A method and a device for testing the tightness of an engine of the kind having at least one cylinder (1), a piston (2) movable therein and a crankcase (3) with crank means (4, 5), which are drivable by the piston, is based on measuring of the leakage of gases passing the piston into the crankcase by connection of a measuring apparatus (8) so that it communicates with the interior of the crank case. (FIG. 1). |
