Coolant leak from the engine bolock? ist thats possible?
I have noticed little coolant leak from engine block or from one of hoses. It leaks about one drop a week. But the smell in the car is nasty because of that... Does anyone know how much it will cost me to fix that? And is it possible to fix it myself?

Any white smoke from exhaust at startup? If so, cracked block. $$$$$$$$$. Take it to your service guy and perform a pressure test on the cooling system to identify the source of the leak. If its a bad hose or clamp $$ by comparison. Good luck.

Is there any other way to find the leak spot?

ah, there is no white smoke at startup.

I still think the best way to find leaks is to shine a UV light around under there one evening. You can follow the trail of antifreeze right to the leak.
Most times leaks are because of old hoses or loose clamps. You can take a wrench to all the clamps you can find and tighten them.
If it has been REALLY cold there (like 50 below) its possible one of the freeze plugs might have cracked loose.
But you should either have it pressure tested, or get a UV light ad track down the leak yourself. Dont just let it leak.
