Me I just would run the 240D in the garage all warmed up, attach hose from oil drain pan out beside the car to FUMOTO oil drain valve, turn valve to open posidtion, go lay on couch and turn on the TV and check eyelids for light leaks. The sometime the next day or day after I finsh the job, return to couch for further checking of eyelids for light leaks. I will follow this procedure on the new Magnum in the future as I have installed a FUMOTO drain valve in it also.
