    Rocker arm falls off how to tell if it's valve spring or seat

    2005 jeep liberty 3.7 back (last) rocker arm on drives side fell off? Just wanted to know how you can tell if it's a broken valve spring or drop valve seat? I can compress spring and it comes back up. But the valve stem looks like it's lower then the other valve stems? Also wanted to be sure...
