truck has come alive with annoying noises ;o)

lately i've been hearing a very subtle clunking noise coming from my belt/pulleys somewhere. it is definitely not belt squeak, and it seems to be worse when i first start the truck. it is intermittent; you'll hear some "clunking" for a second or two, then it will be fine for a few seconds, then more clunking, etc etc. kinda sounds like loose or bearings or something... i dunno.

any ideas?

 

how old is your belt ? maybe there is a chunk of rubber out of your belt somewhere.

 

shouldnt be more than 30k... it looks intact upon visual inspection.

 

Was the Hvac set to off?
was the engine cold or hot?

 

seems like the sound is much more obvious if the truck is cold. as far as the hvac controls, it doesnt matter if its on or off, clunk is still there.

 

Hey, whatever happened with tour fuel pump?

 

hehe fuel pump solved... it was the check valve in the sender assembly.

it's working flawlessly now (after a new sender heh)

nitrous coming in the next week or two :o)

 

very nice!

 

Not enough info to help you..
maybe get a piece of fuel hose or a "mechanics stethoscope"
and listen around for the area of the engine its coming from.

 

my truck makes the same noise and i think its coming from the power steering pulley... Like its stuck and then clunk fress up and starts spinning again then sticks again etc....

 

or it could be the timing chain it makes a loud clicking sound...which would me you really need to fix it soon or you have fun getting everything back in timing
