White smoke

Buddy has a lmm and I noticed when he revved it up the other day it's black then turns white. Injector balance rates are good any ideas

Egr intact?

 

[blue09dmaxx]

Nope

One injector could be bad and is leaking under higher injection pressures and not at idle...

Black is retarded timing, white is advanced timing which is too much.

Black is also lack of air, white is also lack of heat....
