T4 Oil Pump - 1.9 Diesel (1X,ABL)

This engine oil pump is designed for Volkswagen T4 models fitted with the 1.9 diesel and 1.9 turbo-diesel engines. The oil pump is responsible for circulating pressurised engine oil to all critical internal components, including crankshaft bearings, camshaft, hydraulic followers (where fitted), and turbocharger on turbo-diesel engines.

Driven mechanically from the engine, the pump draws oil from the sump and forces it through the oil filter and galleries at a controlled pressure. Correct oil pressure is essential for lubrication, cooling, and long engine life. A worn oil pump can result in low oil pressure, noisy operation, accelerated bearing wear, or catastrophic engine failure if left unaddressed.

This pump is manufactured to the correct specification for the listed 1.9 engines and is suitable for both naturally aspirated and turbo-diesel applications where specified. It is ideal for engine rebuilds, oil pressure fault diagnosis, or preventative replacement on high-mileage engines.

During installation, it is recommended to prime the pump with clean engine oil before first start-up and to inspect the oil pickup strainer for contamination. Always use a new gasket or seal where required and follow correct torque procedures.
