How to clean engine?

[Mark McQuaide]

Does anyone have advice on engine cleaning (the outside of the engine). My
OS 60 is getting gunk on the outside and I don't want to create cooling
problems.

I use to strip motors like that completely down and boil the engine just in
boiling water. If you use a soap as it is boiling it will tarnish the engine
housing to a dark gray. However even with the heat of the boiling water it
will still tarnish it but not as bad. You will see the old gunk floating to
the top. Make sure you use an old pot when you do this cause I know the
wife/mom will not appreciate you clean engine. The next thing would be to
polish the engine to bring out the shin. This can be done with a grinder
with a polishing wheel and jewelers rouge.
Happy Landings!

Try it with the same fuel you use in it! Mostly is works.

With kind regards,

Dave Brown's foaming engine cleaner is highly rated....I haven't tried it
yet, though.

The quickest and easiest is Z-Best. But it smells potent. I use 3M's Safest
Stripper, pint and varnish remover. It is safe and doesn't harm the aluminum,
but it takes two to three coats an hour or two apart and some scrubbing with
toothbrush or Scotch Brite between coats to remove the gunge after it is
loosened. It will look like new. Takes off carbon inside the head on diesels
also.

I just use my dremel tool with the fine wire brush attachment. It
doesn't seem to hurt the metal at all.

I put engines in a crock pot and fill with Prestone antifreeze to cover
engines. Let it simmer on high for about an hour or two. The only other
work may be light bristle brush work-no wire type needed. Engines come
out like factory magic. I remove carb "o" ring as a precaution. When
done, just empty antifreeze out thru carb and exhaust. No need to
disassemble. Engine is now ready to run.

Would you do this on an engine that has nose dived 4 inches into the
ground?

Depth of ground penetration doesn't matter much and you may also
consider throwing your little shovel into the pot!

[kttiger]

Okay, buy what I meant was.

I smashed a ST 45 and when I was done there was dirt inside the
cylinder. If you are using antifreeze in a crock pot and you don't have
to disassemble it then how does the dirt get out on the cylinder?? Do
you only remove the glow plug or do you take off the carb and muffler or
what??

If you had dirt inside the cylinder you would have to take off at least the
head and back plate. Actually, to get dirt clear into the cylinder the engine
would have had to turn over at least once with the dirt in the works, so it
might be ruined. Good Luck!!

For sure you have to dismantle THAT engine.
The antifreeze is meant to solve the brown/black residuals (usually
from castor) on the surface, nothing else.
