The Golf R has 10,000 miles now. I was very curious to see how much carbon build up was on the fuel injectors and on the intake valves. Carbon build up is VERY common on Direct Injection Engines GDI/TSI. In this video we will remove the intake manifold, clean and inspect fuel injectors, clean and inspect intake valves and ports. I will also show you 2 ways to clean the intake valves if you do not have a media blaster setup. Cleaning intake valves can be done, you just need to be careful.
