What a difference!
These intake valves were heavily coated with carbon buildup before a walnut blast cleaning. Yes, real walnuts are crushed down and used as a cleaning media!
The second photo shows the results afterwords, which we actually got even cleaner with a solvent soak and another walnut blast cleaning.
What a difference!
Can anybody guess the vehicle make by the intake port design!? 🤔
