oil weeping from intake manifold bolt
i noticed today that one of my intake manifold bolts had some oil residue around it and it looks like oil may have been weeping out ever so slightly. would it do any harm to take that bolt completely out, put some silicon or something on the threads and tighten it back down without undoing the other bolts? i'm not sure how "sensitive" these plastic manifolds are if the bolt pressure is disrupted.
also, i know the torque specs call for 105 in/lbs on the manifold bolts, but when i set my torque wrench to about 8.5 ft/lbs (i did a little math and it turns out 105 in/lbs = 8.7 ft/lbs) it felt like i was going to over tighten them cause they turned even at 8 ft/lbs when i tried that for the hell of it. i cant believe they used little 8mm's on the manifold and i'm afraid of snapping them!
i went over all of them with a small socket and some felt slightly looser than the others with my bare hands. so i kinda went by feel and got them all about the same without the torque wrench.
is that good enough and can i take that one out while leaving the others in?
