What is a rear main seal?
The simple answer is: A seal that fits around the rear of the crankshaft to prevent oil leakage.
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. The rear main seal is inserted into the back of the block and fits snuggly around the rear of the crankshaft and keeps the engine oil from escaping.
What are the symptoms of a rear main seal leak?
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. In some transmissions, it will actually be the oil leaking out of the front of the transmission. In some manual transmission vehicles, you may also notice some slipping of the clutch, which can occur with a leaking rear main seal.
What causes the rear seal to leak?
The most common cause of rear seal leaks is age and/or high mileage. The seal can also leak due to the vehicle being stored for an extended period of time, or from running the engine low on oil. This causes drying and hardening of the seal leading to shrinking, cracking and tearing of the rear main seal.
What other factors can contribute to a rear main seal leak?
A few things can cause a rear main seal leak to worsen that is not the fault of the seal itself. If the oil level is too high (filled over the full mark) or the PVC (Positive Crankcase Ventilation) system is not functioning correctly, leaks can occur. The PVC system prevents pressure from building up inside the engine and if it fails, the pressure will cause the oil to leak out. It is a good idea to clean or replace the PCV valve regularly to prevent this problem.
Do I need to use Bar’s Leaks Rear Main Seal with every oil change?
Yes, for best results use with every oil change.
How do you replace a rear main seal?
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.
What else can be done to stop a leaking rear seal other than replacement?
Bar’s Leaks Concentrated Rear Main Seal Repair is one of the only products of its kind on the market specifically designed to solve rear seal oil leaking problems. There are special oil additives on the market that are designed to swell the rubber of the rear seal and cause it to expand, thus sealing off the leak. You can also try using thicker weight engine oil, like 50 weight. The thicker oil can fill in the gap between the seal and the crankshaft, and could slow the leak down.
How does Bar’s Leaks Rear Main Seal Repair work?
This product works in two ways to help solve most any seal type leak. 1) The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage. 2) 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.
