Intake Valve Cleaning

The Cause 

With all the new advancements in tecnogoy vehicles are improving in torque, power, and better fuel economy but there are setbacks. For instance direct injection is far superior over port injection by directly injecting fuel into the cylinders, but at a cost. The main issue results from the fact that there’s no fuel passing behind the intake valve causing it to get an oil and carbon build up over time. It’s been found that the intake valves are gumming up as early as 55,000km.

The Resolution

There’s only one effective way to remove carbon and oil deposits on the intake valves. The intake plenum first must be removed to blast the top on the intake valves with walnut shells. The shells are safe and don’t harm or groove the valves. This restoration service leaves the valves practically new. The smell of burning walnuts marks another service completed.
