Hopefully just a valve lash adjustment.
Your valves need adjustment. Take it to your preferred mechanic.
That slight ticking sound is probably the injectors firing which is normal.
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.
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 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.
I don't know, take your car for a check up and tell them about it...
Lack of oil lubrication to lifters
the ticking is the blinkers
Get your brakes tested. I do not know what a ticking sound means.
that's just the sound of the steel bits cooling down
there is a dust cover behind the front rotors they sumtimes bend slightly and it causes the ticking and crackling
