Rear Main Oil Seal Leak - Brightlocal News
In the simplest of terms, a rear main seal is a seal used to prevent oil loss from the rear of an engine, where the engine’s crankshaft mounts to the transmission, via a flywheel or flexplate. This, in turn, gives birth to the rear main seal’s nickname as the rear cra… the single most prevalent cause of rear main seal leaks is simple wear and tear. Seals, though relatively hearty, are not designed to last indefinitely.
