So, at first I thought my car was leaking some kind of fluid..I put cardboard underneath for a few days, and there was nothing.

Now this morning it's leaking again. I took her in for an oil change today, and apparently my car has an oil leak. The guy said it's a blowing oil leak, that while I am driving, oil is blowing all over my engine from the wind. Though he said he had no clue where it's from.

She has 163k miles on her. Has anyone else experienced this? I want to know if this is something I can do on my own, or if I am going to have to take her in. Thanks.
