Troubleshooting & FAQ
How do I confirm this gasket fits my specific Yanmar engine?
Verify your engine model against the list in the "Engine & Model Compatibility" section. It's crucial to also visually compare your old part with the product images, as variations can exist even within the same model series.
What are common signs of a failed valve cover gasket?
Signs include visible oil leaks around the top of the engine, a smell of burning oil, a dirty or oily valve cover, and potentially lower-than-normal engine oil levels. A faulty gasket can allow oil to seep out onto hot engine components.
Is this a direct replacement for Yanmar part 119593-11380?
Yes, this is a direct aftermarket cross-reference for the OEM part 119593-11380, designed to provide the same fit and function.
Do I need to apply sealant (RTV) with this gasket?
Typically, modern gaskets are designed to be installed dry. However, it is best practice to consult your engine's service manual. Some applications may require a small amount of sealant at sharp corners or joints.
Is this the same as a rocker cover gasket?
Yes, the terms "valve cover gasket" and "rocker cover gasket" are used interchangeably and refer to the same part that seals the cover over the valvetrain.
What is the difference between an OEM and an aftermarket part?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
What are the shipping speed and cost?
We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.
What is the warranty and return policy?
Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.
