Solving a rear main seal leak can be a frustrating and complicated experience. Many times the mechanics quotes for getting a rear main seal fixed are so high that it seems a better option to drive the vehicle and just add oil regularly to keep your car running. Driving a vehicle with an oil leak might not seem like it’s that bad of an idea, but it may have some unintended consequences. While you are driving the leaking oil will be getting spread all over the bottom of your vehicle. This includes your suspension components, exhaust pipe and any hoses or wires under your vehicle. Spreading oil over your hot exhaust pipe is most importantly a fire hazard, but also can lead to unpleasant smells and smoke. Also spraying oil on wires and electrical connections can lead to corrosion of the wire casing and cause a bad single at the connector. Lastly, as the oil covers the underside of your vehicle it will allow road dust and grime to stick to anything and everything. As days and weeks go by this grime will turn into a sticky sludge and make any maintenance you have to do on your brakes or suspension components much more difficult costing you time and money.
Just letting a rear main seal leak go is a poor option, even if you don’t intend on keeping your car for very long. Rear main seal leaks usually allow a significant amount of oil to leak out accelerating the problems discussed above. The rear main seal is the seal that goes around your crank shaft at the back of your engine where the transmission connects. Your crankshaft is at the bottom of your engine just above the oil pan so its bearings can be easily lubricated by the oil there. As the engine crank spins it splashes in the oil spreading oil around the inside of your engine making sure it stays lubricated. This also means that the rear main seal is near the oil sitting in the bottom of your engine and gets constantly splashed as the crank turns. This means that even a small break or crack in the rear main seal can allow a significant amount of oil to leak out of your engine. As this oil leaks out it will cause the problems we already talked about but can also allow your engine oil level to get dangerously low very quickly. A low oil level will mean the crank doesn’t splash the oil as well, or possibly even your oil pump running dry.
Since it is such a problem to drive with a rear main seal leak and it seems like an expensive problem to fix it can be tempting to simply park the car, and let it sit or sell it for next to nothing. Either of these options would be unfortunate. Simply parking a car because it has a problem like a rear main seal leak is a waste of resources. No vehicle is every worth nothing, no matter what its condition it is in, but the longer it sits, the harder it can be to sell or fix. Sitting cars can develop other problems like a dead battery, other oil leaks, flat tires and rust. Selling a vehicle with a major problem can also be difficult as you have a very small audience that may be interested in it.
