I'm trying to fix a coolant leak coming from above my front turbo. It's dripping from the wastegate housing (I think) at about a drop per minute (see pics). I thought it was the coolant return line as that is right above the wastegate housing. However, I just finished replacing the coolant return line and the O-ring on the supply line and as soon as I refilled the coolant it started right back up at the same flow, even before I did the coolant bleed procedure. I'm at a loss and am seeking guidance from the community.

I'd say you should buy a pressure tester they are not to expensive on Amazon I believe and it will be pretty obvious, especially since you say it leaks as soon as coolant goes it.

That's my plan if I ever get a leak I can't locate.

Thanks for your response and I'll take steps to do a pressure test. What additional information would a pressure test give me besides the confirmation that there is, in fact, a leak?

It will leak more from the leak. It should be pretty easy to find then.

N54MDBL, did you ever find the source of the leak? I'm dealing with something similar.
