Enclave FWD V6-3.6L (2008)
This is an oil filter that is teardown. The left (1) shows a part removed from a failed engine oil main bearing gallery. The right one (2) is a new seal
removed from a new aftermarket filter. This is what a drainback valve looks like prior to failure.
Conclusion
Repair as necessary to remove filter media/debris from oil galleys and piston squirter sprayer in the cylinder head. Repair and/or replace damaged engine
components as necessary.
GM Powertrain engines require oil filters that can meet the challenges of today oil filtration systems, engine oil pressure requirements (both hot and
cold) and Oil Life Monitoring systems. Improper oil filter usage may result in catastrophic engine damage or failure that is not covered by the GM
Powertrain warranty.
