Oil Seal Crankshaft Front Opel Astra H + Astra J + Vectra C [VAP Auto Parts] (Made in China) (20031720B)
ENGINE SEALING: VAP Auto Parts Front Crankshaft Oil Seal (20031720B) – OE-Spec for Opel Ecotec Engines.
END FRONT OIL LEAKS. PROTECT YOUR TIMING SYSTEM. INSTALL THE HIGH-HEAT SEAL BUILT FOR OPEL'S 1.6L/1.8L ENGINES.
The Front Crankshaft Oil Seal is a critical engine gasket that prevents pressurized engine oil from leaking out where the crankshaft pulley (and often the timing belt/chain) enters the engine block. On popular Opel models like the Astra H, Astra J, and Vectra C (which share common Ecotec 1.6L and 1.8L engines), this seal degrades over time due to high heat, constant friction, and engine contaminants, leading to oil leaks, belt contamination, and potential engine damage.
The VAP Auto Parts Front Crankshaft Oil Seal (Part No: 20031720B) is the precise, dimensional replacement component. Manufactured in China (VAP is an aftermarket supplier), this seal is designed to meet the necessary OE dimensions and material requirements for reliable performance, even under the high thermal loads of the Egyptian climate.
THE CORE SPECS: Precision Lip Seal for Opel Ecotec
This seal is a high-precision component typically made of synthetic rubber or FKM (Viton) for maximum thermal and chemical resistance.
| Specification | Detail | Direct Benefit to the Egyptian Driver |
| VAP Auto Parts No. | 20031720B | OE Replacement. Use this code to confirm the specific Front Crankshaft Seal required for your Opel Ecotec engine. |

WHY VAP 20031720B IS YOUR MUST-BUY NOW
You are buying a critical engine component where a minor part prevents a major, costly disaster.
Stops Major Oil Leaks: This seal is designed for continuous rotation and pressure. Replacing a worn seal immediately stops oil leakage from the front of the engine.
Protects the Timing Belt: Leaking oil can saturate a rubber timing belt (on applicable models), causing the belt material to degrade and snap, leading to catastrophic engine damage. New seal installation is mandatory during timing belt service.
Heat and Friction Resistance: The synthetic rubber compound is chosen for its ability to maintain its sealing lip tension and integrity under the high temperatures of the engine bay, ensuring durability in the local climate.
OE Precision for Perfect Seal: The seal's inner diameter, outer diameter, and depth must be precise. This VAP seal guarantees the correct dimensions for a reliable, long-lasting seal against the crankshaft and engine housing.
SECURE YOUR ENGINE’S OIL INTEGRITY.
Crankshaft seal replacement is complex and requires specialized tools and timing component removal. Use only during a service appointment.
Crucial Check: Verify your Opel Astra H/J or Vectra C 1.6L/1.8L engine uses the Front Crankshaft Oil Seal compatible with the 20031720B part number.
