Dear List,
 
I'm doing an engine replacement on my = '86 Vanagon. 
The intake manifold pipes (the four "spider legs") have a
LOT of carbon in them.  = Most is in the bend (center of
pipes) where it's hard to get at. 
 
Any tips on getting this stuff out, = short of a couple
of hours with a little wire = brush?
 
TIA,
 
Steve
