Troubleshooting & FAQ
What are the signs of a failed collector cover gasket?
Common symptoms of a bad gasket include a rough or unstable idle, audible hissing sounds (indicating a vacuum leak), decreased engine power, and potentially a "check engine" light if the air-fuel mixture is sufficiently affected.
Can I reuse my old gasket?
No. Gaskets are designed for single use. They compress and deform to create a seal and will not provide a reliable seal if reused, leading to potential engine performance issues or damage.
Is sealant required for installation?
Typically, this type of gasket is designed to be installed dry. Applying sealant can interfere with its ability to seal correctly unless explicitly required by your engine’s service manual. Always consult your manual for specific instructions.
How do I confirm this gasket fits my exact Suzuki model?
This gasket fits a wide range of Suzuki DF250-DF350 engines. To be certain, please check the "Engine & Model Compatibility" table on this page and compare the OEM part number (13147-98J00) to the one listed in your engine's parts diagram.
