[More Info]
Precision-molded valve cover grommets designed for Big Block Chevrolet and GMC car and truck engines from 1965 through 2005. These grommets seat the valve cover bolts and seals, preventing oil leaks, reducing vibration transfer, and protecting the valve cover bolt holes from wear. Made from oil-resistant elastomer for long-lasting sealing and flexibility, they are an ideal replacement for worn, cracked, or hardened grommets during engine restoration or routine maintenance. Easy to install and engineered to restore proper sealing and fitment for valve covers on classic and late-model Big Block V8 applications.
Features:
  • Fits 1965-2005 Chevrolet and GMC cars & trucks with Big Block V8 engines.
  • Oil-resistant elastomer construction resists heat and hardening for durable sealing.
  • Seals valve cover bolt holes to prevent oil leaks and contamination.
  • Provides cushioning to reduce vibration and protect valve cover threads.
  • Simple drop-in replacement for restoration, maintenance, or leak repair applications.
Installation / Application:
  • Difficulty: 2/5
  • Estimated time: 15-45 minutes
Suggested Tools:
  • Socket set or wrench (appropriate size for valve cover bolts)
  • Torque wrench
  • Screwdriver or soft pry tool
  • Shop rags and solvent for cleaning
  • Small amount of engine oil or silicone grease
Instructions:
  1. Park on a level surface, let the engine cool, and disconnect the negative battery cable if desired for safety.
  2. Remove any components or hoses obstructing access to the valve covers (breather hoses, ignition wires — label wires if removed).
  3. Loosen and remove the valve cover bolts and lift the cover straight off. If gaskets are reused, note their condition and orientation.
  4. Remove the old grommets from the valve cover bolt holes. Use a small screwdriver or pick if needed, being careful not to damage the cover.
  5. Clean the valve cover bolt hole recesses and the mating surface on the head with a solvent and rag. Ensure surfaces are dry and free of debris.
  6. Lightly coat the new grommets with a thin film of engine oil or silicone grease to ease installation and improve sealing.
  7. Press each new grommet fully into the valve cover bolt holes until seated flush. Confirm correct orientation.
  8. If applicable, install a new valve cover gasket or re-seat the original gasket, then position the cover back onto the head.
  9. Install bolts finger-tight, then torque in a crisscross pattern to manufacturer-recommended spec (typical valve cover bolt torque is 7–12 ft-lbs; verify your engine's specification).
  10. Reinstall any removed components, reconnect ignition wires and hoses, reconnect the battery if disconnected, start the engine, and check for leaks after warm-up.
