Default soaking engines in antifreeze

I've seen and heard of soaking nitro engines (disasembled) in automotive anti-freeze to clean them up.

Has anyone actually tried it and what were the results?

I soaked mine in it all nite and it seems no cleaner than before?

i think you have to boil them in antifreeze. also might mention that antifreeze is dangerous so dont reuse the pot you use to boil the engines in.

The antifreeze must be heated. I cleaned two of my engines using an old electric crock pot; heated them overnight. A little brushing under running water and they were bright as new. I now use fuel with synthetic oil to keep them clean of burned oil.

You put it in a crock pot on low, no boiling.

Very effective but you need to remember a couple of things.

1. The fumes are bad.
2. Porcelin is porous, don't ever cook food it again. I used a 5 dollar one that I picked up at a garage sale.
3. The new environmentally friendly antifreeze won't do anything. You need the cheap, plain ole etheleneglycol green stuff.

It works like a champ

OK, add heat. Got that.

Since my first post I've sprayed it with easy off oven cleaner[:@]

It's clean, just discolored almost black now? will the antifreeze bring back the original color?

Nope, the surface has been etched by the caustic stuff in the oven cleaner.

And if you get any inside the carb, into the exhaust, or the bearings, you got "trouble in River City".

There does happen to be a safe sprayon cleaner you can get in grocery stores. And it works in the Kitchen. It's DAWN Power Dissolver. It works and doesn't etch what it contacts. You still don't want to get it into those holes.

Just what Baracuda said, I run A bit more heat though. At one of my old clubs one of the guys bought the 5 buck crock pot and A number of us tried it. Works great. I left mine in for A couple of days and A tooth brush worked to clean off the gunk.

I've never done the crock pot method or an engine, but I did what da_Rock said, "Dawn Power Dissolver" on a muffler and documented it here: [link=http://www.rcuniverse.com/forum/m_5929584/tm.htm]Removing Glow Fuel Residue[/link]

It took a whole 10 minutes and that included taking the pictures and typing the post.

This guy is right! ive done this with great sucess! depending on how dirty your motor is, you can even get 2-3 runs with the antifreese.
BE WARNED!!! THIS PROCESS WILL REMOVE POWDERCOAT!!
Ask me how i know! it worked so well on my O.S. and my TTiger, I gave it a go With my Irvine .46 and took every last bit of that pretty red paint off!![X(]

RCTRAX,

I've done both the heated antifreese and t6he dawn Power disolver. The antifreese does work. The Power disolver works fster and better. You can find it in Walmart. Try it, you won't be dissapointed.

I had one O.S. discolor with Antifreeze, every other engine I’ve done has turned out looking brand spankn’ new. In another forum, I think Tips and Techniques, there was a suggestion to use a polish like Brasso to remove discoloring. Might want to do a search and give it a try to remove the discoloring.

When using antifreeze don't put in any parts that have plastic parts that can be deteriorated by petoleum oil products, such as the YS and OS engines with pumps and regulators.

Also, I've been told that the anti-freeze can harm the glow plug elelment. I've done a couple of engines with good results, but I always removed the glow plug, so I don't know about the element being affected. Remember, the engine will be very hot when you remove it. Don't just stick your hand into the pot. Use tongs or wrap a wire thru the mounting holes that you can use to pull the engine out.

Glow plugs, plastic?? The engines should be stripped, taken apart, bearings removed. This is just to remove the burnt on varnish and oil from the case before A rebuild.

Grey Beard,

Couldn't agree with you more. However, some will plunk all the parts into the soup and come out with broken bits. Also at times you can get an engine that can't be taken apart. You don't want to hear that story. In fact I'm trying to forget it myself.

Do you have a crockpot that large?

If you do, you'll get everything clean all at the same time.

This is what happens. The dirt is removed from the outside of the engine by the antifreeze cleaning procedure and floats around as little black bits of grit. Logic dictates that the dirt is also removed from the inside of the engine and likewise floats around inside the engine. If this stuff is not cleaned out it possibly will get in lodged the bearings, between the piston and sleeve, under the ring etc,etc,

Take the engine apart.
