Fitment advice: Match the engine and application against the compatibility table before ordering. Current catalogue data places a production-date restriction of October 2003 on the MX-5 NB 1.6 application, so later 1.6 cars should not be assumed to use this set without checking the existing components. For imported, modified or previously rebuilt engines, matching the engine family, engine code and relevant component specification before ordering is recommended.

Other items to consider: Engine oil, oil filter, sump drain-plug sealing washer and the appropriate sump sealing compound. If the sump is being removed because of an oil leak, inspect the sump flange and surrounding crankshaft seal areas before reassembly.

Useful tools / consumables: Suitable gasket-removal and surface-cleaning equipment, torque wrench, drain container, fresh engine oil and the correct engine sealing compound where required by the Mazda workshop procedure.

Difficulty guide: Intermediate. Access and sump removal can be more involved than the gasket itself, and careful cleaning and preparation of the sealing surfaces is important for a leak-free repair.

Why BGA? BGA – BG Automotive supplies OE-quality aftermarket engine components designed to provide accurate fit and dependable service. BGA currently supports its full product range with a 5 Year Warranty, subject to the manufacturer's warranty terms.

What's in the box: 1x BGA OK5359 oil sump gasket set.

Installation notes: Remove all traces of old gasket material and sealing compound without damaging the mating surfaces. Check the sump flange for distortion or damage before refitting. Use sealing compound only where specified by the Mazda workshop procedure and follow the correct tightening sequence and fastener specifications during reassembly.
