It has both.
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
Could be the timing is a little fast.
Could be, Out of adjustment Worn camshaft Worn lifters Worn pushrods Worn rockers All of the above.
if it is cracked or the gasket is bad sometimes they sound like ticking lifters. look for carbon deposits at joints and on the manifolds themselves.
Could possibly be a bad lifter.
i have that problem. i was told it was the lifters, but it's a pricey job. that's the best i can do for you. i believe you have to remove the head gasket in order to get to them. -NEW ANSWER- I HAVE THAT PROBLEM ALSO... MY MECHANIC TOLD ME THAT THAT SOUND IS THE LIFTERS, BUT WHAT IT ACTUALLY IS DOING IS THE LIFTERS ARE TAPPING AGAINST THE DIPSTICK IN THE CRANKSHAFT. HE TOLD ME NOT TO WORRY, IT IS AN ANNOYING SOUND BUT IT'S NOT DOING ANY INTERNAL DAMAGE TO THE MOTOR... IF YOU WOULD LIKE TO GET RID OF THAT SOUND, THEN YOU WOULD HAVE TO OPEN THE HEAD, AND HAVE THE LIFTERS REPLACED. The Crankshaft is nowhere near the lifers. It's the rockers slapping against the lifters that you hear. Not much of a problem if you don't mind the noise, just keep an eye on your oil pressure.
The most likely cause of a ticking sound in a motor is a bad timing belt. A valve out of time can also cause a ticking sound.
It is probably the lifters. I suggest using an engine flush and I have had luck with GUNK. Follow the directions on the can. You may have to do it every 30000 miles . I found that if I put a non Mitsubishi oil filter on my pu would start making that ticking sound
it will cause the engine to overheat and also coolant to enter the oil system, which will in turn cause wear of the lifters.
a "knocking" noise could be your lifters. and the ticking when accelerating and letting out of the gas is the same thing. check your oil and if it's full then you may need to think about either having them adjusted, or getting new ones. depending on what you have depends on whether or not you wanna sell it
look for a shorted electric motor like window motor. when the motor contacts fail they can cause the "ticking" and it drains the power constantly, even when the ignition is off.
