More problems, I was driving yesterday and my truck lost ALL power and is smoking heavily. This is a whitish smoke and smells like raw fuel. I just filled up my tank and added one small bottle of lucas additive. My guess is an injector or two are sticking open or maybe a push rod has slipped off but the truck is not really missing, it just smokes bad and will only run about 10 MPH or maybe slower! It seems like I have done nothing but worked on this motor since I installed it. I am getting some air in the fuel lines and have tracked it down to where I need to pull the tank to fix but it was running fine until it started smoking and lost ALL power.
