An irregular ticking that slows downs over time is probably a hot exhaust component (exhaust manifold heat shield, down pipe, catalytic converter, etc.) contracting as it cools off. This is normal if it stops after a few minutes.

Without the year, make or model of your vehicle it could be a bad compressor and or a bad compressor clutch.............

The ac compressor is shot. Usually what your hearing is a bearing that is moving around.

Maybe that ticking sound is the ignition key switch in the steering wheel column failing to make enough contact to switch on. Also, it's possible your starter is shot. Obviously make sure that your battery is in good shape.

if your truck was out of oil and you ran it it probably threw a rod. it makes a fast ticking sound and it comes from under the valve cover. that is most likely what happened

funny you bring this question up....im 17 and bought a 1998 buick century with a 3100 sfi engine about a year ago. one cold morning i started it up and heard that ticking sound you mentioned. it did this for about three weeks before my motor blew up..what was it in my case? A blown head gasket. hope this helps

A bad transmission. The sound is from metal grinding on eachother.

The fuse box also contains breakers and relays.The clicking noise will be a relay clicking on or offMore serious cause:Or there is a breaker that is opening due to over load and resetting by itself. This is a very serious situation and may mean there is a short or other serious and dangerous electrical problem.

If they are mechanical lifters, then there is an adjustment under the valve cover. If they are hydraulic then there is no adjustment, and while a different weight motor oil or special additive may help the ticking there is not real way to stop it.

check exhaust for a leak. check starter motor and make sure the bolts are tight. you dont say if the noise is there while stationary or just when moving.

The ticking noice from under the hood comes from the cooling of the thin metal work near the exhaust system. The ticking is it cooling off and shrinking slightly.

The 2 most likely: A. Timing is off. B. Oil is low.

Is it accompanied by a shuddering or vibration? You could likely have bad brake rotors.
