Can someone tell me what the 3 bolts are for that are in the valley near the spark plugs ? Since the FSM calls for 14 headbolts and those would make 17, I'm confused? thanks to all that reply

By chance are you referring to the bolts that hold the coil pack brackets down?

No, these are the 3 10mm hex hd bolts that look exactly like the other 14 head bolts.there is 1 closer to the front of the engine and the other 2 are toward the rear, down as low as the spark plug holes.I'm not sure if i need to remove these since the FSM does not mention them , thanks
