Dorman - Autograde Engine Oil Drain Plug P/N:090-011
The Dorman 568-011 rear expansion plug for the 1968-1971 Jeep CJ5 and other vehicles closes and seals a core opening in the engine.
Over time an expansion plug can corrode, loosen or start to seep, and you may see a wet stain or rust around it. A leak in that spot can also come from a nearby gasket, so trace the source before you replace the plug.
The 1969-1971 Jeep CJ6 and the 1968-1971 Jeep Jeepster are also a direct fit, along with several other Jeep models. The 1968-1971 Jeep CJ5 takes one rear expansion plug.
