recently, just had all 8 injectors replaced ( free to me). after i just purchased the truck. Just got the truck back and I am noticing white haze/smoke coming out of the drivers side headlight. It can only be seen at night with the head lights on. As soon as i open the hood you cant see because it is giving more room to escape. There is oily sludge bulid up underneath the engine but oil is full. Havent seen any drips or anything. When i crawled under i noticed there is build up on the power steering pump and looks like my windshield wiper fluid might be leaking a little bit. It DOES NOT SMELL from what i can tell ( the smoke) . I dont know if it did it befroe the injector change or not because it smoked out the tail pipe before. Its not alot of smoke but a haze. Any suggestions on what it could be?
