Review OEM or replacement installed

I have a problem with my valve cover gasket due to oil leaks. I've seen also that there is a leak with my valve cover gasket. I decided to get service with the said auto shop. One of the personel ask me if i want the OEM or the rplacemant parts install to my vehicle. I choose the OEM to make sure that the problem will fix. Since they have already the parts he said that i dont need to buy to CASA. I confirm 1st to the personel if he is sure that the item to be install to my car is OEM he said yes. They charge me 1000 pesos for the honda OEM parts and 600 pesos for the labor and 200 pesos for the solvent cleaner. Please look for the picture attach if OEM parts or local replacement parts. If not there is something wrong.
