my cummins is knocking help
 

Ok so I am kinda new to this whole dieseliss thing bought my first Gen cummins had the knock at the time I looked at it and I let my emotions over power logical thinking but I did drive the truck over 150 miles home with no issues idk what it could be cause the truck runs great

I haven't cracked an injector line yet to test for bad injectors I'm really hoping its not a thrust bearing but the knock kinda comes and goes ill fire it up sometimes and sounds normal turn it off and start it straight back up and the knock is back

more than likley the bearing if its still runnin strong.....

What is your oil pressure like? is the knock down low or up in the head somewhere. If at the upper engine (head area), could be a failing or failed injector. Down low,.......well you know. Check the oil for metalic hue or metal flakes. Change the oil and see whats there.

I can't really tell if its up top or down bottom I'm still using the factory gauge on the dash it takes a Sec when u start it and slowly moves to about the 3 to 4 th notch over usually stays between them two but my last two injectors stay wet and there is black stuff on the hood above them?

My second gen blew the crush washer on the number 6 injector and spit fuel and soot until I replaced it. It didn't knock, though. Sounded EXACTLY like an exhaust leak (which is what I thought it was until I found the wet injector.

I wish I new more about diesels that would be a huge help but this is the first one I've ever ownd so I'm kinda Learning as I go I can't pin point exactly where the knock is comn from cause if your over the top it sounds like its up top but if your under it sounds like its down bottom

Well, I don't think you've spun a bearing. Your oil pressure will either spike (because the bearing blocks the oil journal), fall to nothing (if it's real bad) or go back and forth between the two as the bearing continues to spin. Drain the oil and look for signs of metal dust/shavings/chunks or pull the pan and peek up at the bottom end.

If the valves are way out of adjustment it sounds similar to a knock, but it's pretty distinctive. Maybe you just don't know the difference because you're new. Adjusting the valvetrain is easy and doesn't take that long.

I've had a couple people say it sounds like a valve but I'm just trying to get a good opinion from people who own or have worked on these trucks its deff not a rod type knocking sound my turbo sucked a dirty filter shut and when I replaced it it quit and sounded fine but when I fired it back up it started doin it again I'm pretty good with gassers but this is a whole different world to me I app all the input from u guys

Good Lord, talk about a run-on sentence.............
It may be a failing injector, excessive carbon build-up in a cylinder, or maybe even a noisey wrist pin. Hard to say really without hearing it.

Ooh, noisy wrist pin. Didn't think about that. Then it would definitely sound like a knock in the top and bottom.

Smart man.

I hope not but well will see when I put it in the shop. If it dose have a wrist pin issue how much do is that going to run me vs like injector rep and bearings?

Don't know. Never let anyone wrench on my stuff for me before. Especially if I have to pay them.

No I just don't have the means nor the time I work a second shift job and live in a town house with no garage and married at the age of 23 with a 1 and a 3 yd old so my wrenching time is extreamly limited.I really don't have a choice in the matter I'm driving my cummins as a dd with no reverse and a crap ton of other issues I'm doing the best I can

Jesus, dude. Just breaking your balls a little. No need to get all salty and bum everybody out.

Kudos to you for taking on such a huge challenge!:tu:
Now Im gonna go find a shrink to talk to...........I need a hug :s:

I took a vid of it running so I could get some better input from you guy how do I upload it or can I ?

Put it on photobucket and paste the link here.

Well, take away the sound of the bird farm, that actually sounds like an injector hammering.

Sorry bout that belt it gets a little annoying thank u and who makes a good set of injectors for a non ic truck I don't need any thing crazy just to give me a good boost in power

A new set of stock injectors will give you a "good boost of power" if that awful racket is indeed an injector. It it were me, I'd get the thing in sound, stock condition, then use that solid foundation to build your monster on. That's just me, though.

That's what I was thinking about doin I'm hopeing that's what is wrong. I would much rather replace injectors then half to rebuild
