Where is the blow off valve located on diesel engines?

On diesel engines, the blow-off valve, often referred to as a wastegate, is typically located on or near the turbocharger. Its primary function is to regulate boost pressure by diverting exhaust gases away from the turbine when the desired boost level is reached. This helps prevent excessive pressure that could damage the engine or turbocharger. In some setups, the blow-off valve may also be found in the intake system to release excess pressure during throttle closure.
