I'm getting an oil leak from the following bolt that is in the side of the block. Any idea what this bolt is for?



I would prefer to know what it is before I change anything.

Are you certain it's oil and not anti-freeze? Unless they've changed that's a block drain plug... coolant.

Ah...thanks for the help. It must be leaking from above and collecting on that bolt head, then dripping from there.

This rabbit hole keeps getting deeper...

What is the size of that coolant drain bolt? I have to replace mine - are they 3/8 pipe thread?
