does anyone know causes a clicking noise during acceleration? acceleration is the only time it makes the noise, its quite during idle and when i get up cruising speed. any sugestions? thanks.

 

Does it change with vehicle speed or engine speed?

 

Sounds like an exhaust leak to me. Probably the doughnut gasket or else the manifold gasket. Acceleration is when you hear these problems the most. Sometimes that is the only time a small leak is noticeablemat all.

 

yes, the noise does speed up when the engine does. would it be form a hair line crack in the right exhust manifold?

 

If it's got a dark area around there, that might be it. If it's just a clean crack, then it's probably just on the surface. A manifold to head gasket is more likely for a ticking noise. Look around for a black streak, that's where the leak is.

 

Absolutely! If the manifold crack is a known fact then that is definitly what you are hearing. No worries! Get to it when you have the time and $$.

 

Also, check your U-joints. After you drive the truck, slide underneath and feel the U-joints. If they're hot, they're shot.

 

Perhaps your engine is pinging. Try a tankful of high octane and see if it makes a difference. If you notice a difference, a tune-up is needed.

 

Could be a fuel pump problem, make sure it is bolted down tightly.

 

thanks for all the sugestion. ill check them all out and post an update.

 

teah....be sure to learn the difference between "exhaust leak noise" and "valve tapping noise"....check yer oil to make sure the valves are getting what they need.
