The Porsche 99911326340 crankshaft front seal is a genuine OEM part for 928 models (1978–1995). It seals the crankshaft at the front of the engine, preventing oil leaks and protecting vital components.
Fits:
Porsche 928 1978 - 1995
Diagram ref no 3
The crankshaft seal’s job is to keep the front of the engine oil-tight and prevent leaks. By containing the oil, it protects belts, pulleys, and timing components from damage. It also helps maintain the correct oil level, ensuring proper lubrication and long-term engine health.
Signs You Might Need It Replaced:
• Oil dripping or pooling at the front of the engine or under the vehicle near the crank pulley
• Visible oil seepage around the crankshaft front seal.
• Belts / pulleys becoming oily, or clutch interference (if oil sprays back)
• Smell of burning oil (if it contacts hot surfaces) or smoke.

Front crankshaft seal also known as a shaft sealing ring. It sits at the front of the engine, sealing the point where the crankshaft passes through the engine block - typically behind the vibration damper or timing gear. Its purpose is to keep engine oil contained while allowing the crankshaft to spin freely.

Over time, the crankshaft seal can wear down from constant heat, oil exposure, and friction. The rubber lip may harden, crack, or become damaged, losing its ability to seal properly. When this happens, oil begins to leak, which can create a mess, damage engine components, or cause belts and pulleys to slip if oil spreads across them.
How to Know If It’s Failing:
You might suspect the seal is failing if you notice:
• Oil dripping or forming a puddle under the front section of the engine.
• Visible oil seepage around the crankshaft front seal area.
• Smoke or burning smell under the hood (oil hitting a hot surface). Low oil levels without visible external damage.
• After so many miles or long periods without seal maintenance, even if there’s not a massive leak yet.
If a worn front crankshaft seal isn’t replaced, the oil leak will usually worsen over time. This can lead to significant oil loss and starve the engine of proper lubrication, causing serious internal damage. Leaking oil may also spread onto belts and pulleys, leading to slippage, premature wear, or even belt failure. In addition to making a mess and degrading nearby components, oil on hot surfaces can pose a fire hazard. Left unchecked, the problem often becomes more expensive to fix, especially if the leak reaches sensors, wiring, or other critical parts.
