To unseize spark plugs, first, apply a penetrating oil around the spark plug base. Let it sit for about 10-15 minutes. Using a spark plug socket and ratchet, gently try to turn the plug counterclockwise. If it resists, apply more oil and allow additional time. Patience is crucial to avoid damaging the threads. Consider heating the engine block slightly to expand the metal if the plug remains stuck, but proceed with caution to prevent burns.
