Of course a 11 year old car is not still under warranty. The noise you are hearing is the lifters starving for oil at startup. Change the oil and filter and make sure you are using the correct weight and a quality filter. Add 1 can of Seafoam which you can buy at most Auto Parts stores to the engine oil. Drive the car 1,000 miles and change the oil again. Add another can of Seafoam to the engine oil. This may help clean and quieten the lifters. If the noise you hear is more of a knock than a tick you may have a worn crankshaft bearing. The only cure for that is a complete engine overhaul.

Collapsed hydraulic lifter? - try a quart of mystery oil

The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).

the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.

if ticking noise is in engine, u most likely have a worn hydraulic lifter. check oil for correct volume and viscocity

The cool water hitting your piping hot exhaust makes the metal contract (Shrink) and it makes a ticking noise.

yes, my 2000 grand prix gtp is losing power and makes ticking noise.

Most likely the ticking you are hearing is that from your solonoid. This is generally related with insufficient power from the battery.

from which part of your engine is the ticking noise coming from. if is the TOP it would most likely be lifter noise.try using a thicker oil.

Try to locate the ticking noise. Is it the engine? Is it ticking when you are driving? When you are sitting still? It could be as simple as a stone stuck in yoru tire, everytime it hits the road it ticks. it could be a lifter in the engine. Try to be more specific as to where and when the ticking happens.

My car was making this noise when I started it up. the noise went away after driving for a while. turnd out I just needed more oil.

Oil slow getting to the head

The ticking noise could be worn out rocker arms under valve covers. Switch to heavier weight oil if ticking noise subsides that could be your problem. This is usually a sign of a high mileage engine. Worst case scenario would be weak oil pump not getting oil to top of heads.

Bearing noise is usually deeper and comes from farther down in the engine. Lifter noise is more of a ticking and is up in the engine heads.

Possible lifters that are bad that could explain your ticking noise. It should cost you nothing by stopping by an Auto repair shop and have them listen to your engine.

98 Chevy new 383 block 30k, ticking noise from sounds like heads . 210k on heads;

Most likely it's your valves in need of adjustment.

Well if its sort of like a scratchy noise coming from the engine you might want to get your transmission checked out

"Engine temp is low 140 degrees" Bad Thermostat (stuck open) "a ticking noise is coming from the upper part of the engine" Lifters Make a ticking noise, To stop that there are these bags that fill with oil. If you run low on oil the bags don't inflate at you get a clicking. Check you oil level!!! The bags could be bad, the oil supply could be clogged, or something else could be wrong.

Sounds to me like HOT exhaust cooling down.

when i cut my car off and cut it back on its makes a ticking sounds, then i would have to get a jump then it would fire right up> we just go an 02 censor put on the car.

No! ticking noise is usually lifter noise. your engine is fine.(to a point) try changing your oil put in a thicker oil to prevent metal to metal contact. go for a 15/40 20/50. let it run for a while(few miles), if it doesn't stop buy an additive called "engine lucas", that will dilute your oil just enough to allow it to lubricate your lifters. also when your oil level drops or your oil becomes dirty your lifters will make that ticking noise.(the one that increases with engine speed) a blown head gasket 99% of the time will cause your car to smoke either blue or white.

If its coming from your engine, you may need a valve adjustment..

Ticking is not that that big of a deal to require a new engine. If your engine is knocking, it is a big deal. Make sure your car is ticking first. Ticking is usually caused by the valvetrain of the engine when it is not properly lubricated. As the engine increases oil pressure the oil makes its way into the valvetrain and the sound should go away. If it goes away when the engine is warm, it's likely ticking. If it is ticking, it sounds like you might be low on oil. Add a half quart see if it goes away. Then check your dipstick to make sure your are in the "safe zone." On some cars, you need to go above the "full" mark (ONLY A LITTLE, at most 1 quart over, which is about the same as the distance from full to low marks on the dipstick). It may need more oil, but use judgment from there. Hope that helped. I do not think it is a big deal, if your engine makes ticking noise. I drive my subaru seit 7 years with such kind of noise and never had any problems.. Do not replace engine for such small thing, most likely is your hyd.lifter a bit noisy. So what :)) Good luck.
