EJ251 and EJ252 Subaru Engines - australiancar.reviews
The crankcase for the EJ251 and EJ252 engines had five main bearings and the flywheel housing was cast with the crankcase for increased rigidity. Like other EJ Phase II engines, the crankshaft thrust bearing was positioned at the rear of the crankshaft to reduce the transfer of natural engine frequencies to the transmission and driveline.
