I picked up a complete '91 B400 engine with all ancillary parts for $200 on eBay. It turns and shifts well but has some sludge and badly sealed gaskets. Also looking into the intake ports shows a bit too much rust build up to be comfortable with. Since I (hopefully) won't actually be in need of an engine for many more years, I'm going to tear this one down, make it beautiful, and put it back together. This will be a long term project. Anyone care to chime in with tips, suggestions, warnings, gotchas' or sources for needed parts? (Full gasket kit comes to mind). Thanks in advance.
