Why do I hear a ticking noise in my car?
Gravity will keep what oil there is further down in the engine. If oil isn’t reaching the top of your engine, you’ll begin to hear a higher-pitched ticking or tapping noise. More often than not, this is coming from the engine’s valve train components like lifters, rockers, camshafts and cam adjusters.
What causes the tappets to drop in an engine?
Over time, as engine oil starts to gather dirt and increase in viscosity, the interaction between the camshaft and tappets begins to wear down both components to a point where an audible noise can be heard between them as the camshaft spins and the lobes lift and then drop the tappets.

How does the O2 sensor in a car work?
The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.
How do I remove the O2 sensor from my Mercedes Benz medic?

What can I do about tappet noise in my car?
An oil additive can also be used to clean valves, rockers and tappets without affecting the viscosity of the oil, keeping the valvetrain in silent harmony. If these changes make no difference to the tappet noises, a full tappet adjustment should be the next move.

Why does my cylinder head make noise when I adjust the valve?
In any hydraulic application, another cause of valvetrain noise can be the result of machining of the cylinder head and valve seats, which changes the rocker-arm geometry. Many mechanics think that this is caused by faulty hydraulic lifters; that is incorrect. The lifter is only responding to the conditions and trying to adjust for them.
Why does my car make a tapping noise?
Re: the tapping. It’s probably not hurting the engine. A little extra valve clearance or some piston slap will make this noise, which can be disconcerting, but no measurable harm is done. You might do well to reconsider using the 5W40 oil and the additive.

Why does my motorbike engine make a noise when I start it?
Start out by listening at different points around the engine, like the cylinder head valve caps, or the camchain tensioner mechanism. An engine will often sound noisy on start-up because components aren’t under load, the engine is cold and the oil hasn’t warmed up and started circulating freely.
Why does my water make a rattling noise when I Turn Off the tap?
The technical term is hydraulic shock and it happens when the water suddenly changes direction – all the water that was rushing through the pipe is forced to change direction when you turn off the tap. Before the water can change direction, it crashes into the valve which causes the rattling or knocking sounds.
