Truck ticking loudly

[Turbowski]

Hello all,

I have a 2006 Cummins 4x4 and the issue I am having is that the truck sounds perfect at idle. When I start to accelerate there is a loud ticking coming from the engine bay. There are no lights on the dash at the moment.
Also, about every fifth time I go to start the truck it seems to want to crank for a longer time then normal. usually around 4 to 5 seconds roughly.

Could this by chance be the injector tubes? or worse. Thank you all

Also, When the truck is in Park and I give it a little gas up to around 1500 rpm, it stutters and stumbles back down to idle.

Have you checked your #4 injector line hold down for tightness? When those guys get loose they can definitely cause a ticking noise.

I don't think you can go wrong torquing the injector tubes, doesn't take that long and it's free. I suggest removing the entire rocker box for best access.
