Got a new rattle to the old cummins..

Posted

Hello all. Sorry I havent been on much lately. Just been so busy with work and moving again.

 

Anyway, I noticed the other day that my old cummins is extra rattly, especially during shut down. It almost has an extra thump-thump to it. I cant tell if it is just something loose under the hood or internal engine. I am very much hoping for an easy fix.

 

I have a couple videos I took of it. You can definitly hear the extra rattle as the engine shuts down and a little bit of the thump while its idling. 

 

Video 1

 

This video has a loud thump at the very end but that was just my phone hitting the dash as the mighty engine slows down.

 

Video 2

 

Hope the videos help describe what I am hearing. Any ideas?

The second video was much better.  If it were me I would start by checking motor mounts, exhaust hangers and transmission mount.  I had something like that a long time ago and it was a bad transmission mount.  I assumed it was a sound associated with shut down on my truck.  When I installed a new clutch in '08 I found out the mount was bad.  Put a new one in and the sound was gone.  I am the second owner of the truck and it did that since I bought the truck a few years prior.  I did not think anything of it up till that point.

    Is there a certain way I can check them mounts? Just get under there with a big pry bar and move things around maybe? Also, how much play should either the motor mounts or transmission mounts be allowed to have? Not much I would assume...

    Besides a visual inspection, you can open the hood and watch it shut down.  It should not move a whole lot.  Also a floor jack could be used to lift the engine and transmission lightly to check.  It don't take a whole lot just enough to move it .  Just some thing's I have done in the past.
