Truck is not being driven, I am taking it to someone else asap.. what could be issue if coolant id dripping out of the blow by tube? these idiots idea of a test was to block the blowby tube… they then proceeded to tell me that theres coolant in the oil… I cant say for sure if there is or not at this point, all i know is that it was dripping coolant out the blowby tube.. what are the possible causes of this?
