WOW!! I can not believe how much rusty stuff is coming out of this engine. This is the first engine I have used that has sat around dry for 12 years. My other cars have always been used, and I never had a problem with either one. Do most guy's acid wash their engines or is this something rare? Do I need to neutralize the engine after rinsing it out, or dose the water take care of that? Anything besides water wetter or anti freeze to slow the rust from getting bad again? Thanks Ed Saniewski
