- I saw a blurb on Motorweek a while back where a non-invasive
- technique for removing carbon buildup was described. This kind of
- fits into the Popular Mechanics "Gee Whiz" category, so if anyone out
- there has tried it and it worked, let us know:
-
- Basically, the idea is to scrub the insides of the cylinder and head
- with coarsely ground walnut shells. There is some kind of gizmo which
- I guess pumps these walnut shells down the intake side, and swirls
- them around with sufficient energy to remove carbon deposits. The
- advantage, obviously, is you don't have to take the head off. I don't
- know--it might be necessary to remove the intake manifold or
- something...
