DescriptionThe rear main seal, also known as the crankshaft rear oil seal, is a critical component located at the rear of the engine, where the crankshaft exits the engine block and connects to the transmission. Its primary function is to prevent engine oil from leaking out at this junction, ensuring proper lubrication of internal components and maintaining oil pressure. When the rear main seal begins to fail, several symptoms may become evident. One common indication is the presence of oil leaks at the rear of the engine, often resulting in oil spots or puddles beneath the vehicle. Drivers might also notice a drop in engine oil levels without an apparent cause. In some cases, a faulty seal can lead to clutch contamination in manual transmission vehicles, causing clutch slippage or juddering. If left unaddressed, a leaking rear main seal can lead to significant oil loss, reduced oil pressure, and potential engine damage due to insufficient lubrication.This is an OEM equivelent part.
