where is the oil pump on my opel astra 1995?

[Tyron]

My car is leaking oil and I think it could be from the oil pump but I'm not really sure where the pump is. If anybody can give me any information about it or even pictures It will be a good help. How easy is it to change an oil pump? the car is a opel astra 1600ie 1995. Thanks

I would get a Chilton or Haynes manual for it. You can also post this at www.cartalk.com as you'll have a much better chance of getting an answer. Most pumps are in the tank but on a car that small it might be in the engine.
