I checked my coolant and its low and almost black ...

Im at 50k km, I'll flush it but what do you think happened ?

I checked everywhere for a leaking gasket or traces of oil in the engine bay... didn't find nothing.

The car is pushing 400hp since 2 years and run great as the first miles ...


?

 

Post pics.. Muddy water is usually bad head gasket

 

I don't think I could do a good picture, but to describe better, I could say it looks like green coolant mix with oil and residue but after 50 000 km, how is the coolant suppose to look ?

 

green

 

damn

 

headgasket

 

what can cause that ? ( the head gasket problem )

 

Boost from the turbo-- could have been a boost spike, sustained boost of time, detonation, a bad tune, likely either blew out the gasket between cylinders or an oil and water jacket or lifted the head-- , hitting boost when the car is cold, overheating--any of these or all of them. what kind of boost are you running? Do a compression check. Get it to a shop.

 

I did a flush today.

The coolant was brown/black but if it was oil, would it reflect a rainbowish color ? cause it was brown/flat with no distinction of oil in it.

To my suprise their was a quarter inche of residue in the condenser tank ...

Also, I checked online for blown head gasket problems, and I have none, no leaks, no white smoke, no high temp and the car is running smoooth ...
