Concentrated Rear Main Seal Repair

Typically when a vehicle has an oil-soaked starter, the problem is a slow oil leak in the engine’s rear main seal. Unfortunately, this is a common cumulative effect of heat, age and mileage in older cars and trucks. While it is best to replace an oil-saturated and damaged starter, you also want to offer customers a solution to fix the leak that caused the problem. Quickly and inexpensively solve any oil leaks with Rislone Concentrated Rear Main Seal Repair (P/N 34240). It’s a high-tech blend with reinforced synthetic polymers specifically designed to expand and restore elasticity to renew main seals, as well as cam seals, O-rings, timing cover seals and other gaskets.

Rislone Concentrated Rear Main Seal Repair works with all gasoline and diesel engines using conventional, high mileage and synthetic oil. Simply add one bottle to the engine crankcase at or between oil changes. Most leaks will stop within 150 km or two days of driving. It is available to distribution in case packs of six 500 mL bottles.

Part Number: 34240
Dosage: One bottle treats 4 to 6 liters of oil. Larger systems use 1 bottle for every 5 liters of oil capacity.
Size: 500mL
