Bar's Products 1040 Concentrated Rear Main Seal Repair 16.9 oz

Bar's Leaks Concentrated Rear Main Seal Repair quickly and safely restores worn or dried seals to like-new condition, providing an effective alternative to costly repair bills.

• Specifically designed to seal rear main leaks, but also works on timing cover seals, cam seals, O-rings and other engine oil seals and gaskets
• Most leaks will stop within 100 miles or 2 days of driving
• Easy application: simply add entire bottle to engine crankcase at or between oil changes without overfilling
• 16.9 oz concentrated formula
