Keeping Carbon Buildup from Occurring: Best ways to keep clean

Keeping Carbon Buildup from Occurring: Best ways to keep clean

As we read in Direct Injection Problems?, direct injection and crankcase vapors can lead to problematic carbon build-up. This build-up can cause a loss of horsepower, poor gas mileage, and if pieces break off, catastrophic engine damage. In the last blog, I showed you a great way to remove the build-up; but what about keeping it from occurring at all? Well, I will go over two methods that will keep your engine intake track sparkling clean and carbon free, as well as allowing your engine to run in tip top shape. Remember, prevention is better than a solution!

 

Dirty Valve

Water methanol injection has long been thought of as a method for reducing intake temperatures in order to run more timing and boost; therefore adding more power. What if I told you that not only could you use water or water/meth injection for its horsepower supporting benefits, but it could also be used to keep your valves clean? Turns out, with most of the water meth kits we have installed on direct-injected vehicles, an unintended benefit has been cleaner valves and lower carbon build up. Why? Well, the most logical explanation has to do with the cleaning power of water when turned into a hot vapor. Much like steam cleaning can remove grime and dirt from tough places, steam will remove the caked up carbon deposits. How much do you need to clean the valves? To reap the benefits, only a small amount is needed. In fact, less than you would need to support horsepower gain. A cheap, undersized kit that is activated either by throttle position or boost is all you need to keep you car carbon free.

An improved crankcase ventilation system can also help to keep your valves clean by never letting the oil/air vapors from condensing on the valves in the first place. A properly designed catch can system can route the vapors away from the intake track, or at the very least, give more time for the air and oil to separate. Designing a catch can system is not a simple endeavor; however, so be careful when buying universal cans that may not have proper fitment. A lot of thought goes into properly integrating a catch can system into your car. Damage can occur if not designed effectively. A proper catch-can setup as well as different types of setups will be a topic for a later blog post. For now, check out these examples of systems we have done in the past.
