| boiling the engine in antifreeze.
|
Did I say anything about boiling? Low heat, two to three hours, unplug, let cool. The crockpot doesn't BOIL on LOW. You WON'T damage the motor, and it WILL be clean. If you destroyed an engine using antifreeze, you did something completely wrong. If you destroyed FOUR motors in antifreeze, you DEFINITELY don't understand the process.
What exactly happened that you destroyed them?

| The motor still ended up dark
|
Dark isn't destroyed. Not by a longshot. It's dark. That's it.
Prior to the crock pot method, I used an ultrasonic cleaner and a 10 to 1 mix of water and liquid Ajax (an ammonia based household cleanser). Yes, the crankcase darkens, turning a light gray from the original shiny aluminum color. But when you put the motor back together, the darn thing just runs like it used to. That's a process I've used for more than 30 years and on countless engines. I've still got a Supertiger Bluehead 60 that has seen many cleanings since I bought it many many years ago. It's darker than it was, but darn if it still runs fine. If I could find a new ring for it, it would run like new again. Cleaning works.
I could counter by saying I've cleaned quite a few motors that way, and I have yet to kill one. I believe there are a ton of other folk here and elsewhere who have used the crock pot successfully, and there have been few, if any, reports of people killing their motors.

The Dawn Power Dissolver doesn't even turn the aluminum dark. It just removes the gunk. In about 15 minutes.
If the residue in the motor and on the piston is burnt-on castor oil (aka "varnish", soaking the motor in fuel will not remove the varnish).
