I’m sure many of you know and have heard of the issues that come from Direct Inject engines.
While there are many benefits, there are also some downfalls.
- Positives include better fuel economy, efficient power and tons of headroom if you enjoy modifying your car!
- Negatives are low speed pre-ignition (LSPI) in some models and what we will be addressing here, carbon build-up.
Carbon build-up is when carbon deposits are left on the back of your intake valves.
In a typical port injected car the fuel injectors spray over the intake valves essentially cleaning them of any sort of carbon or debris.
This keeps them clean for thousands and thousands of miles and all but eliminates the need for carbon cleaning.
In a direct injected car, the fuel injectors spray directly into the cylinder head, bypassing the valves and thus never cleaning the back side of the intake valves.
Due to no fuel flowing over the valves, carbon deposit can build up and cause many issues.
In some cases you will notice drive-ability problems, power degradation, miss-fires, cold start issues and more.
It is important that they have done this procedure before as if done wrong, can jeopardize your expensive engine!
Some will ask, how would you clean the back of the valves if they are in the head?
Well there are a few ways, but the most common and the way to do it is via walnut blasting.
Walnut blasting is using a pressurized vacuum style machine used to spray crushed walnut shells over the back of the closed intake valves.
Doing this allows for the walnut media to disrupt the carbon, removing it from the valve and intake chamber.
The benefits are immediately noticeable and the procedure should last thousands of miles.
All vehicles that are Direct Injected without a supplemental port injection will suffer from this issue.
How Often Should this Service be Done on a DIT Engine?
Vehicles that are Direct Inject with a supplemental port injected setup should not need this service or at least not for a long time.
On a standard Direct Inject engine, we recommend performing this service at least every 96,000km.
With hard usage or if you notice drive-ability issues or power loss, it may be worth considering doing it earlier.
Direct injection is the wave of the future, but as with all new technology, there are some by-products which will need to be addressed.
We offer this carbon cleaning service on any BMW N54/55, Subaru DIT and many other brands.
We are also capable of doing Audi, Porsche, Mercedes, Ford, Nissan and more so please reach out for a quote on your specific vehicle!
On many applications we can add an Air Oil Seperator to minimize the affect of carbon build up
