Bar's Leaks' concentrated rear main seal repair, No. 1040, provides the same unique blend of polymers, lubricity agents, anti-oxidants and conditioners as the original Rear Main Seal Repair in a much smaller bottle: 16.9 oz. vs. 32 oz. According to the company the product restores seal size, flexibility and elasticity. The product also works better than a conventional stop leak on all other oil leaks, including those at the timing cover seal, O-rings and other seals and gaskets.
