Manual Valve Cleaning

This is from a 2008 Jetta, but carbon buildup is an issue on direct injection engines. This is simply FYI.

I spent my day off from work opening my manifold and manually cleaning my valves. It was a great learning experience and I'm pretty happy with the results. I used GM Top Engine Cleaner to soak the valves, but the best method by far was to scrape with picks and suck with a shop vac. I also found spraying carb cleaner and vacuuming it out worked well, kind of like at the dentist when they spray off your teeth and suck out the water.

After (I admit my patience level waned, but I'm happy):

I'm happy knowing my valves are clean and that I was up to the task. If you asked me to clean your valves I'd tell you I wouldn't get out of bed for anything less than $300.
