What is the function of the crankshaft front oil seal The crankshaft front oil seal, also known as the front main seal, serves an important function in an engine. Its primary role is to prevent oil leaks from the front end of the crankshaft. The seal is located at the front of the engine, where the crankshaft extends out from the engine block. The crankshaft front oil seal creates a tight seal bet...
