Grinding, Engine Shavings, Cleaning, Removal

[ekopel]

i know that title doesnt explain anything, but the deal is that as some people may know, I had a bearing go bad in one of my cylinders. I have been working on everything so far, but the bottom end, but heres my question:

I have been shaving and sanding and grinding down parts (cosmetics and performance) and now there is some residual metal shavings all inside the parts. What is the best way to remove these shavings and be sure that I got it all out of my motor. I know some methods, just want to see what you guys think. Its stuck in the residual oil, so im assuming by removing the oil, ill remove the metal.

So you spun a main or rod bearing; your obviously going to have to remove the engine, (I assume thats done) remove the crankshaft out of the bottom end, have your crank repaired or polished and new bearings installed. You potentially have metal fragments throughout all the oil passenges in the engine so the whole block needs to be flushed. Usually a machine shop performs this service but you can flush it by blowing solvent thru the oil passeges in the block and head with compressed air, after disassembling the engine of course.

Done done and done. lol. The rebuild is already underway. I'm waiting on a die grinder and a port/polish kit, and obviously one of the results of that will be a ton of metal shavings. Its mainly the intake parts and such right now though. This was more of a discussion thread than an I need help thread. Many people use different methods, the ones I have used in the past is spray on over cleaner and/or simple green. Both have worked well, but there are some parts that I won't be able to actually touch that I'm going to have to remove metal shavings from (I.E. The inside of the valve cover (under the black metal piece - what is that for anyway?)).

So, for those who care...I found the best answer: Simple Green. Do not dilute it, and only use it on metal parts (I don't know what it would do to rubber, etc), but here are some before and after pics. (the first pic was actually washed down quite a bit already, and the after pic is only with spraying a light simple green on it and letting it sit for 5-10 minutes, then spraying it down with water.

Simple green is a strong alkaline detergent, safe for plastics and rubber if you wash it of after a few minutes and do not "soak" them like overnight.

I use it for engine shampoo all the time.

I used a product called citrus chisel (similar detergent) undiluted in a plastic (PET) water bottle to soak some parts before, the plastic became brittle.
