MAHLE Aftermarket has published essential advice for technicians fitting oil filter inserts OX 379D and OX 370D1.
Gaskets supplied with OX 379D and OX 370D1 are additionally fitted with a spring fixing plate for easier dismantling.
MAHLE say the oil filter insert and gasket must always be replaced during an oil change and adds that getting the correct fit is crucial for preventing leakage and oil loss.
Technicians should ensure that the spring fixing plate is facing upward and is visible in the cover.
Oil leakage at the filter cover can occur if the gasket is installed the wrong way around or the spring fixing plate gets stuck in the thread.
Additionally, MAHLE advice that prior to assembly, gaskets should always be coated with clean oil in order to prevent damage and leakages.
An excessively high tightening torque can also cause oil loss at the filter housing, so it’s crucial to follow the manufacturer’s instructions.
