Re: "tick tick" sound from my engine
the cause of the sound is tappet noise, it will happen when your engine is started cold, when the engine warm up and engine oil start flowing nicely, the sound will disappear. unless the sound refuse to go away, otherwise it will not be harmful to the engine. if you are really bothered by it, try flashing your engine oil, as it could be due to the quality (cleaness) of the engine oil, changing the engine oil might help.
