Rapid Adoption

Gasoline Direct Injection or GDI has seen rapid adoption by the automotive industry over the last several years. This is in lieu of multipoint fuel injection systems which bring advantages in fuel efficiency and reduced emission levels. Although this has been in engines for several years, engine builders are seeing issues caused by these systems as well as many facts and fictions surrounding why these problems exist and how to solve them.

Here are some facts your valve makes contact with the seat, it cools through heat transfer. The water jackets around the seat pull the BTUs out of the valve. These valves are running hot, so when oil droplets come through the intake port and pass through the cylinder head they’ll stick to the backside of the intake valve. That starts to build up layers and it’s not just a layer of ash or goo. It almost turns into something like a lava rock and it will be surrounded with a greasy slime, which traps dirt.

Here are a few ways we can help get the power back in your vehicle and keep the engine running clean

  1. Regular GDI intake system cleaning helps reduce the amount of buildup on the intake and valves as well as cleans ring lands on the pistons.
  2. A hot engine flush will help restore the engine compression by cleaning the rings and pistons on the oil side.
  3. If you have gone too far without the maintenance required we can remove the intake manifold and clean it as well as walnut blast the intake valves from the back side.

What is walnut blasting?

Walnut blasting is a way of cleaning the intake manifold and valves of an engine. Using a high pressure air blast of finely crushed walnut shells (a biodegradable abrasive). Walnut blasting is used to help clear out carbon buildup on older gasoline direct injection (GDI) engines, thus helping the car run better.
