Hey MASOMSMAMA@YAHOO. COM,
Really the only way to find the actual cause of the leak is to visually inspect.
As MMPRINCE4000 said you can use a dye to more easily pinpoint the cause. If the leak area is already too large and it is impossible to find an obvious source cleaning off and running the engine without dye it is generally fairly easy to then find the source of the leak if it is leaking badly.
To begin with what you need to do is using a light and a mirror inspect the motor for the highest source of the leak.
Oil leaks will generally flow towards the back of the engine and down so you are looking for the furthest forward and highest point that is leaking.
If you can post pictures of what you find we can help you identify the most probable cause.
Regards, Joe
