What do I use for cleaning engine parts?

I'm rebuilding an engine and was wandering what to use to clean the parts up? I guess its ok to use water on the block since its going to be tanked anyways but what about cleaning out things like the oil pump, pan, and crank? I want to wash all this up very good to insure there are no small shavings that will get into the next motor but I don't want to use something that will get into the oil and cause longterm damage.

Varsol is good for dunking and soaking, and using a brush.

 

Berrymans Carberator Cleaner, is fearsome as a spray cleaner

and it doubles as a way to find vacuum leaks, as it will rev

an engine.

I use diesel fuel. I have a one or two gallon oil changing container with a large lid I use to hold the fuel and small parts. Diesel is not as volatile as gasoline so I don't worry about storing the sealed container in my garage. diesel is also like a very light oil so will offer some lubrication and protection against water.

 

BTW I wouldn't use water on any internal engine parts. I have used a pressure washer on a the outside of a complete engine, but I would worry about surface rust on the internals.

Save your fingers and just take everything you want cleaned up to the machine shop. All the automotive shops I’ve dealt with have a flat rate for cleaning and will not charge you any extra for additional items like the oil pan or crank. I always take my stuff to them on a Friday so they can soak the entire weekend.

 

Just try to get the items as soon as they are removed from the hot tank. Surface rust can develop in just a few hours of exposure to the air.

 

Even aluminum alloy parts such as the front cover and valve cover can also be cleaned at the machine shop. They use a different tank as the standard hot tank chemicals will damage the softer aluminum materials.

i have found that used ATF makes a great parts cleaner, be it a bit thick. to help the consistancy i'll mix it with kerosene or diesel. makes an inexpensive vat-o-cleaner for soaking parts and such.

 

i'm also a bit learly of water on machined parts, or at least water that isn't quickly dried and then the surface coated with a lubricant like WD-40.

MEK, and 111 TriChlorEthane, are just about off the market now

Fearsome cleaners, but rough on the person cleaning, and rough on the environment.

Cleaning with Gasoline is just a good way to blow up your house, and set yourself on fire.
