Valve Cover Side Gasket for Mazda Engines

This precision rocker/valve cover gasket seals the cover to the cylinder head on the left side of Mazda’s alloy cam cover. It keeps engine oil inside and crankcase vapors contained, supporting clean ventilation and stable idle. A tight seal prevents oil mist from reaching belts, alternator, and coil packsβ€”crucial for a dry, reliable engine bay.

Why this part is needed

  • Stops oil leaks around the head cover area.
  • Maintains correct PCV vacuum and emissions performance.
  • Protects spark plug wells and wiring from oil contamination.

How it works

Made from heat‑resistant elastomer, the gasket sits in the cover groove and compresses against the head when bolts are torqued to spec. It flexes with thermal cycles yet holds pressure, preventing seepage during hot and cold starts. Correct torque and clean mating surfaces are key for long service life.

What happens if it’s damaged ⚠️

  • Oil smell, wet edges on the cover, and driveway spots.
  • Smoke from oil dripping onto the exhaust manifold.
  • Misfires from oil in plug tubes; possible rough idle.
  • Accelerated oil consumption and grime buildup.

Tip from the bench: replace during spark plug or coil service. Clean both faces, add a tiny dab of RTV only at timing cover joints, then torque bolts evenly in sequence to low Nm. OE-grade fit restores a dry, quiet, efficient engine .
