Ticking sound !

[EErmert]

disregard thank you

That's very similar to the problem I am having with my '04. No tick at idle but as I accelerate the ticking increases with rpm. I added power service as I don't tow or drive far anymore. 5 minutes to work each day. I figured it was carbon build up. The power service cleared it up, but I'm waiting on a reply from TWest on his suspicions. Might be that there is another problem. I recomend you add some power service and drive it a bit and see if it goes away. From what I have read these trucks need to be worked or they get alot of carbon build up in them. I might see if I can take it in tommorow and see what the dealer can find doing the injector shut down test.

Check the injector supply line clamps. If one is loose, it can cause a noise.

That may not be the problem, but it's something very cheap and easy to look at first.

is it possible that he is hearing a u joint binding up from rust in the caps? would click or squeak only when under load.

 

[EErmert]

Well thank you all for the reply's so far, actually, it's more of a mechanicalsound, and only when under load... will ck injectors, lines, etc, etc. The ball joints is interesting...

This loose injector supply line noise is an interesting concept. I have recently noticed a tappet like sound coming from the front of my 06 CTD. It is the loudest through the radiator or standing in front of the truck at idle.



It is something that is sometimes louder or quieter. I tried feeling each external injector line while the engine was idling.

Strangely, when i felt the #1 injector line, the noise seemed to correspond with a knock I felt in the #1 injector line.



Is there a way to look into this further without going to a dealer. Most dealers around here don't have any competent diesel techs.



There are no clamps or attachments on the #1 line going into the head. If I remove the rocker arm cover, will it be obvious what needs to be checked and tightened??



If so, can any other member provide some mentoring?



Thanks, Chuck

That's completely normal. The #1 line has the longest unsupported span, and will always knock more than the others.

There are no clamps or attachments on the #1 line going into the head. If I remove the rocker arm cover, will it be obvious what needs to be checked and tightened??

Once under the valve cover there are no more supports for the injector lines. The distance from the side of the cover where the supply line enters to the injector is only an inch or two. It is possibly for an injector hold-down to be loose, though. There are two screws that hold each injector in place, and they are fairly obvious once you remove the valve cover.

rbattelle,



Thanks for the info!

rbattelle,



Sorry, I forgot to ask, if the knock in the supply line is normal, is the slight engine knock,(heard best through the radiator) that seems to correspond with it normal also??



Thanks,

disregard thank you

So, what was the outcome? I'd sure like to know what you found to be or not to be the problem.

Ooooo, that's a tough one without actually listening for myself. I would tentatively say yes that's normal too. Remember what a 12v or 24v truck sounds like? Well, deep down in it's soul the common rail truck is the same fundamental cycle. It's just been quieted by extra fuel events (particularly pilot injection).



What you're hearing through the radiator might be noise from the CP-3, which is noisier than you think.



I wouldn't be too concerned with a knock that is "slight" and heard mostly with your ear to the radiator.

Ryan,



Thanks again. I will keep an ear on this noise. If it gets louder, then I will take further action.

Ticking noise also.

Need help in trouble shooting ticking sound at certain RPM. Actually had multiple sound issue's One being the water pump. Replaced water pump and had one less sound issue. Second was exhaust leak at downpipe. Tightened bolts which really were not that loose and I think that issue is gone. Did a soapy foam test at connection of down pipe and that seems to be ok.

The third issue is a ticking or rattle sound that happens at about 1800 to 2000 RPM. It seems to be consistent at that RPM. This is while in park in the driveway. Truck runs great. I have the smarty set at level 9 which is the most aggresive but I still get 15 to16 mpg. My main concern is that it is something internal. Valve's,bearins,push rods you name it. To complicate things I can not hear worth a dam. Should I start with the injectors which seems a likely culprit or??

Your thoughts .

Thanks

Mike

 

[MFranz]

Anyone have any thoughts?Worst case scenario?

Thanks Mike

Oo. Oo. Oo.

 

[rbattelle]

The third issue is a ticking or rattle sound that happens at about 1800 to 2000 RPM. It seems to be consistent at that RPM.

Is this on your 2001? The B-series has a resonance right in the 1800-2100 RPM range which is considered normal. If that's what you're hearing, then there's nothing to worry about.



What's the fuel pressure at your VP-44? What type of lift pump are you running? And how in the world can you identify a tick in an engine as loud as a 24v?



My advice would be not to rev the engine to 2000 RPM in park. Or neutral.

Ryan,

I have an AirDog fuel pump and pressure is around 12+ PSI. I have driven the truck for 110,000 miles and have not heard this sound before. I have read a lot

of post dealing with engine noises and thats one reason I was able to locate

the trouble with the water pump. Your right its very hard to hear anything on the 24 valve,especially when you are half deaf like me. My biggest concern is that it is something internal. All my gauges look good and truck runs great

but?????????????

Thanks

Mike

Noises are very hard to diagnose over the internet. What am I saying - almost everything is hard to diagnose over the internet!



I'm certainly no 24v expert, and you might get better ideas from the 2nd gen forums. If all the gauges read normal and the engine runs well, I wouldn't worry too much.

I haven't been adding Power Service fuel additive lately and just did. Now I don't think I am hearing the same sound's It's enough to drive you#@$%!#@$%!. Thanks for the input and here's to keeping our ears to the ground I mean engine.

THANKS

my truck does the same thing and has me nervous as well ISthere anything to reserch on this "noise"?thanks in advance. 2005 ctd 21,403 miles

 

[TJarecke]

Not sure if this is the same or not but, my brother's 03 started making a noise yesterday. It is mostly noticable in 5th and 6th gear from 1700 to 2200 rpms.
I thought it was a front end issue because there is some vibration too. I only drove it in town and only as high as 5th gear. He said it was worse this morning in 6th. So it seems to be more of a rpm issue than speed issue?
Truck has Edge juice, intake and exhaust.

Ideas? Hopefully this is a addition to the thread and not a hijack.
