cleaning an intake

[Marteney, Steven J.]

When I rebuilt my TPI, the machine shop hot-tanked the intake and plenum.
They came out nice and two years later still look nice.  I believe he
charged me $10 for the intake and $8 for plenum.

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.
