JPJMustang

purchased a Ford Edge from a Friend - 2009 Limited (3.5L) he did not know the background on the vehicle - drove it 100 miles after replacing the valve cover gaskets (has 187K on it now) pulled up to a stoplight on the way home and the car died. Tried to restart - it would crank but not start thought it was the battery - replaced and tried to start again tried to start (hear the starter hitting) but engine does nto turn over like before worried that timing chain broke and bent valves will get towed to the house - what is the easiest way to determined if salvageable? (scope for bent valves - pull cover inspect timing chain) - I would run compression test but wont turn over right now JPJM
