<VV> Cleaning the engine (Teardown III)

[Stephen Upham]

	Well, I spent the morning washing the front housing (even removed the 
bypass valve), alternator adaptor and 90 degree oil filter adaptor 
assembly (taken apart), the Otto deep oil pan and was about to start on 
the top cover.  I washed the parts in HOT soapy (Dawn) water and 
brushed them throughly with a parts brush.  I then sprayed them with 
Purple Power grease remover and brushed them again.  Then I washed and 
brushed them again before drying with shop towels (in every nook, 
crevice, and tube) and then put them individually in front of a 1600 
watt hair dryer for at least 30 minutes each.  I then coated the iron 
pieces with a coat of transmission fluid.
	When I went back down to the garage to begin the top housing, I 
decided to check the front housing.  I used a magnifying glass to 
inspect it.  Everything looked clean.  I then took my index finger and 
rubbed in on the surface of a deep place in the front cover.  I found a 
fleck of what appeared to be bearing debris.  I did it again and found 
two more tiny pieces.  This method is not going to satisfy me.  I've 
already "cleaned" the block halves in this manner, and now, I do not 
trust them to be clean.
	I went back to Richard Finch's book because I remembered him talking 
about cleaning parts before starting to reassemble.  On p.61 of the 8th 
edition, he states to; "Cold-tank clean and glass-bead clean the 
aluminum parts".   I refuse to glass-bead clean any engine parts as 
I've a lot of horror stories of those who have.  But what is 
"cold-tank" cleaning and is this a viable option?
