Just wanted to double check before jumping to conclusions..

d15b7, 140k on it..

-smokes white like a biiitttcchhh at any rpm
-coolant reservoir steams on startup
-coolant "boils" after warm
-doesn't seem like fans are kickin on (I could be wrong)

 

yeah sounds like the headgasket for sure. Same symptom as mines. change it out and runs good now,

 

z6 swap here we come
