Chevrolet Silverado 2500 Rear Main Seal Replacement Cost
Know what price you should pay to get your vehicle fixed.
How does the rear main seal work?
The crankshaft protrudes slightly from the rear of the engine block so that it can connect to the transmission. The rear main seal covers the end of the crankshaft to keep the oil inside the engine.
What are the symptoms related to a bad rear main seal?
When the rear main seal fails, you may see an oil stain on the ground where the vehicle is parked. The leak will appear to be coming from between the engine and the transmission, but over time it can coat the underside of the car near the engine. In extreme cases, the leaking oil will coat the flywheel, and can cause clutch slippage in vehicles with a manual transmission.
Can I drive with a rear main seal problem?
A bad rear main seal will typically leak oil. You can drive the car in this situation, but you'll need to check the oil and top it off more often.
Any oil leak, including a bad rear main seal, should be fixed, though, as it increases the risk of damaging the engine due to a low oil level. Damage to timing chain tensioners, camshaft bearings, crankshaft bearings and other lubricated components can be expensive to repair.
How often do rear main seals need to be replaced?
The lifespan of the rear main seal varies greatly, depending on the vehicle and driving conditions. The seal doesn't wear like a tire or a ball joint, but eventually the gasket's rubber will degrade. Due to its location, it can easily go unnoticed.
