Review on Enhanced Performance ACDelco Gold PF52 Engine Oil Filter by Robert Smith

This filter is suitable for GM TBI 5.7 (350 cid) truck engines with oil cooler adapter. The filter is horizontal and MUST have a non-return valve to prevent draining. This particular filter will not work, but the Purolator ONE #24011 comes with an anti-drain check valve. Before installation I filled this filter with oil. I don't think this non-return valve filter will pose a long-term problem as long as the recommended drain intervals are followed; I give 4 stars for the lack of a check valve.
