Supporting the other threaders on this subject:

Only saw one engine that had fluctuating oil pressure. It was a Mack bobtail trash truck with about 500k miles. As the engine rotated, the not so worn parts would pass by the very worn parts and as they did the pressure would drop and return for the other part of the cycle. Ticking is low oil pressure in lifters caused probably by worn pistons therein.

Stepping on the gas forces the engine bearings against one worn out side of the respective crank or camshaft leaving a large space on the other side allowing for more oil to excape as compared to when you let off and let the crank/cam center.

My advice; get an engine overhaul. Your truck has earned it.
