If you warmed up the engine with the radiator cap removed there will be no pressure. The pressure in a cooling system is from the coolant expanding from heat, once it gets to temperature it stops expanding because the coolant is not getting hotter. If you dont get pressure after starting the engine from cold with the radiator cap installed, it could be a weak cap, it is cheap and easy to replace. If you still do not get much pressure, I would suspect more air in the cooling system since air compresses and liquid does not.
As for your oil leak, I would pull your timing covers, upper and lower, and check to see where they are coming from. With all the belts and wind in that area, it could blow oil around. Clean everything off best you can, then run the engine to check for leaks, you can check the water pump, crankshaft seal, and cam seal with the covers off, also check timing belt condition.
