In most cases, you can tell that your lifters are bad, in your car engine, by the ticking noise. A bad lifter will make a tapping sound.
The tinking sound if it is a light sound is probably the fuel injectors working which is normal but I would check the oil level and make sure it is full first it could be lifters ticking or clattering.
The ticking sound is coming from the valve lifters. When the oil filter is changed, air is introduced into the system, which causes air bubbles to form in the oil. This causes the valve lifters to "leak down", which is what causes the ticking sound. It can take several days for the bubbles to dissipate. It's annoying, but harmless.
Lifters ticking.
More than likely it's the lifters.
Dodge Rams are known for their ticking due to "noisy lifters". This problem has been ID'd by some individuals as Dodge's use of cheap Chinese made lifters for their 5.7s. To get rid of this you would actually need to replace the lifters with after market lifters. Now if you're referring to a tapping+fluttering sound when you accelerate then you will most likely need to check on your valves.
Lack of oil lubrication to lifters
the lifters may need adjusting or replacing. your engine not getting enough oil causes the lifters to make noise. not sure what motor you have in it but if it's an engine where you can tighten the lifters then you can buy a tool for it if you know what your doing
well it sounds like your lifters are ticking The connecting rods screaming LET ME OUT!!!
Fuel injectors can stick and sound like lifters but not as loud. Lifters of course. The speed of the ticking would help, one or two cylindars or all of them? A spark jumping, but there should be some loss of performance.
Get your brakes tested. I do not know what a ticking sound means.
It's a rocker arm tapping at valve stem. Hydraulic lifters (hydraulic rocker mounts) are the common reason for the ticking. If it doesn't go away when the engine heats up, consider replacing the lifter where the ticking comes from.
