I am sure that there are lots of opinions about this, so here we go. My 1.7 ate a valve yesterday on the way home from auto-x school. So, it is rebuild time. My main question is, what, if any difference is there between a 914 motor and bus 72 and up motor? And, is it safe to just have the top end (p&c+heads) done without throwing a rod at 90k miles? Thanks in advance for all your thoughts!!
