Hello, I have a question. For a while now, when I start the engine, I've been hearing an unpleasant "rattling, knocking" sound coming from the left valve cover.

I thought it was a problem with the lifters, and I think it is, but I don't have the knowledge to determine it myself.
What should I do in this situation? Replace everything?

What could be the problem here?

Greetings from Poland

If the valve is closed and there’s no pressure on the rocker they jiggle freely like that. Put the covers back on Post another video with a cold start.
 
The side to side play is normal. The shaft wears on the underside where they contact the rocker arm, and the rocker arm wears there as well.

Does any single valve have more lash than the others when the lifters are bled down?
 
"but I don't have the knowledge to determine it myself."

Guys,
Please keep in mind what the OP stated about his experience with engines/valvetrains and keep your suggestions simple (like @detmatt did with his good troubleshooting suggestion). I've seen time and time again here where someone who is looking for advice for a problem soon starts getting suggestions for roller cams, Jessel titanium rockers, aluminum heads, gear drives, 10-quart oilpans, superchargers, turbosuperchargers, replacement engines, replacement cars..................
 
another common misconception with ticking/slight knocking sounds, is when the exhaust manifold gaskets gets a blowby.

I recently got a similar sound, loud ticking near the left engine side, just after start-up, which gradually goes away almost completely after warm-up , but is still noticeable.

Found it to be an exhaust manifold gasket which is leaking. I can even smell a little fumes in the cabin now, when driving. Simple repair.
 
A couple questions are in order. Since the description sounds like lifter noise..... Does the noise go away after the engine warms up? Is the car being driven? What oil? How long since the oil change?

The easiest things it could be are lifter noise or exhaust leaking at the manifold. If it's lifter noise, probably the first thing to try is getting the engine hot and draining the oil when it's hot. Then replace oil and filter.

If it's the exhaust leaking, look to see if someone installed a gasket under the manifold. There shouldn't be one. If there isn't give the manifold bolts/nut a little tightening and see if it improves.... Actually, if there's a gasket, try that too, but usually that involves pulling the manifold, cleaning it up and reinstalling without a gasket.
