Lack of oil lubrication to lifters
you need to adjust the valves
lifters
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.
The electronic ignitor keeps ticking when it is off because it is cooling off. The air hits the probe when the probe is hot, and it is trying to condense, or cool off, which causes the ticking.
there is a dust cover behind the front rotors they sumtimes bend slightly and it causes the ticking and crackling
Condensation
It may be as simple as checking your tire pressures to see if they are equal.
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
A hot water tank will tick when the temperature of the water is reached and it is starting to cool down. The ticking is because the metal of the tank is warm on the inside and a little cooler on the outside.
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.
What causes ticking, check engine light, and the check gauges sensor to come on in a 1999 Dodge Durango 5.2L SUV?
Hopefully just a valve lash adjustment.
