The sump plug — also called the oil sump screw plug, oil drain plug, or sump drain plug — is the threaded fastener at the base of the oil sump that allows engine oil to be drained during a service. Although a small component, a cross-threaded or stripped sump plug causes an oil leak that can empty the sump and cause catastrophic engine damage. Replacing a damaged plug or its copper or aluminium sealing washer is essential maintenance. CarParts247 stocks sump plugs and crush washers from Febi Bilstein, Elring, and Reinz to suit virtually every engine on the market, including magnetic variants that capture metallic wear debris.
The crush washer should be replaced at every oil change — reusing a deformed washer is the most common cause of sump plug weeping. The plug itself lasts far longer but should be replaced if the hex head is rounded, the thread is damaged, or the plug is magnetic and the magnet has separated.
Sump plugs must be tightened to the manufacturer's torque specification — typically 20 to 35 Nm for passenger cars. Overtightening strips the aluminium sump thread; undertightening allows the plug to vibrate loose. Always use the correct washer for the plug: aluminium washers for aluminium sumps, copper for steel sumps. Fibre washers are generally suitable for either material.
