Genuine Mazda Oil Filter Housing Gasket • LF02-14-342

Genuine Mazda LF02-14-342 Oil Filter Housing Gasket

Replacement Genuine Mazda oil filter housing gasket for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models fitted with the 1.8L L8-DE or 2.0L LF-VE petrol engine from 2005/2006 to 2015 listed in the compatibility table.

The gasket seals the joint between the engine and the oil filter housing assembly. It prevents pressurised engine oil from escaping while maintaining the intended internal oil passages between the engine block, filter housing and lubrication system.

A reliable seal at the filter housing is essential for retaining engine oil and keeping the surrounding engine components clean and dry.

This listing supplies one Genuine Mazda oil filter housing gasket. One gasket is normally required per oil filter housing installation.

Replacement is recommended whenever the oil filter housing is removed. The original gasket can become compressed, hardened, distorted, damaged or bonded to the sealing surfaces and may not reseal reliably once disturbed.

Possible signs of a failed gasket include oil staining or leakage around the filter housing, a falling engine-oil level, oil contamination on adjoining engine components or an oil smell after the vehicle has been driven.

Compare the gasket profile, oil-passage openings and fixing-hole positions with the removed component before installation. Housing configuration should also be checked where the engine has a replacement housing, oil cooler or modified filtration arrangement.

Other items to consider: When changing this part, you may also want to consider purchasing the oil filter housing, oil filter cartridge, housing mounting bolts, oil-pressure switch or sensor seal, engine oil and replacement oil filter.

Installation notes: Drain the engine oil where required and clean the surrounding area before removing the housing. Prevent dirt or old gasket material from entering the exposed oil passages.

Refill the engine with the correct oil and check carefully for leakage after starting.
