What could cause an engine to 'tick'?

The "tick" of the engine is caused by the pre-ignition in the

chamber before it reaches the spark plug. Because the gas is

combusting before it reaches the spark plugs, this is causing the

"tick" noise. Recommend using a higher grade of fuel "mid-grade"

Have you checked your oil lately? If not check it and if it is low

add more and the ticking should go away. are you sure you are not

hearing the normal noise of the fuel injectos doing their job? a

properly-working fuel injector will make a clicking noise. Some

times you can hear it while driving in a quiet place, or when the

engine is running and you are under the hood. THAT is a normal

sound.

answer not pre-ignition. ticking sound is more likely to be a small

exhaust manifold leak. or a sticky hydraulic lifter, an engine

flush and oil change will fix it ANSWER FROM DAN

the ticking noise may be your lifters if you put new oil in and

the ticking does not go away try tightening your lifters. you may

want to take the car to a garage because you could wreck more than

help if you over tighten. or don't fit gasket correctly.
