I just picked up a 2000 Focus wagon with 92K miles. I went to the local junkyard and saw wayyyyyy tooooo many 2000-2007 Focus' in the junkyard. Most had the Dual overhead cam Zetec and I saw only 2 with the SOHC motor. I have a SE wagon with the SOHC motor. Is there anything I should be warned about ? Whay are there so many in the junkyard. What are the death of these motors ? Thanks for your input.
