Sticky valves. Go to an automotive parts supplier and ask for an engine oil additive to de-gum the valves.
Where is th ticking coming from?? The engine, the tires, the trunk????
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
ticking sound in engine is usually not caused by a timing belt ticking is usually caused by worn cam shaft or clifters most cars now have hydraulic lifters. if oil is low it will cause ticking. if a lifter is worn it will cause ticking these should have been ckecked for wear when replacing timing belt
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.
Faulty engine
yes, if its ticking bad and you like the engine, get it fixed
If it makes the ticking sound and the engine will not crank, then either your battery is dead or the starter solenoid is shot.
Ticking in an engine generally refers to the valves. If ticking is apparent on a 1994 Chevy Lumina tighten the valves to factory specifications.
lifters
Normally loose tappets will cause a ticking sound in the engine. Depending on if you have mechanical or hydraulic tappets you may need to have them replaced or simply adjusted.
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
Usually the valvetrain when oil is low.
