Funola, if my memory is correct, start out my cleaning all of the bits of gunk in the allen socket head screws. Then make sure that the socket tools bottom out and fit properly before applying torque to remove the screws.

You will need either a set of high drive up ramps, or 2 high jack stands. You only need to raise the front end, but you will appreciate some elbow room. A reliable hyraulic jack and a piece of wood is required to raise the engine by the oil pan.

As ACY 76 mentioned, make sure that all screws thread back in by hand before you use any force on them. You don't want to cross thread anything, especially in there.
