually the only thing that kills the lower end of these engines.

 

oil pressure was good level also good only thing was the knocking,spoke to a couple of diesel shops there first thought was flex plate I WISH The dealer actually got the truck in today and are now saying that there is a hole in the block by cyl 5 .I gotta see this for myself and take some pics. what da heck could cause the rod to come through the block ??

Spoke to a couple none dealer shops that know cummins motors both made comments in regards earlier problems w/ the 5 & 6 cyl pistons at time of assembly cause of poor lubrication.
Even though i have not install any BOXES yet the peformance guys i ve spoke to tell me heat will be the main issues aslong as the egt s stay in check things are ok and have been in the past
The diesel shops also mentioned that there are lots of trucks with BOXES ,TWIN TURBOS and never heard of this type of problem mostly head gaskets and things of that sort

looking for some help i have a feeling that i will not like the out come as the dealer says that they have called in some engineers to check out this failure the truck only has 5000 kms was due for the first oil change not motor

 

Errr... am I missing something ? Is this your truck ? Is this your signature ?

"05 2500 4x4 CTD 600 48re auto ,crew cab SB laramie 315/70/17 spacers bully dog downloader TST pwr max,5" Bd exhaust 2"leveling springs air box mods pyro,trans. and boost gauges"

Isn't a bully dog downloader a mod ? Any chance that changed the rev limiter ?

You posted this in another post:

"whats up with the high EGTs on the new 05's I can't use my TST higher than 4/3 or my egts go over 1400 real fast. I want to stack with the BDDL when it returns from Bully Dog but the high EGTs already have me worried.
I was able to run the 7/7 setting on my 03 so dually and temps were 1300 under acceleration.
I would like some suggestions on lowering the EGTs with bigger turbo ?which one? water,and or water /meth injection"

So... did you run meth injection ?

A month ago you wrote this:

"I know I know but every once and a while you just have to show some punk that a little rice burner isn't fast and I get a laugh when the get to the next light and won't even look over to acknowledge that they just been smoked by rattlin truck.
Any who my question is for you more experienced racers whats the best way to lanch the truck?? I normally hold the brake down load the drive train then see ya ,but I've heard some guys launch in 4x4 but is that more drag on the truck would be slower ?"

Let me guess. You've been street racing your 05 with stacked boxes ? CTDs don't just throw a rod, unless there is some lubrication problem I'm not aware of. Any chance the rev limiter got bumped or your transmission was allowing the engine to over rev ? Cummins quickserve says the CTD is good for 4200 RPM for 30 seconds. That would be under a compression braking scenario, not making 700 HP though.

What really happened here ?

"heard louder than normal klatter the other evening wasn't sure if it was engine or drivetrain so I put in neutral while driving noise seemed less ,reved engine and that scary sound of a loud klangking in the motor .Soon as I got home I check the oil level and was all good ,while driving I check all gauges oil psi good ,temp ok,EGT normal, boost normal ,power seemed ok.
Next morning decided it was best to go to the Dealer 1/2 hr away figured I could baby the truck there the noise stayed the same for 20 minutes then got real bad shifted in to neutral rpm raced up ,shut it down pulled off road called for a tow truck this sucks. Got to the dealership oil spladdered under the driver side?? their diesel guy came out to look it over then started it and quickly shut it off his opinion was possible bottom let go"

What were you doing when the first "klatter" started ? Let me guess... driving to church ?

 

I bet I know what happened. I'll bet you used the box(es) from your 03 on your 05. I'll bet that you needed to run a different box on your 05. I'll bet you melted a piston that ultimately seized or damaged a bearing and this caused the rod to break.

 

super duty after the temp problem i decided to leave things alone til i could get some answers as did not like the water meth injection info and have been waiting on the bddl to be changd over for the 05 so i tried the tst but like i said before it created heat so until the the bddl returns nothing has been installed and the key is 5400 km there are alot of people running twins .sledpullers and more combos than we can imagine with out any rods poking through the block

so do you have any real input or you just a busten my *****

 

SD When i first heard the noise i was driving 80k which for you is close to 45mph at night not hot roddin no BOXES just crusin as i live in the country, shut it down and check the oil that was ok parked for the night then went right to dealer in the morning thought it was flex plate or something not this serious as i look here for possible causes

and this truck has never reved over 3200 -3300 rpm by the stock tach

 

If you play, you'll pay.

 

"and the key is 5400 km"

I'm not an expert, but I can only think of a couple things that will break a rod:

a) it was somehow defective to begin with
b) one of the bearings (connecting rod or wrist pin) seizes and thus puts a tremendous load on the rod
c) the piston seizes and puts a tremendous load on the rod
d) over revving

The bearing or piston seizing scenarios could be caused by lack of lubrication to that cylinder via a plugged crankshaft oil passage.

My 05 Cummins was very tight when I first started driving it and still is with 1500 miles on it. How many miles were on yours when you first ran the box ?

I'm very interested to hear the outcome of this situation. I'm dying to hear what the Cummins engineers have to say.

I've got a thing against people who hot rod their diesel and then go back to dealer and expect warranty when something breaks because of it.

I noticed that you traded your 03 off with a transmission with a shudder in it. Some poor guy is going to get a truck with a problem transmission. I see you are a fan of street racing and I see you were investigating various launch methods that might put extra stress on the transmission. Hmmmm....

I guess this is why I will never buy a used truck with a hot rodded diesel.
