An oil leak in your head gasket can eventually lead to a blown gasket and expensive repairs for your vehicle. When you notice the leak, it is best to seal it up with an engine block sealer before any further damage occurs. These sealers contain sodium silicate, which turns into glass as it dries in the head gasket crack. This is not a long term fix, but can be effective until you can get the gasket leak repaired by a professional.
Step 1
Empty the vehicles anti-freeze from the radiator. It cant mix with the sealer because the two chemicals can react with one another. Open the petcock on the base of the radiator to drain the anti-freeze into a pan.
Step 2
Safely dispose of the anti-freeze according to the EPA rules. Check with a qualified mechanic if you are unsure how to do this.
Step 3
Mix the sealant with water as instructed in the products directions. Each sealant varies slightly but usually involves mixing with water. Pour the mixture down the vehicles radiator opening. Wait for the vehicle to idle for 30 minutes while the mixture lodges in the cracks.
Step 4
Remove the block sealer into a pan by releasing the petcock lever. Pour in new anti-freeze.
Ask a mechanic to inspect your vehicles head gasket when you are able and ready to put money into repairs.
