Oil Breather Gasket - Type 4 Engines

This replacement square oil breather gasket is designed for Volkswagen Type 4 air-cooled engines in 1700cc, 1800cc, and 2000cc form, as fitted to Baywindow Buses. The gasket sits between the oil breather housing and the engine case, forming an essential seal that prevents oil leaks and crankcase pressure loss.

Over time, the original breather gasket can harden, shrink, or split due to heat and age, leading to oil seepage around the breather assembly and excessive oil mist in the engine bay. Replacing this gasket during routine maintenance, oil breather servicing, or engine rebuilds is vital to maintaining correct crankcase ventilation and a clean, leak-free engine.

Manufactured as a good quality replacement, this square gasket is correctly shaped to match the original breather housing, ensuring reliable sealing and straightforward installation.
