The majority of oil pans that I've dealt with over a lot of years have been quit clean. This has been due to the turbulence created by the rotating mass. The build up of material on the very bottom comes out well with solvents. Lots of lead build up from the days of leaded fuels. Pans with rust inside, or pans from engines that had heavy crankshaft damage. They've been unusable to me. BUT. Now I need to figure out how to get this oil pan acceptable to use. ( As this nice 403 came out of a running 78 Olds wagon. The pans been laying around. ) I need to pull the baffle. Clean. Then braze back in. The lack of extreme cleaning is the reason for rebuilt engine failure. Bob Dunahugh

I'm not happy about not being able to say that the backside of these baffles are 100% PERFECTLY clean for the rebuild of this 403. This 403 oil pan has some rust on the inside. I've just never run into this before. If there is contamination inside the baffles. There's just no way to get it out using normal block cleaning methods. So has anyone removed these baffles for cleaning? Then reinstall. As I've said. I get real anal over cleanliness on engine assembly. When I assemble an engine. My shop that I keep our GMC in. I turn on it's air filtration system 12 hours before assembly. Then do all assembly with paper coveralls, and on white paper. I've never lost a bottom end of any race engines/ driver I've built. This cleanliness just pays off. Bob Dnahugh
