The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage. The seal polymer works by building a polymeric film around the rear main seal and also filling in any groove worn into the crankshaft by the seal.

Because of the Bar's Leaks 2X Action formula, the product has additives to work on any of the three types of rear main seal, no matter the material. See similar questions...

The more in depth answer is: A rear main seal, also known as a main seal or rear main bearing seal is located between the engine and transmission. The crankshaft (the internal engine part that the pistons are connected to) sticks out of the rear of the engine, and the flywheel & transmission bolt to this crankshaft. The engine oil lubricates the crankshaft, pistons and other internal parts of the engine. See similar questions...

Depending on the severity of the leak the first thing you may notice is the oil level going down. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage. While looking under the vehicle around the area where the engine and transmission connect, you will find oil dripping, or a oil residue with dirt caked on this part of the vehicle. Most noticeably under the oil pan and the front of the transmission. See similar questions...

Our A/C Leak Sealer (UVS-1), Stop Leak & Detector (LDS-1), and the leak sealers included in many of our refrigerants seal leaks in rubber components such as O-rings, hoses and gaskets. They work by swelling the rubber in these components to close the holes. Our Maxi Seal (MRL-2) seals both rubber and metal leaks. The metal leak sealer works by reacting with air and condensed moisture outside the system at the site of the leak. See similar questions...
