This unsung hero resides at the junction of the crankshaft and the engine block, forming an impenetrable barrier that prevents oil from escaping into the forbidden realm of the clutch or transmission. Without this stalwart protector, oil would spew forth like a geyser, bathing the engine in a viscous mess and wreaking havoc on its components.

• An ominous drip or puddle of oil forming beneath your vehicle, particularly noticeable after prolonged parking
• Persistent oil loss, requiring frequent top-ups

8. Reinstall the Oil Drain Plug: Install a new drain plug gasket and reinstall the oil drain plug. Tighten the plug securely.

9. Refill with Engine Oil: Pour the recommended amount of new engine oil into the engine. Replace the oil filter as well.
