Ticking sound when accelerating

[94burb]

Hey guys,

I have some ticking sound that I only hear when I give it some gas while driving. I can't hear it during idle or when revving during idle. Any suggestions where to start?

Detonation maybe? You could try using a higher octane fuel to see if it goes away. If its anything more than that I would guess valvetrain noise, but that would also be heard at idle.

manifold/header leak?

manifold/header leak?

A more likely cause than my answer.

manifold/header leak?

Good guess with no more info than is given. Detonation is usually more of a clattering sound

 

[racer36]

Exhaust leak or some kind of vacum leak possibly. Any lose in power?

Donut gaskets.

I have to agree with the majority here. And the majority here is saying it based on actual experience. An exhaust leak at the manifold or at the collector sounds just like a tick when you're accelerating.

clicking is almost ALWAYS exhaust leak somewhere
is it especially bad when cold? -totally exhaust leak

This. A ticking sound that is most noticeable under acceleration is generally an exhaust leak. Most likely the donut gasket at the collector where the manifold and Y pipe meets, I would check those first. Could also be a cracked manifold, or hole in the exhaust system some where.
