that’s the coolant line that goes to the turbo from what you just said. It’s pretty hard to get to, try finding someone with small girly hands who can reach in there, take it out and just put a new one in. Of course it’s easy to change when the engine is out, but it’s too much of a hassle to actually pull the engine. Good luck.
my hands are too big to get to the line… i need sasha or someone small to help me haha… i’l going to try to take everything apart and put a new line on. if i cant reach it i dont know, i’ll be shelling out cash to someone who can fix it cuz im just way way too frustrated to deal with this anymore.
