I got this weird thing happening since I installed my turbo. There seems to be a leak of coolant on one of the hose that connects to the turbo. It seems to happen only if I boost. The coolant leaks and then dry on the spot, so I see greenish stains on the banjo bolt. I did tighten the collar on the leaky hose.

First pic we see the wet area caused by the leaking.


Second Picture we see more exactly where the leak comes from. It really between the banjo bolt and the rubber hose.


Third Pics show same as first and second, plus we see where my coolan hoses goes. The one we see from the TB is the one tha leaks on the turbo. and YES I did swapped hoses before posting.

Second hose is plugged beside injector #4.




any Idea of what could make this to leak ? I checked by blowing in one of the hose to see if coolant would comes out of the other, and its positive, so I know they're not clogged (or very clogged)

 

I just don't like banjo bolts. You could use a 90 elbow and a hose barb instead of the banjo bolt. Use teflon tape too! Home depot has some good high temp, oil/coolant resistant teflon.

 

damn

that first picture takes the trophy for "most adapters used in a single oil line"

 

just don't run it water cooled at all. this is why i don't run mine, after all the trouble putting it in, it started leaking. i just stay off boost, driving the speed limit and barely giving it gas for 5 minutes while driving before i park the car.

 

i had the same problem once.
replace the 2 copper washers for the banjo bolt and crank it down.
use 2 hose clamps on each if there is room.
worked for me.

 

Another tip is to use the right size hose clamp so it doesn't oval out.
