Installation Notes
- Ensure the engine is completely cool and disconnect the battery terminals as a safety precaution.
- Thoroughly clean the area around the rocker cover to prevent debris from falling into the engine.
- Carefully remove any components obstructing access to the rocker cover, such as intake pipes or wiring harnesses.
- Unscrew the rocker cover bolts in the sequence specified by your engine's service manual to prevent warping the cover.
- Gently lift the cover off. If it is stuck, tap it lightly with a rubber mallet; do not pry it off with a screwdriver.
- Remove the old gasket and meticulously clean any remaining gasket material or sealant from both the cylinder head and the rocker cover mating surfaces.
- Place the new gasket into the groove on the rocker cover. Ensure it is seated correctly and uniformly.
- Re-install the rocker cover and tighten the bolts finger-tight. Then, torque the bolts to the manufacturer's specified value and sequence using a torque wrench.
- Re-attach all previously removed components and reconnect the battery.
- Start the engine and carefully inspect the perimeter of the rocker cover for any signs of oil leaks.
Troubleshooting & FAQ
How can I confirm this gasket fits my specific Yanmar engine?
Your model should be listed in our "Engine & Model Compatibility" table. Please cross-reference your engine model (e.g., 6LP-DTE, 6LPA-DTZP) with the table. If it's listed, this gasket is a direct fit.
What are common signs of a failed rocker cover gasket?
The most common symptoms include visible oil leaks around the top of the engine, a smell of burning oil from the engine bay, and unexplained low engine oil levels. You may also notice dirt and grime accumulating on the engine cover where oil has seeped out.
When should this gasket be replaced?
The rocker cover gasket should be replaced anytime the valve cover is removed for service (like a valve adjustment) or as soon as a leak is detected. There is no fixed replacement interval; it is replaced on condition.
Is any RTV sealant needed for installation?
While this gasket is typically designed to be installed dry, some engine service manuals recommend applying a small amount of RTV sealant at sharp corners or where engine components meet (e.g., at the timing cover joint). Always consult your specific Yanmar service manual for the correct procedure.
Is this a genuine Yanmar part?
Yes, all available data indicates this is a genuine Yanmar part with the authentic part number 119770-00060, backed by a 6-month warranty.
What happens if I install the gasket incorrectly?
Improper installation can lead to persistent oil leaks, damage to the gasket, or even warping the valve cover if bolts are over-tightened or tightened in the wrong sequence. This can lead to more significant engine problems down the line.
