What could cause coolant leak under the body of an 87 190E if the heater core is fine?
There are several areas coolant can leak from. If by "under the body" you mean you see it is under the car but not necessarily right under the engine it could be leaking from a component on the engine then running down the frame before it drops to the ground. Common area for leaks is the water pump. There is a "weep hole" at the bottom of the pump behind the pulley.

1993 with 3.1L Chev Cav with a fast oil leak The leak is on the driver side and is under the device which the air intake hose is hooked to Any ideas on what this could be It is not the valve cover?
It's possibly a seal in the abandoned distributor port. Don't know for sure on a 1993 3.1, but I do know on a 1992 and earlier 3.1 motors, there's a port located directly below the throttle body that was once used for a distributor, before the electronic ignition upgrade was introduced. If you end up doing the seal replacement and your '93 is equipped with a throttle body heater, be sure and replace the coolant hoses going to the throttle body while its convenient. This way you'll avoid a "fast" antifreeze leak in the future as well.
