when i pulled in to fill up with diesel I gou out of my truck and herd a ticking noise. it is in no certen pattern tick tick....tick tick tick......tick.... ticktick...
but i beleice it is comming from underneith. does anybody know what this is and should i be worried about it and also another thing it doesnt do it all the time.

 

do u think someone can actually tell when all these engines do is make ticking sounds from everywhere ?

 

well its very unordinary. it stands out it almost sounds like its a spark? but im sorry i thought this was a place to get help

 

Could be the serpentine belt or idler pulley. Check the belt for cracks or pieces of ribs missing. Take the belt loose and spin the pulleys by hand to check for roughness or noise.

 

Exhaust system cooling down?

Could be the exhaust manifold is cracked. Mine would really PING, 3-4 with several clicks in between. I replaced the manifold with an ATS and it is gone.

They start cracking usually on the bottom side of #4 cylinder exhaust (#1 being at the front) and the crack works it's way around to the top of the exhaust pipe. You can see it better with an inspection mirror or from underneath with a flash light.

 

Engine running or stopped?

Hard to discern from the original post.

(based my exhaust system cooling down on the engine being shut off)

while its ideling

 

check to make sure that you dont have any exhaust manifold bolts broken off. Mine ticked like crazyyy when I had one broken off. Once I drilled it out and put a new gasket and bolt it, I dont even know that 12 valve is there...

 

I hear a sound like this on my 05, if you go to the rear of the truck while its idleing I hear a faint but noticable tick...tick...tick, I thought it was an injector going out but its still going 30,000miles strong.
