Hello all.. In need of some info here I have a 2012 Ford edge 3.5L and this past weekend wanted to put some new plugs in the vehicle. So I get everything taken off and when I'm loosening the bolts around the intake manifold I notice a Bolt is lose that I haven't even touched... So I try and tighten it up to see if it will thread in and nothing. It just spins and spins at that point I was hesitant to take the manifold completely off since I've had no issues at all previously. So my question is what can I do for a broken Bolt assuming I can get it out are these sold individually through dealer? Secondly Ive put about 60,000 miles on the car and haven't had any problems so what are the risks I'm looking at as this is my daily driver. And my only vehicle? Any info would be greatly appreciated..
