Product Description
CUMMINS 3938157 OEM OIL PICKUP TUBE FLANGE GASKET – 6BT/ISB 5.9L (1989–2002)
The CUMMINS 3938157 OEM oil pickup tube flange gasket seals the oil pickup tube where it mounts to the block on all 1989–2002 5.9L Cummins 6BT and ISB engines. A leaking pickup-tube flange can cause aeration, low oil pressure, and premature engine wear—making this gasket a critical component during any oil pan service or bottom-end overhaul.
This is a genuine OEM Cummins gasket, engineered with the proper sealing density and heat/oil resistance to maintain stable suction under all RPM and temperature conditions. Replace this gasket anytime the pickup tube is removed, or when diagnosing oil pressure stability issues.
