I'm currently on my mission to rebuild a 99 Northstar that was in my Deville. I originally planned to repair what's necessary, but after I got the engine out, I changed my mind. I'm pretty much going to disassemble this engine, replace as much as I can as needed, and put it all back together.
(I know, that cv axle went south.)
The engine has the infamous halfcase leak and the bottom half is basically all oil residue. It pretty much looks like an iron block due to the stuff. As the engine gets disassembled, I want to clean all the residue and make it look like a new engine in the cover of a magazine. The question is: how would one approach this, with the parts all disassembled? (For instance, block exterior and interior, pistons, various accessory components and also the heads) The cleaning method must not mess with the internals and should be safe for all components. What good techniques have y'all used to clean it while rebuilding?
