Hello. from S.Korea looking for some help.
I'm driving a 2017 718 Boxster S. It has about 43k miles on it.
A few days ago, when I was changing engine oil, I noticed oil leaking from some bolt in the engine block.
It's placed at the driver side of the car at the bottom.
I couldn't check if the bolt was loose.
Anyway, I covered the cover and finished changing the engine oil, but I'm asking for help because I think it's right to solve it as soon as possible and run the vehicle.
I'm not sure what kind of part that bolt is.
It looks like a plug when I search some schematics.
Is the plug in the attached picture correct?
If so, what is the torque spec? No matter how much I look for it, it is hard to find the spec.
If anyone knows about that bolt, please reply.
For your information, there was no leakage when changing engine oil a few months ago.
And I found it a few days ago when I was changing the engine after driving the track.
Have a nice day
