Bar’s Leaks Concentrated Rear Main Seal Repair, now available in a 16.9-ounce bottle, provides a specially formulated blend of polymers, lubricity agents, anti-oxidants and conditioners to stop leaks at the rear main seal while restoring seal size, flexibility and elasticity. Chemical polymers also fill in gaps and grooves in the crankshaft caused by normal engine wear and build a protective film around the seal to prevent leaks.
The product is compatible with all gasoline and diesel engines that use conventional, high-mileage or synthetic motor oil; one bottle treats four to six quarts of oil, while larger systems use one bottle for every five quarts of oil capacity.
