I was at a local junkyard today and seen some really nice vehicles i was wondering has anyone bought one of the engines and tried to flush the stuff out and been successful. I was talking to some one there who bought one of those clunker engines said he flushed it out and put fresh oil and engine ran great he was actually getting another engine. I just wanted to know if anyone else has had luck was going to get a 97 Blazer engine that i seen with only 52000 miles and give it a shot see if it would work if not i have 30 days to return and get another engine. anyways just rying to find any info.
