Do I need to apply sealant under the gasket?

The gasket alone seals the flange face. No additional sealant is required — hand-tighten the bolts evenly and you're sealed. Over-tightening can crush the gasket, so work methodically around the flange.

Will this kit work with my turbo or block setup?

10 AN is the standard drain port for most turbo housings and LS/RB block adapters. Verify your drain port size before ordering — if it's different, this kit won't mate.

Can I reuse the gasket if I remove the flange later?

Replace the gasket every time you break the seal. Oil exposure and bolt cycles compress the gasket permanently, so a new one costs less than a slow leak into your engine bay.
