Frequently Asked Questions

Q: What is the correct torque for Toyota drain plugs with this gasket?
A: Toyota specifies 37–44 Nm for most engine oil drain plugs using the M12 thread. Always verify against your specific model’s workshop manual (Toyota TIS).

Q: Does this fit Lexus models?
A: Many Lexus models share Toyota engine platforms and use the same 90430-12031 drain plug gasket. Verify the drain plug thread size (M12) on your specific Lexus model before ordering.

Q: Can I reuse this gasket?
A: No. This is a single-use crush gasket. Once compressed, it has permanently deformed to the sump face profile. Reusing it risks an incomplete seal and oil leakage.
