 Well now that I have my engine and trans out of my Ambo due to the trans
not being able to be shifted I want to clean the engine, fins and
cylinders and get all oxidation stains off and get a uniform finish on
the rough aluminum surfaces/cases and fins. I did try and look on the
topica archives but it told me there are no messages on the loopframe
archives.

Any suggestions on best way to proceed?

Here are some things I dug up in my archive:

ok, bad manners and all hijacking someone elses thread, but
what about an engine that is not stripped down? I'm guessing
elbowgrease and the kitchen scrubby pads?

 For maintaning that 'freshly blasted' look and that 'just
showered' smell on my Ambo, I use Eagle 1 wheel cleaner formula B (I think
it's B), the kind that says Etching on the bottle. Spray it on, wait 15-20
seconds and high pressure hose it off. For stubborn stains I use Scotch
Brite pads or a tooth brush with a small amount of full strength Deck
cleaner (careful around paint) on it. Big word of caution on the etching
wheel cleaner, do not under any circumstances get it on any polished
aluminum or you will be back at it with the buffing wheel and Mother's or
other polishing compound and lots of elbow grease to get the shine back. I
have not had much luck with any preservative measures. I have heard to use
WD40, Armor All and other things after the metal is clean but none seem to
work for me. Just let it oxidize gracefully and do it again.
Good luck,
Rich

I had some luck using simple green to get most of the dirt and greese of
the 70' Ambo that I am rebuilding. I have completely disassembled the
engine. I used (no laughs please)
muratic (pool) acid on the cases. I actually used a resin
thickener used for epoxy and polyester resin with the acid to
turn it into a gel. I painted the cases with the acid and let it set for
approx 15 minutes scrubbing a little with a plastic brush. I rinsed the
acid
 off with baking soda and
water. I then washed the cases with hot soapy water and rinsed with hot
water. I had really good results. The aluminum is really bright. I wanted
to
 know what to seal
the cases with and I think Tom Bowes may have answered my
question with sodium silicate. Of course I don't have any idea what sodium
silicate is or if it is used in any other
type of household product that I may be familiar with. I noticed that I
had
 much better results on the engine case.
The timing gear cover and oil pan really didn't brighten
as well. Probably a different alloy of aluminum.

Jason,

Before you try bead or any other abrasive media blasting give the parts
a wash with Formula 409, and then Eagle One Formula B mag wheel cleaner.
The 409 gets all the grease out of the pores of the aluminum, and the
mag cleaner etches the surface to give it a consistent look. Make sure
you use HOT water for the cleaning and rinsing in order to get maximum
effectiveness. Clean between cylinder and head fins with a thin, round
brass brush. The cases can later be sealed with sodium silicate gel,
thinned to a water-like consistency, applied with a paint brush and
immediately dried back out with a heat gun. I did this on my cases, they
look great and are easily cleaned
