In a bowl, mix olive oil, soy sauce, Worcestershire sauce, brown sugar, garlic powder, onion powder, black pepper, and salt to create a marinade.
Place the pork chops in a resealable plastic bag and pour the marinade over them. Seal the bag and refrigerate for at least 2 hours, or overnight for best results.
Preheat the grill to medium-high heat.
Remove the pork chops from the marinade and place them on the grill.
Grill the pork chops for 5-7 minutes on each side, or until they reach an internal temperature of 145°F (63°C).
Remove from the grill and let them rest for 3 minutes before serving.
