The "tick" of the engine is caused by the pre-ignition in the chamber before it reaches the spark plug. Because the gas is combusting before it reaches the spark plugs, this is causing the "tick" noise. Recommend using a higher grade of fuel "mid-grade" Have you checked your oil lately? If not check it and if it is low add more and the ticking should go away. are you sure you are not hearing the normal noise of the fuel injectos doing their job? a properly-working fuel injector will make a clicking noise. Some times you can hear it while driving in a quiet place, or when the engine is running and you are under the hood. THAT is a normal sound. answer not pre-ignition. ticking sound is more likely to be a small exhaust manifold leak. or a sticky hydraulic lifter, an engine flush and oil change will fix it ANSWER FROM DAN

the ticking noise may be your lifters if you put new oil in and the ticking does not go away try tightening your lifters. you may want to take the car to a garage because you could wreck more than help if you over tighten. or don't fit gasket correctly.

Why do you have to burn ticks?

The reason most people burn ticks out of skin is because the heat from whatever they are burning it with makes the tick back out of the skin. If you just ripped the tick out the head would and or could detach and cause a sickness called tick fever that is most times fatal.

Why does a BMW E46 gasoline engine tick like a diesel engine?

First, is it a tick or more of a clatter? (I know, I know, not trying to slit hairs here, but its important) A light tick could be anything from insufficient oil level to excessive valve lash (not sure if this is an older pushrod or newer hydraulic lifter engine, sorry). If its a deeper clatter (more what I think of as "diesel" sounds) then it could range from something as simple as premature ignition timing (spark knock), which could just require an adjustment to the distributor, to something as serious as rod or main bearing knock (very serious indeed, requiring an engine rebuild to correct).
