    How to clean engine before rebuilding?

    Quick question on how to clean the entire engine out before rebuilding it? I have the engine apart and there's some sand and crud stuck in the water passage ways/cylinder jacket on the that caused the engine to overheat and self-destruct.

    What is the best way to remove all the stuff and get it ready for reassembly? Do I just pressure wash the whole engine? I'm kinda hesitant to do this as in my mind, it might cause my engine to rust up and stuff? I want all the water passageways free of debris so cooling system will be 100% working. Any recommendations? Thanks.

    Bottom pics are what I'm trying to get rid of be dealing with. (Note this pic was taken before I completely disassembled the engine - engine is currently completely disassembled - just haven't taken a picture of it to show)

    Lame away. It will not rush if you do it fast. I normally wash it with soap and water, I only use chemical on hard carbon build up. Right after cleaning, I blow dry it a apply some old 2cycle oil on the surface. I will stay rust free for a long long time, just make sure it is completely dry before oiling it.

    Lame away? I just looked it up because I have never heard of it and from what I found out that this is a horse wash product? Is this correct? Or did you mean to say "Lime Away" - the CLR?

    Ok, your saying that I will be fine with just washing EVERYTHING with water and then blow drying them thoroughly and then oiling them right? I just want to know that I got every water passages clean of debris so not to blow the newly built engine.

    Yeah man , lime away. The aluminum will not rust but the sleeve will oil the sleeve after cleaning.

    I used acetone for certain things, soaked bolts in vinegar, soapy water and a toothbrush for other stuff. A toothbrush type scrubber really came in handy to clean in difficult to reach places. stuff came out pretty clean. good luck with the build. michael

    Pop that stuff in a blasting cabinet and go to town. Wash thoroughly afterwards then dry with compressed air, then wipe down the sleeves with some 2 stroke oil on a paper towel.

    Usually a "hot tank" uses an acid mixture that will eat aluminum.
