Frequently Asked Questions: Maintenance and Troubleshooting

How do I identify a faulty 119515-11310 gasket?

Common signs include visible oil buildup around the valve cover, a burning oil smell during operation, or low oil levels without obvious consumption. If oil is pooling on the cylinder head, it is time for a replacement.

Can I reuse the old gasket?

No. Once a valve cover gasket has been compressed, it loses its elasticity. Reusing it will almost certainly result in recurring leaks.
