How do you rebuild a 19L engine on a 1995 Mercury Tracer?

The answer cannot be posted on line. Too much information and variables to post here. Purchase a repair manual at most auto parts stores for instructions. You better be skilled before attempting this. This is a job for someone who knows what they are doing, not an amateur. I was forced to rebuild mine when the #4 intake valve cracked and dropped into the cylinder. Yes, you will definitely need the repair manual, a comprehensive set of hand tools, a good torque wrench, a cylinder wall hone, an air compressor, and a means to hoist the engine. Also something else to drive- it took me almost three months to complete. But the job is doable- I have over 110K miles on the rebuild and it is still running strong.
