Your truck's engine can breath or take in air, depending on how it is characterized by the driver. There are two ways for air to be taken into our truck engines; one way is through an air intake system. And, believe it or not, this system also includes the diesel particulate filter (DPF) cleaning process. Now, if you truck has a turbocharger that’s even better because then your truck engine will pull in twice the amount of air! The other way the truck takes in the much needed oxygen is through an exhaust manifold which allows truckers to breathe fresh clean air instead of soot-laden fumes coming out of the diesel engine exhaust stack. When searching for leaks always check the lines and where they split to.
