The rear main seal for your Ford Escape is also known as the rear crankshaft seal. It can be found inside of the rear of the engine, where the crankshaft exits the engine block. The rear main seal is tasked with keeping oil from leaking out through the back of the engine. Rear main seals are made from silicone or rubber, and they may wear down over time. Signs of a faulty or damaged rear main seal could include seeing oil leaking from the transmission or off of the engine oil pan. It's important to address oil leaks, as a significant loss of oil could potentially lead to the engine in your Escape seizing. O'Reilly Auto Parts carries replacement rear main seals and the tools that you need to complete the repairs on your Escape.
