Hey guys, I had some coolant leaking onto my fuel injectors/COP, and I found where it's coming from. I tried tightening it to no avail. I assume I'll just need to replace the gasket or something. I circled (badly squared) where the leak is coming from, I just have NO IDEA what part it is haha. The thermostat is on the other side of it, and it goes around the radiator. Thank you in advance!
