Where the leaks usually occurs?

First leak was approx 10months ago, used store sealer r134a refrigerant and last until recently. Tried again but this time didn't work.

Compressor still turns on. Must be a leak or in the low inlet valve perhaps?

I'm not aware of any common leak spot. I'd guess the compressor but you're going to have to check. Use a refrigerant leak tester. Also, I would never recommend using any kind of leak fix as it usually causes more damage over time.

Condenser would be my guess, never put that stop leak garbage in

BRotato and Colin. Thank you for all the help and tips and your time.
I'm on the process of replacing the condenser and Orings and following your tips. I will go by steps since it seems that the condenser have visible worn out marks and more. Thanks a lot

As can see in first image expansion valve, the high pipeline was clogged by those tiny round things, unsure might had came from the dryer filter or else.
Replaced mostly everything except evaporator or pipeline was good condition. The lines had pressure but was clogged in the expansion valve end. So many things to change, it doesn't end. Evaporator inside cabin was a little uncomfortable to take all the plastics out to inspect.

replaced everything except pipe lines or evaporator. There seems to be a leak and noticed the valves leaking, both valves are new the low and high. Bought the set at AutoZone now I'm not sure what's the problem. Not sure if valves are standard or what could be but I will see how long the refrigerant will last. ​​​​​
