OlderThanMe Posted February 14, 2008 Share Posted February 14, 2008 Hey guys, I am looking to get my aluminum block cleaned to a bright surface. I cleaned the top with engine degreaser and toothbrush and then hit it with the pressure washer and ended up with this: I also want to clean the internal parts like the main caps and girdle... Its fairly clean but not clean enough to powdercoat. It was all full of this thick black goo in all of the reinforcement areas. Probably 5 pounds worth. The local machine shop only bakes engines and started blabbing about the EPA and restrictions on hot-tanking. I don't really know of many other ways to clean the thing and don't think baking would help very much. I want to clean the inside of the block too and it is stained pretty dark. You can see all of the areas that were fairly resistant to cleaning. When I cleaned my L26 for powdercoating I just used a media blaster and turned 2003Z's back yard into a black beach... Not that great of an idea. Any input? I'd like to be able to do this myself... Maybe I should just polish the motor to a mirror finish?

Chaparral2f Posted February 15, 2008 Share Posted February 15, 2008 Did you call around to any other machine shops? You might also try automatic transmission repair shops Where I used to work they had a really good power parts washer. Quote Link to comment Share on other sites More sharing options...
