Several of the bolts go through the water pump and timing cover, and into threads in the block, which are open to the water jacket. Are you sure it's oil? If it's oil on the front of the engine, then check front of intake, the timing cover gasket or fuel pump/gasket areas.

Try taping your dipstick down/closed. Go for said ride and check for the oil leak afterward.

You might take off the fan belt to eliminate the turbulence then start it up cold & at a fast idle see if the leak shows up in the several minutes that you have at your disposal.

or better yet, take off the fan/keep the belt/pump operating & spray some water on the radiator as needed to cool it. A slight mist like several squirts on the drivers side (away from where the oil leak is) will cool more than enough for your needs. EDIT this will buy you an extra bit of time & use cold water.

No wonder that was such a toughie to solve, I've never ran across a pump leaking oil from around the perimeter crimp (maybe it is more common than I had any idea). All good now.

And to add a little tid bit to this oil leak search thread. I found the rear corner of the oil pan gasket (small block) was leaking (and not the rear main seal again) by using my spouse's hair dryer. This should work on other engine oil leaks. Here is what I did:
A. Cut off the top (3 or 4 inches) of a plastic coke bottle to use as an air "funnel". B. taped the funnel made from the coke bottle to the end of hair dryer C. Removed the valve cover oil breather D. Rammed the hair dryer "funnel" into the round rubber gasket used to seal the valve cover oil breather (cap end of the funnel) to make an air-tight seal E. Turned on the hair dryer G. Listened with a hose to my ear, and felt with my fingers, all possible areas where oil might be leaking H. Found air blowing/escaping from the oil dipstick tube, but that, of course, would be normal. I. Found air blowing/escaping from the rear corner of the passenger side of the oil pan where the rubber end gasket "tit" had slipped out of place. J. Pulled motor and replaced oil pan gasket and oil pan rubber end seals, making sure this time nothing slipped out of place (my "mechanic" nephew had recently replaced the rear main seal and oil pan gasket without removing the motor, thus the end seal had slipped out of place during his reassembly).

My bad. Jumped the gun. Glad you solved the problem. I had same problem years ago. This was my discovery. Put a straight edge on the mounting surface of the fuel pump and on the part of the timing case cover where the fuel pump is mounted. Might not be straight, surface could be rounded or concave, allowing the oil to pass through. Happened to me about ten years ago on my 318. Had oil leaking in that same place. Turned out the mounting surface of the fuel pump was not straight. Got a new fuel pump, checked that for straightness of the mounting part. All checked fine. Never had a leak there again.

Some good suggestions here! Most wouldn't be necessary if it weren't for crappy parts. I don't trust spectre or spectra (sp?) parts anymore.
Facts are stubborn things.
