I believe the lawsuit on the EJ 2.5l engine is not placed properly by the judge and the oiling system does clean out the contamination in the oil. I have been a technician for Subaru for 28 years and know the product very well. Unless the oil pump is in fail safe causing full pressure and it to bypass part of the filter or the filter becomes clogged are the only way contamination can occur. What most likely happened is the customer had a engine replacement and poor workmanship occurred. Improper torque of cam caps or not priming the engine will cause severe damage and a new installed engine will self destruct quickly.
A modified EJ engine will also self destruct quickly.
I have had customers bring in their WRX STI with spun rod bearings. They had green engine coolant in it. Supposed to have super coolant blue by Subaru. Bolts were missing and loose and fuel smelled like E-85.
The ECM also did not have the proper CID number. Modified... Yes customer say it has been modified... No, can I prove it has been modified, yes of course. It's not always the product but the owner. Plus general maintenance as well. Check your oil level.
