When checking my expansion tank I seem to have a lot of copper coloured flecks in the water ...I have no ideas where their from, I dont seem to have any probs with the cooling/engine Its a new engine any ideas???

thanks

 

I think the only copper conponents in the engine are the turbo bearings and the Big and mains!
Not sure how any bits of them would get into the coolant system, are you sure its not Rust?

 

well it floats and its shiney almost like metalflake paint the turbo is water cooled but its a garret ball bearing turbo i just dont know it dont leak,it dont overheat/Knock noise from turbo....nothing I have seen leak stopper that has shiney bits in it but we have never used it as its a new motor.
any one else had the same or similer???

 

Could be that the previous owner had a leaky radiator and put K-seal in there as a short term fix?
