Good Maintenance Practices:

  • Parts should be thoroughly cleaned prior to the application of silicone sealant.
  • Carefully follow the directions for sealant applications as improper use can also cause damage.
  • After exposure to the moisture in the air, the sealant will begin to cure so parts should be positioned quickly after application.

Engine sealants provide an effective solution when you observe small leaks from a variety of engine components. Some of the most common sources of leakage are:

  • Areas around the head gasket
  • Above and below the intake manifold gasket
  • Valve cover access panels
  • Oil pan
