ABSTRACT:
A method of flushing the crankcase of an internal combustion engine includes the steps of draining the engine crankcase, removing the old filter and cartridge and replacing it with a fitting which consists of a hollow housing mountable on the oil filter mounting means of the engine. The crankcase is filled with flushing liquid and the engine is operated to effect circulation of the flushing fluid in the engine and through the fitting without filtration; the engine is then stopped and the crankcase drained, the fitting removed and replaced with a clean oil filter cartridge and the crankcase filled with clean oil.
