Preparation Essentials

Before initiating the sealing process with Blue Devil Rear Main Sealer, it is crucial to thoroughly clean the engine’s affected area using a quality degreaser to ensure optimal adhesion and efficacy of the product.

Once the area is prepared, the application of the sealer is straightforward. With the vehicle cool and the engine off, a single bottle of Blue Devil Rear Main Sealer should be added directly into the engine.

After the sealer is applied, the vehicle can be driven as usual. The sealing action can commence within a few hours, although it may take up to two days for the sealer to fully exert its effects.

An 8-ounce bottle is sufficient for treating up to 8 quarts of oil in both gasoline and diesel engines, making it a versatile solution for leak issues.

Application Time Frame

Utilizing Blue Devil Rear Main Sealer involves a direct addition to the engine oil, with the sealing process potentially beginning mere hours after application and reaching full effectiveness within two days. This straightforward method ensures minimal downtime, allowing for routine use of the vehicle almost immediately.

Key points in the application process include:

  • Add the sealer directly into the engine oil, following the recommended dosage based on oil capacity.
  • Operate the vehicle normally to allow the product to circulate and begin the sealing process.
  • The sealing effect can commence within a few hours post-application.
