I just happened to be under the car looking around while recently attempting to replace the front O2 sensor, and noticed a considerable amount of oil on the undercarriage. My first thought was that it was coming from the oil pan, but if you look at the video it seems like it might be coming from elsewhere; plus parts of the oil pan are clean.
Any thoughts on where it might be coming from? I plan to pull the pan and re-apply some sort of gasket maker, but if anyone has any tips for what else I might look at that would be great.

 

Try to clean everything and then regularly check to see where the oil starts to come out.

If you are going to pull the oil pan it could also be a good idea to replace it (it is rusting).

Cheers,

Yeah, replacing it is probably not a bad idea. It's sad, I am only just seeing all this rust. Last year this car was flawless. This is what happens when a tuning shop lets your car sit outside over the winter....pretty sad.
