So first I am a newly licensed 16 year old car enthusiast and this is my first car with a whopping 280k miles on it and counting seeing as its my daily for school and work, I've replaced the top radiator hose and the radiator and it was good for a while until yesterday i was out with my friends and going through my backroads at 3x the speed of light and I felt it go into limp mode and this afternoon I was under it checking my cv axles that I'm going to be replacing soon and noticed a nontop periodic drip of coolant coming from the oil pan, was wondering if any expiernced i30 t owners know where or how to identify it at the very least, I'm a new car enthusiast and have done some minor things but have no idea how to identify where it's coming from without a little guidance and I don't want to just wing it and start flinging **** off until I see the issue because I atleast have a little respect for the mechanisms that go into cars, help would be appreciated please and thank you again.

 

Probably the water pump seals.
