Another caveat. The AF mix in the crockpot will turn some ENYA crankcases and other cast parts dark gray (again, don't ask me how I know). This may be a function of how long you cook the parts, but, overnight overcooked my Enya. It was not damaged but the color was dark.

The parts must be completely submerged or there will be a gray line at the water level
The AF must be kept warm but not boiled.

This is a pretty good thread. Lots of good information in it for people, and the guy with the 80 ends up having a near new engine when he's done. Could end up stronger than new, something I've seen happen many times after cleaning up an abused engine.

RE: This is Bad Right?
ahicks,
Here are a couple of before-and-after pictures showing the effectiveness of the anti-freeze treatment that you described. The gentleman whose hand is holding the engine did a show and tell at a couple of club meetings in 2002 to describe the process.

RE: This is Bad Right?
if the results come out as i expect them to , i will post the finished results.... i wont pr4obably wont be doing the cylinder, the ports are nice and clean
and after a couple of tanks i will post rpm as well.... i tached my motor today with a Xoar 26 3D prop and got 6090, tuned to fly

140 rpm could easily be written off to atmospheric "noise". If you have higher baro pressure than your last tach run you could pick up that much rpm doing nothing. Don't want to dissapoint, but don't want your sights too high either. See what happens in an hour or two of running after the rings and clean up.

oven cleaner does too if you leave it on too long...now i still use it but spray it on, then scrub with toothbrush...then quickly spray it off with rubbing alcohol to get oven cleaner residue off....then repeat the same process a couple of times till the motor looks "like new" condition

I found out cleaning parts is real easy using Lysol Lemon scent cleaner.Its a great degreaser and The wife doesn't get mad cuz it doesn't stink. I shared this with the guys at ************.com and they tried it too! Great way to clean up the chassis of any nitro burner that looks like its covered in grease.

Do not cook the whole engine. Geez guys, gassers have sealed bearings. Some are lifetime greased. If you want to destroy them, toss them into that crock pot. Gotta get past the glow mentality[:@]

I agree witth you entirely, but, just how sealed are the "sealed" bearings? Will the antifreeze get past the seals? Or are there other considerations, like the seal material or the metals involved? Thank you, I am genuinely interested in this issue.
Sincerely,
Richard

Regarding the potential for an engine to come out grey. The engines I cleaned were a mix of Webra, O.S., and Enya, 2 stroke and 4. They all look about the same to me when done. Whatever the color, which I haven't seen as anything unusual, when the results were weighed against what I had going into it, there is no question regarding the benenfits of the process. I did squirt them down pretty good with WD-40 and blew them out with compressed air as part of my process. Maybe that has something to do with the resulting color? Dunno. Based on my experience with 10 or 12 of these to date, I sure wouldn't let the resulting color slow me down any.
Regarding the cooking temp, I'm working in a well ventilated area. The same one I'd be working in with any other chemical (like gasoline for instance). I did boil some stubborn parts for a couple of hours - and it does emit some pretty rancid fumes I wouldn't be sniffing - but the AF process is much more effective that way if you require it to be? Not sure I'd walk away from that process overnight though.... FWIW

RE: This is Bad Right?
It was extablished many years ago that actually boiling in the antifreeze is likely to cause discoloration.
You are supposed to use a 50.50 mix and just keep it around 150 to 170 degrees F and no higher.
I use a pot pourri pot and it never boils the solution. My wife's crockpots will both eventually boil her stew on the lowest setting

I do not know how well the bearing seals would hold uo to hot antifreeze. It's certain they were never intended to be subjected to the chemical compound. However, if anyone wants to give it a try with all the different sealed bearings out there, be my guest.

Ok here is the before.... Im still waiting on the rings...they should be here Tuesday... I went with the general consensus, and will do the antifreeze method.....just need to find a pot pourri pot now
i will post the after as soon as im done

Personally, I'd just check the ring end gaps, clean the ring grooves, put it back together, and run it 32-1 for a few gallons of gas. If the end gaps are good the rest of the piston and cylinder stuff will wash clean over some running time.
Did the previous owner use a tuned pipe on that ngine?

RE: This is Bad Right?
the previous owner was a POS IMO...He didnt give me a straight story. He said his friend gave him the motor, and that the last time he remembers it ran fine. He did that so i couldnt blame him(seller)
this engine has been plagued since i first got it... I found out i had one of the defective hubs,,,the magnet spacing was off(would not idle down properly )...so i had to ship it off and pay to have it replaced...the previous owner also screwed with the carb so i had to buy a new one as well...new rings is the last money i plan on investing in this motor..as long as my rpm is no less than i was getting before...ill consider it a learning experience

I've got the good old stuff,.........The stuff has ruined more than a couple parts in the past, it will remove anodizing and all the hair from your nostrils.

Here are the pics of my piston... it soaked in a potpourri pot overnight, with antifreeze, it did an ok job but not what i wanted.... it turns out i have the "new and improved" safer formula of antifreeze(orange color) that could be why.....so for peace of mind i so i went to the hardware store and purchased a gallon of mineral spirits and soaked my piston and cylinder head overnight....it seamed to get the rest of the carbon off.... i will fire up my motor tomorrow morning, and post rpm numbers after a few tanks, hopefully by this saturday if the weather is nice

3M makes a superfine light deburring wheel, 6 inch diameter, 1/2 inch center hole..Works great for cleanup of surfaces without removing material...Got mine from MSC Supply...Makes pistons look like new.....Takes burrs off sharp corners, rust from tools...Will last a lifetime if used with a little care...Mine gets used every day and often, lasts about year before it's too small.....
