Review on ACDelco 12612350 Original Equipment Gasket by Michael Cleveland

Obvious signs of failure of intake manifold sealing ring began ie flickering pressure needle, never dropped below 40 but definitely needed immediate attention. The OD of the old oil inlet o-ring is flattened out after 149000 (not bad) used this oil pan gasket (12612350) with the FelPro part (72401), be sure to use the RTV in the four corners of the block and the Tighten bolts to specification. No issues with fit, functionality or leaks.
