The cleaner I buy costs less than a gallon of antifreeze and lasts long enough to do many engines. Let's see, you said you can by Cheveron cleaner "nowhere". I live in Bremerton, WA and we don't have a hobby shop locally but I seem to be able to get it. How?? It's called mail order. I just call Sheldon's on the toll free number and order it and give him my Visa number. Not real difficult. Oh and it doesn't come in a can.

Another plus. Cheveron works FAST. I don't have to wait forever while antifreeze does the job. 15 minutes usually does the job.

Well, I just finished the experiment. Bought a 9 dollar crock pot yesterday and tried your method for cleaning an engine. Put a reasonably nice condition McCoy 35 Redhead in the pot with a quart of anti freeze. It had a lot of hardened castor all over it and some black goo cooked on the head. Thank God I didn't use one of my good engines or expensive collector items. Take a good look at the pictures. The aluminum parts are now a grey color. Used to be nice and shiney silvery color. The red paint on the head is GONE. What used to be an old engine with some collector value is now just another runner.

You use your crock pot, I'll use my "dedicated engine cleaner".

I'm going to clean the crock pot and use it for what it was designed for. FOOD.
