  • Timing Cover Seal
  • Timing Chain Cover Seal
  • Seals the Crankshaft Snout at the Timing Chain Cover
  • Replace Whenever the Camshaft or Timing Set Is Changed
  • Sold Individually

    The front crank seal is already out in the open every time the timing cover comes off, and it costs a fraction of the labour needed to go back in for it later. Fitting a new one alongside a cam or timing set change is the cheapest insurance on the front of the engine.

    Mr. Gasket 18 Timing Chain Cover Seal Features:

    • Seals the crankshaft at the timing chain cover.
    • Should be replaced at the same time as a camshaft change or timing set replacement.
    • Sold individually.
    • Cork/Rubber Material
      Manufactured from high-density cork /rubber blend gasket material. Provides excellent sealing and durability. Non-shrinking and non-sticking, can be reused many times. For OE replacement, high performance street, drag race and oval track.
