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. See similar questions...

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...

Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals. See similar questions...

After time, transmission seals tend to dry out and shrink and internal parts become worn. Bar's Leaks Automatic Transmission Repair reduces rough shifting and friction, while eliminating slip, controlling temperature, and repairing shudder, chatter and whining. Premium high mileage formula restores transmission performance See similar questions...

Bar's Leaks will seal external, internal and coolant to oil leaks. Once installed, the Bar's Leaks particles shrink up to 15 percent. On an external leak, the tiny particles flow to the point of the leak. They then collect at the outside of the seepage and build inward. Internal leaks, the Bars Leaks particles will burn when subjected to the 5000 degree heat of the combustion chamber to seal head gasket seepage and small cracks. See similar questions...

No, you must first drain and flush the entire cooling system, including the overflow tank and refill with water. All antifreeze must be removed from cooling system or clogging could occur. See similar questions...

The truth is, we didn't. As we complete the assembly of an engine, we add a leak detection dye to the oil. After an engine completes it's dyno test we inspect with black light to check for leaks. Only then is all oil, gas and water drained and the engine packed for shipping. If oil leaks are found, the engine never leaves until they are corrected. The major cause of rear seal leakage stems from poor crankcase ventillation. 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...

For most rear wheel drive vehicles the transmission is removed to replace the seal. On front wheel drive vehicles, it is usually easiest to remove the engine to gain access to replacing the seal. Either way, this is an expensive procedure. See similar questions...

Smoking is usually caused by gaps in internal engine parts resulting from excess wear. Smoke Away contains viscosity improvers that thicken the oil film filling these gaps. Smoke Away cushions and coats engine parts helping reduce wear and quiet noisy lifters See similar questions...

After time, engine oil seals tend to dry out and shrink. Bar's Leaks revitalizes these seals and makes them soft and pliable again. See similar questions...

No. Unlike our cooling system product, Bar's Leaks Transmission Repair has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals. 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...

Tip: do not put seals in the dishwasher. To clean them, remove and rinse with hot water, then simply leave to dry naturally. By the way, it often helps to replace the bottle seal, which is available as a spare part from your dealer. 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...
