So i replaced the following: CP3 pump, tank pump & all 6 injectors, and is running sweet! Valves were a little noisy(181,000mls) so i adjusted them, now i seem to hear a noise (clacking/ticking noise towards the front, around the balancer under truck, (did the old screw driver to ear) noise is very noticable. Is their anything in there that would do make this sound,(does not sound like a rod knock). Most noticable at idle, very slight while driving???

 

there are lots of gears in there and can make some noise

 

Well i took it to a diesel shop today and sad news! rod or piston knock!!Their checking into a long block ***. from Jasper we'll see what the quote is, I,m thinking 3,500 for long block + labor (if i didn't like the truck i'd put it in the lake!!!!
