I have 98 Big Boss 500 6X6. I can't find the oil drain plug on engine. I have change the engine oil and filter empting the oil tank. I have read that there is still a cup of oil in the crankcase. I have a manual but it looks different than my machine. Anybody have a idea or a picture would be great. Thanks John

It should be near the dip stick but on the bottom side. It can at first appear to be a bolt attaching the engine to the frame if it is dirty on the underside.
