cleaning an intake

[Darrell N.]

Mathieu:

Just take it to your local engine rebuilder and have them run it through 
their hot tank cleaner.  It will remove all the paint, grease, rust, etc, and 
look like brand new.  Shouldn't cost you more than a few bux.  You 
won't even need to sandblast it.  I wouldn't recommend sandblasting it 
anyway.  

Don't try this at home, kids, them nasty chemicals can remove a large 
quantity of skin before you even know it.  Not to mention your lung 
tissue and a few brain cells.  Leave it to the Pro's.
