Take it from a boat guy. Don't be afraid of water, my boat engines suck in water every time they get dunked. Old fuel in the block will cause more damage than water.

When I first got into nitro it was all about taking EVERYTHING apart and figuring how it went back together. That's what makes a hobby like this so much fun.

Here is quick summary of what I do when I take in a used engine.

1. I tear the engine completely apart
2. clean, inspect (& measure, if you you plan on making changes in the future)
3. wash with a mildly agressive cleaner (Simple Green is a good example)
4. wash with water to flush cleaner out of all the corners & blind holes
5. wash with alcohol (to remove water) and place parts on a lint-free/dust free surface.
6. re-assamble using a mix of STP engine treatment and WD-40

Every used engine I rebuild gets new bearings and the famous blow test to check the block Y P/S seal after assembly.

if you want more info you can e-mail me ([email protected]) & I'll answer specific questions for you.

PS I'm just blowing it out then using a brush and methylated spirits on the greasy bits
I found some simple green concentrate in a Mitre10 hardware store here in Oz. It really does work very well, and dont know of any other products that are the same here
