Diesel Intake System Cleaning & Fuel Pump Repairs

Clear oil-vapour build-up and restore late-model diesel performance.

The most common cause of performance loss in late-model diesel engines is clogging of the intake manifold with oil-vapour build-up. Oil vapours enter through the crankcase breather system and accumulate in the intake, eventually restricting airflow. We recommend a thorough intake clean every 50,000 km to prevent performance degradation.

Symptoms of a contaminated intake system include power loss, poor throttle response, high fuel consumption, hard starting and uneven idling.
