Storing engines, avoiding the dreaded gummed up.
Hi all,
Have you any advice for me. I have a number of engines that I put away FOR LATER! When I came to look at them they were gummed up. I am able to clean up many of them, some need full refurbishment but what now?
I recall the time I saved a number of small nuts and bolts by leaving them submerged in paraffin/kerosene? When I next looked they were so rusted they were cemented together with rust. I have heard of Marvel Mystery Oil but it doesn't seem to be available here in UK. Recently sorting out my workshop I found a bottle of Marvel Oil for air tools, a few drops are added to the connector before use to preserve tools when an in-line oiler is not fitted. Is this perhaps the same thing as the Marvel Mystery Oil I have seen recommended.
Has anyone any advice for me about how to preserve old or indeed new motors. It is particularly a problem with my glow engines.
Thanks for looking.

RE: Storing engines, avoiding the dreaded gummed up.
I am really surprised you had trouble with Kerosene. I have stored engines for years in kerosene and never had any rust. There is an oil (what kind and type I'm not sure) people have used with good results for long term storage. I'm sure others will chime in here. But again the kerosene thing has me stumped. I figured it was impossible for something to rust submerged in kerosene.

You can coat them with just about any kind of oil from WD-40 to Motor oil, to Cooking oil. Then seal them in a plastic bag.
And don't worry about them gumming up - it's that gum that protects them. Add a little fuel, flip the prop a few times and the gum will be gone.

RE: Storing engines, avoiding the dreaded gummed up.
Hi Tom,
Thanks for the help.
I was just reporting what happened to me. I understand from reading posts elsewhere and long ago in RCU that many fuels are hygroscopic (draw in moisture) and that the products of combustion in the motor are corrosive.
I just realised that maybe I used the wrong translation from English/English to American/English. I seem to recall recall that people who ask for Petrol in their car are looked at as if they are mad. What they actually want is Gasoline. Maybe Paraffin is known as Petrol in USA?
Ignoring my difficulties over translation I still have some glow motors that have too much corrosion especially in the races to be simply cleaned, they need new bearings.
Thanks for the help.

Sorry to hear of your corrosion problems.[
] I know I was not much help. I have heard of people doing what minnflyer suggested. I'm sure more suggestions are on the way. Also try the archives. I know this is a pretty popular discussion/problem.

RE: Storing engines, avoiding the dreaded gummed up.
I have had NO corrosion or rust problems since using storage fogging oil from outboard motor dealers several years ago. Before that I replaced bearings in 3 0f my 4 strokes. The one I use is from OMC (evinrude, Johnson). I understand it is also available at mercury. it comes in a pressure can and costs about 7 bucks USA. I also use it as an after run oil. I modify the tip to fit fuel line. In 2 strokes you can shoot some in the carb and turn over engine several times. Hope you can find it there, search google for "storage fogging oil Britain".

RE: Storing engines, avoiding the dreaded gummed up.
I use the Marvel air tool oil as an after run oil. ATF (automatic transmission fluid) is very similar, would be a cheaper price for quanity in the storage aspect.
