Can crank cases rust???
I thought the crank cases were aluminum, but I've got some brown stuff 'growing' on the outside of my crank case: on the top around the glow plug and cooling fins, and on surface where the muffler bolts on (and on the muffler too). Or is this just dirt and stuff that got cooked on there?
I don't want my baby to rust!!! |

It's fuel varnish, it brushes off using a brass-bristled cleaning brush.

Ditto on the varnish. It's nothing to worry about and can be cleaned with a little investment in time.

NO [&:] But the steel crank and steel ball bearings sure can and do rust if stored poorly. After run oil is also known as Marvel Mystery oil.
After a day flying run the engine out of gas and pull the fuel line and restart to clear as much fuel from the engine as possible. A few drops of Marvel Mystery oil down the throat of the carb and flip it several times to disperse it inside the engine and your good until time to fly again. For winter storing be more generous and also add a couple drops in the glow plug hole as well. A well cared for glow engine should last for decades. |

The brown discoloring on the exterior is burnt on NITRO SNOT ( varnish). It cleans right off with a little anifreeze soak and bath.

Awesome! Thanks guys. I'm sure the inside of my engine is GLEAMING as I take very, very good care of it (run it dry, plenty of after run, etc.).
This makes me happy:D |

Run fuel with synthetic oil instead of castor and you won't get varnish.

Yep, castor smells really cool but it can be messy.

RE: Can crank cases rust???
Well the smell (and the protection:)) might be worth a bit of cleaning here and there. What else am I going to do over the winter (if I'm not building a kit that is)?

When aluminum corrodes it leaves a white powdery residue.....
Good Flyin |

I used Dawn Power Dissolver to remove it from a muffler and posted my results here: [link=http://www.rcuniverse.com/forum/fb.asp?m=5929584]Removing Glow Fuel Residue[/link] |

Not all engines can take after run oil. Use it in A YS and you will be replacing parts.
Living in very dry areas I never use the stuff except when I'm rebuilding or working on an engine. Come winter months I do run them out of fuel but my storage time is almost nothing. |
