Drain the oil from the engine while it is hot. Place a pan of at least one-gallon capacity beneath the engine. Loosen all six-cap nuts on the oil strainer cover. Pry the oil strainer cover loose. When most of the oil has drained, remove the oil strainer for cleaning. Clean the oil strainer with every oil change. Use new gaskets and copper washers when installing the strainer to prevent oil leaks. Wipe the area around the strainer following installation. Doing so will aid in the early detection of leaks.
