i have torn down the engint to a shortblock now and was wondering while the engine is shipped off and im just sitting around... i think i ought to clean out the engine components such as uim, lim, throttly body etc. should i let them sit in a cleaning solution, take a bild wire brush and run up the exhaust tunnels(uim, lim).?

 

This topic is posted at least once a week, so a serach would have turned up all the info.

The best way to clean cast aluminium parts (in my opinion anyway) is to first degrease with a cleaner of your choice (I prefer Castrol Super Clean) and then use a wire bush. If you use a manual brush, one mounted on a drill and a wire wheel mounted on a bench grinder you can get the metal nearly perfect. Then paint or coat with clear.

 

I just saw a show on the Discovery Channel (Modern Marvels?) that detailed dry ice blasting...looked like a great way to clean parts.
No deformation of the surface (they showed blasting an old book cover!) and no residue.

Might be worth checking into.

 

appreciate the info... i knew that everyone asks about painting exterior didnt kno just about cleaning. woulnt a wire brush on the exterior leave lots of scratches? or is it a durable enough paint that it wont affect the finish. i guest a mild wire brush will due the trick

 

dry ice blasting...? sounds a little extreme and i was looking for a cheap way to clean them and a way for myself to due it. a little manual labor always good. ill check into the dry ice thing though

 

they clean the robots and machines at my work with C02 blasting

 

The castings are already very rough, so the wire brush is almost ideal.

If you have access to glass bead blasters, they do a wonderful job as well. Soda blasting works well too.
