Are you adding engine oil? Lots?

What kind of oil is it?

Depending on how clean your engine is you may want to clean it and then watch it like a hawk for a few days. Removing the engine belly pan and seeing were the drips hit the ground may help you track down the leak.

Check your power steering fluid. You don't want to run low on that. I'd assume you should only add Pentosin Green mineral oil.
