>I'm not sure exactly which bolts you are having a problem with .... and its been quite some while since I have done this task.

The lower intake has two types of bolts holding it down, shorts one that are 6 mm x 1 mm x 32.5 mm, and longer ones, that are 6 mm x 1 mm x ~60 mm. The long ones are located along the "interior" of the manifold, while the shorter ones are around the perimeter. I believe there are three short ones along each of the top two edges of the manifold. There are also four short ones along the edge of the manifold, near the bottom of the head at the front and back of the engine. The one that's stuck is one of those four, right next to the #1 cylinder, behind the power steering pump.

Those bolts are held in by a thread locking compound, probably because the torque is fairly light ~10 ft-lbs.

Prior to my first attempt I could see coolant building up along the top edge of the lower manifold gasket, between cylinder's four & five, so I know that I have a leak there at a minimum. I also noted oil and coolant on the manifold bolts that I removed from that area, and none on bolts from the other side of the manifold. However, what's there will be revealed tonight when I get that last bolt out.
