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.
