also this will help. I did a new thread also. Open drain plug on
engine also.

You can't see the starter or the block plug from the top. They are below the manifolds.

Go underneath, on the passenger side, and find the starter, neatly tucked into the side of the block, below the manifolds and at the very back of the engine.

Now find the very forward end of the starter.

Go three inches further forward and about 1 inch vertically upward and there will be a bright hex plug that sticks out of the block. That's the block plug. It won't be difficult to remove.

I'll look...if you can feel the bracket that goes from the top rear bolt of the mount pedital to the exhaust manifold...then feel the area around 10-11 oclock based on that within a hands width....it will be the only hex head you will leel in the area...you can see it from underneath but not from above.
passenger side...look at the bottom of the photo close on the right side you well see the passenger side motor mount pedistal.....its just behind and obove that. Where the red circle is....which is near the front edge of the starter and just above.
