Since I replaced my motor in my 99 24v there has been a strange knocking noise. Every one I asked around my town that has a cummins said it sounded like a fuel knock. So i had an extra set of stock injectors laying around so I cleaned them up and put them in. When I pulled the old ones out they where all soaked in fuel. Now the new ones are in and still the same knocking noise. So i ask all my buddies again and they all said that is what there trucks sounded like with stock injectors. Just wanted a second opinion i no you guys would have to hear the truck but if you have any idea's I would greatly appreciated.

Thanks Chris :nail:
 
I know all the trucks I have heard with stock injectors run a little louder than after market ones but ive always thought mines had knock to but its been holding together over 4k rpms lol
 
i am going to try and add a video. But half the diesel mechanics say it sounds like a fuel knock. The other half said it sounds like a stock cummins. Video will be up asap

Thanks Chris
 
If you guys want to hear the noise give me your email. I cannot figure out how to post a video on here
 
No it doesn't sound like that rochie. did you ever find out what that is though? And my my knocking noise goes away the higher the RPM

Thanks Chris
