Default coolant leak after turbo install

iv taken my car apart like six times now
there is coolant just pouring out of somewhere but i cant tell if its the banjo bolts
i even put new washers there granted they are very very slightly thinner then the original but it even leaked with the original washers i think its coming from here anyways i cant exactly see it coming out but when you look underneath
i crawled right under the drip and i got a little burned from the DP but i saw it coming out from under the turbo but couldn't exactly tell since the bracket was in the way but the banjo bolts are in that area but a little higher
some one help?

sorry for long post
cliffs:

swapped turbo td04 for stock one
coolant leak by banjo bolts (i think)
with new and old washers
need help

I had the same problem after my turbo replacement. There are 3 coolant lines going to the turbo. One is directly underneath the turbo aimed straight down--that may be the one that is leaking for you. They all use spring clamps and I had to wiggle them around and adjust them a bit in order to get a good seals.

I could be mistaken. I'd still check those lines and adjust the spring clamps. Mine was spraying a very small stream of coolant, but it was under such pressure that it was actually quite a bit of coolant coming out. I stopped the stream coming out and then it turned into a drip that followed the underside of the coolant line for a few inches until it fell. It was very difficult to spot.

When I had my turbo swapped out it leaked coolant from the top coolant line so I just had to get a worm clamp for it and that fixed it.

when you replaced the washers you were sure to make sure the surfaces on the turbo, washers and bolts was clean right?

The tq specs for the coolant banjo bolts on the turbo are: 22.4 ft-lb

update :
i got new washers there a little bigger same thickness but just bigger maybe 12.5mm washers?
dunno but i think it did the trick coolant isn't pouring out of the bottom of my car but there is a lot of smoke coming out of the area of the turbo and the up pipe im hoping its just all the coolant that has been draining out of the car recently i don't see any leaks from the oil drain
im letting the car cool down now and im gonna wipe as much of the coolant of of **** as i can

Congrats! Make sure to burp your coolant system and top it up with coolant as well. Who knows how much you've lost throughout this.
