Im worried about my car.

Car is: Ford Focus 2 1.6 109 cp DPF 

The sound appears within 1 minute after starting the car and remains until 2000 rpm.

What do you think about this sound?

Sound on youtube: 

 

When you say it remains until 2000 rpm, does it continue to make the noise at any time stops when the engine is running over 2000 rpm, or does it stop once you go over that speed and doesn't come back until the next time you start the car?  Does it happen under certain conditions e.g. only while revivng when stopped or only when accelerating?  Mine started making a similar noise when idle and there is a really obvious ticking noise from the belt side of the engine whenever I am accelerating under load until it reaches about 1500 rpm (whichever gear) and then it disappears, or maybe it gets drowned out by the rest of the engine noise.  I can only really hear it with the drivers window open, but as I don't see any difference to how the car drives I kind of just live with it now.

If you're referring to the ticking/knocking sound it's not too uncommon and usually is a sticky cam/lifter and various additives are available to help unstuck them if you want a quick and easy turnaround. Ask your local mechanic or motor factor which they would recommend if any. Some will say snake oil, but alas I have tried a few and they did help, it just happens that alot of the time the lobes are already worn some so the noise remains as they've been left untreated for so long.

I think I hear kind of a metallic sound in the very background of it all though too, is that part of what you're hearing? The mics pickup way different to our ears to a bit of description  would be useful 🙂

Hello, thank for the answer!

Since when does your car make that?

 

My car after 2000 rpm it doesnt make any sound.

As WWW says, it's difficult to make a clear diagnosis from sounds recorded through a microphone. Here's my two pence worth.

I have 2 1.6 petrol Focuses that make much the same noise. Just after startup, a noise much like you have recorded can be heard inside the car with the windows closed.

When on the move it is not so noticable and once the engine has fully warmed up it is almost muted.

To me it is classic piston slap and nothing to worry about. Below is an explanation of piston slap from the 'Bob is the oil guy' site.

https://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2522649

Piston slap is nothing new to piston driven internal combustion engines and compressors. It is the secondary (sideways or perpendicular) movement of a piston against the side of a cylinder bore where the primary movement of a piston is intended to be parallel (up and down) to the cylinder bore. All piston driven internal combustion engines and compressors have a certain amount of piston slap.

Excessive piston slap occurs when the clearance between the piston and the cylinder bore is too great. The piston to cylinder bore clearance becomes too great either through wear, mismatched pistons and cylinder bores at manufacturing or, a combination of both. The audible noise associated with excessive piston slap is due to the perpendicular impact of the piston against the wall of the cylinder bore. Audible piston slap is typically loudest when the engine is first started up. The pistons then expand with heat reducing the piston to cylinder bore clearance thus, reducing the perpendicular impact of the piston against the cylinder wall and its resulting noise.

I recon my cars will go to the scrap yard in many years time making exactly the same noise.

My car after 2000 rpm it doesnt make any sound.

Its had this noise for about the last 2 years.  I put it down to it being an old car and it hasn't got any better or worse over that time.

 

 

So does anyone know why this sound appears?

And how to get rid of it

I have the same problem I have mk2 1.6 auto sounds like swirl flaps not sure if focus have them though.
