High-quality engine block plug engineered for 1966–1974 Chevrolet Corvette big-block V8s (427 and 454). This precision-machined plug seals the block bore located beneath the mechanical fuel pump to prevent oil leaks and contamination. Built for durability and reliable sealing during routine maintenance, rebuilds, or full restorations, it provides an OEM-style fit and corrosion-resistant finish for long service life and trouble-free installation.
Features:
- Fits 1966-1974 Chevrolet Corvette with 427 and 454 big-block engines.
- Precision-machined steel construction with corrosion-resistant finish for long life.
- Seals the engine block bore under the mechanical fuel pump to prevent oil leaks.
- OEM-style dimensions for correct fit and alignment during rebuilds or repairs.
- Easy replacement — ideal for restoration, maintenance, or leak repair applications.
- Durable, reliable sealing solution to restore factory integrity and prevent contamination.
Installation / Application:
- Difficulty: 2/5
- Estimated time: 15-30 minutes
Instructions:
- Park vehicle on a level surface, set the parking brake, and place wheel chocks. Disconnect the negative battery cable for added safety.
- Raise and support the vehicle securely with a floor jack and jack stands or use a lift to access the underside where the fuel pump mounts to the block.
- Locate the block plug beneath the mechanical fuel pump area. Clean the surrounding area with brake cleaner or degreaser to prevent debris from entering the block.
- Remove the old plug using the appropriate socket and extension. Be prepared for a small amount of oil to escape—have rags ready.
- Clean the plug bore and threads with a rag. Inspect the bore for corrosion or damage and address as needed before installing the new plug.
- Apply a thin layer of thread sealant or wrap PTFE tape on the plug threads if desired for extra sealing. Install the new plug by hand to ensure proper engagement of threads.
- Tighten the plug securely. If a factory torque spec is available, torque to that value; otherwise tighten until snug and leak-free, avoiding over-tightening.
- Lower the vehicle, reconnect the battery, start the engine, and inspect the area for leaks. Re-check after a short test drive and retorque if necessary.
