What are possible causes for an oil leak? I have a pretty bad oil leak problem, what could it be?

 

Bad seals...bad gaskets. Depends on what exactly is leaking.

 

Lol I love how you're going through the posts I didn't make it to Depends on how bad the leak and where. Is there oil all over the trans and such? Have you checked around the valve covers? Checked your oil drain plug?

There's 5 million different reasons for an oil leak. More info would be nice lol.
