Does your diesel have High EGTs, Excessive SMOKE, Increased Turbo Lag, and Less Power than it used to? Let’s talk about boost leaks.
Your truck needs air! Not a little bit of air. Your diesel engine needs all the incoming air it can get. Increasing air in the combustion process will help manager your Exhaust Gas Temperatures, Limit your smoke output, and increase your power.
This is why boost leaks kill diesel engines. Boost leaks can result in a smokey, laggy, dog-of-a-truck, which runs hot and burns fuel. Basically, the exact opposite of what you want from your diesel.
Boost leaks commonly occur in boots and clamps throughout the charged air system. That’s anywhere from the turbocharger to the combustion cylinder. Your intercooler system, Exhaust Gas Recirculation components, and even the turbocharger compressor cover can all develop boost leaks over time.
