Did I finally find my coolant leak?!

[brandon91891]

My car has had a slight coolant leak for the past two months I have been slowly adding distilled water to the system, maybe every 100 miles I loose 1 inch of coolant from the reservoir. I looked all the common places the reservoir for cracks secondary water pump etc. with no luck.

Today I was planning to change my driver side turbo hose and I see this on my turbo

This is the only sign of any pink or white oxidization I have found on the car.

This is a picture of my passenger side turbo for comparison



Much cleaner than the other one by the way these are f21s mileage somewhere in the 10,000 range not really sure cause I don't necessarily believe the person I bought the car from after looking through some things they did to this car lol.

Anyways let me know what you think and should this be a major concern what are my options thanks.

Looks like the coolant feed or return on your turbos, or perhaps the coolant pipe seals that are located in the cylinder heads and its leaking onto your turbo hotside and chra

That's on the DS turbo (basically directly below the coolant tank - easily a spill) and it's not much fluid. Get a coolant pressure tester and pressurize the system. The leak should present itself pretty quickly as long as it's not internal.
