Oil Seal – Rear Main With Impulse Ring (1.4 1.6) (Volkswagen Polo 9N) is listed as an auto-part option. Confirm fitment, part number and compatibility before purchase, especially where vehicle-specific matching is required.
Oil Seal – Rear Main With Impulse Ring (1.4 1.6) (Volkswagen Polo 9N) is a critical engine component designed for rear main seal position on Volkswagen Polo 9N models with 1.4 and 1.6 litre engines. This seal prevents oil leaks at the crankshaft’s rear end, helping maintain engine oil integrity and preventing contamination and damage due to leaking fluids.
This particular oil seal includes an impulse ring, which interacts with the vehicle’s sensor system for proper monitoring of engine speed or other functions tied to the crankshaft rotation. When replacing your rear main seal, it’s essential to compare the old seal’s position, size, and the presence of an impulse ring to ensure compatibility with your Polo 9N’s engine setup.
The rear main oil seal typically operates in a high-temperature, high-friction environment, making it a key part to check if you notice oil leaks near the transmission bell housing or under the engine. Use this listing to verify it matches your exact engine displacement and model variant, focusing on the rear position and functional features like the impulse ring.
