So, I bought a 2nd hand f20 to replace my blown motor. After getting it home, I notice there is a tapped hole just behind and below the oil filter. It's about an inch round and 3 inches above the sump gasket. What the hell would it be for?

 

Possibly a oil return for a turbo set-up? Pics?

 

^ Yeah thats my guess as well.

 

How do I upload pics off an iPhone lol?

 

There's probably an easier way, but I would transfer them to my computer first, upload them from there to imgur, and then link the imgur pages to the post with the add pic button. Kind of cumbersome.
