Default Engine thorough cleaning tips!

Hi, I've got an old engine that's totally gunked and clogged up... I managed to free it up and strip it, but whats the best way to clean it ? I've heard you can soak everything in petrol/gasoline/nitro and then use green wool?

whats your 'best' suggestion?

Thanks!

They are cans of compressed cleaners..Nitro Blast can be found at any Hobby shop, Brake cleaners are at the Auto parts shop..Brake cleaner is cheeper, make sure you buy Non- Chlorinated!!

You may have read about it on other threds, but cooking the engine parts in a crock pot with anti-freeze will cook off the heaviest gunk without hurting the anodizing on the aluminum parts. If the gunk isn't too heavy I'd say strip off all rubber & plasic parts and soak the metal parts in citrus degreaser over night. Citrus is really agressive and will eat through a variety of greases & grimes.

I have did this before and used paint thinner. It will clean it quick. I then clean it with dishsoap and warm water. blow it off with compressed air and lube it with castor oil. This will work very well unless you see any rust or pits in the bearings.
