Who Has the Rattle / Clatter / Knock etc???

David, I will add myself to the list from what I have heard my noise is similiar to yours but less. It occurs at lo or no boost with a moderate amount of pedal pressure on the accelerator, baby the throttle and it doesn't occur and mash it and it occurs for a split second then is gone when boost comes in. It sounds like an old ***** gargling marbles. My mods list is
Stock bottom end
F1 cam and springs
Flux 3.3's
Twins 62 over 480
PPE dual pumps
Smarty programming and that's it except for some pressure with Power Puck

Well as far as mods go, You and I are VERY similar except for pressure box but pressure is pressure!!!



LIST:

Big Swole = David Elrod
Triton = Ty
onetun
soulezoo
EPA Violator = Jay
HIGH TECH RAM
 
cbtoyz=Colin Beddow

Sounds like timing rattle till I get around 10-15lbs. of boost.

I have had the head off several times, starscanned, injectors tested, rail capped, and have found nothing. I am just going to run it till something breaks, then build it better!

Mods...
Smarty
Mp-8
FASS 150/150
PPE dual cp3
DDP 200's
Twins 62/71/.8 - s480
Studs
O'rings .009
Modified 12v gasket .020 thicker than mls.
Billet tranny with Goerend parts
Ext...

I have the noise some also. It gets worse the more throttle you give it, without boost. As soon as boost comes up it's gone. Sounds like a nasty timing rattle. It does it with Smarty on various timing settings, and in stock programming. Rail pressure isn't that high because I'm still runnig the stock cp3 until later this week. Correct me if I'm wrong, but I'm the only non 600 series on the list. My mods. are
Smarty TNT
TST
DDP180's
HTT64/71-13ss
stock bore pistons minus .050
stock MLS head gasket

Something interesting I read, may hold relative to this problem.

That is interesting. Basically I interpret that as advanced timing injection with lowered compression = more noise. So, the compression is already on the low side to combat nox and we who lower it even more get the noise.

FWIW, mine does this on stock programming. I think smarty advancing timing makes it more pronounced.
 
This is something we kinda already knew but, it gives reason for the knock/rattle. I think with our larger injectors plus added timing ( or not ) we've helped to eliminate the pilot injection or made it so large it's not doing what it was designed to do. It's possible we've turned our trucks back to 24v with one injection event.

Pilot injection, what this achieves is the creation of a small explosion immediately before the big bang to give a gradual increase in combustion chamber temperature, rather than allowing a sudden one. It's those sudden temperature increases that cause the familiar diesel knock / rattle.

I Just went larger on the Injectors So know I'm really curios as ho its going to sound with the lower compression . I should know by the end of the week.

I thought I had a rod knocking a couple of weeks ago at the track. Everyone could hear it in the stands. Hard to catch it in this video though.

I run the Smarty TNT on timing level 3, no rail pressure, Tq on 4, and run Level 7. It's more noticable in the morning, but gets better as it gets warmer. Still never goes away though.

I just have the Smarty, F1 Flux 2.2, and a bag of parts from II on the truck. It's an early 04 305/555
 
I think you might have something else going on. I can't speak for every one that has the knock but, it gets worse as the truck warms up and at idle can't be noticed as much.

You may want to look into yours deeper before you melt a piston if you haven't already. Swole that started this thread was driving around with a melted slug and didn't know it except for hard starting. Ended up finding 2 bad injectors and a melted piston. Don't believe it was knocking like that though
 
It only did that when I bumped the timing up to level two and ran Level 9 on the Smarty, otherwise, I just get a little rattle at low boost.

Still trying to find the right tune.

I don't have a common rail, but out of curiosity, what model year engine is this happening to more?

03-04.5, 04.5-06, or 06.5-07.5?

I think I broke it down the right way...

I get it too, with the 06 truck in my sig, stock pistons, .20 over HG

had a few bad injectors, 2 melted pistons... we will see if its gone, once the motor is back together again

I feel for ya man!!! These damn CR injectors!!!!

Has ANYBODY had better luck with the new S.S. injectors bodies from Bosch....Anybody know of an S.S. Failure yet???

Rattle on my 05 motor in the Ford

03 Dodge, Scheid Injectors, Dual CP3's, Smarty TNT/R HTT66
No Rattle
 
Mark me down.

I still have it with stock sticks, stock cp3, twin turbos, and a FASS.
