2000 Chevrolet Blazer

Engine Mechanical problem
2000 Chevy Blazer 6 cyl Two Wheel Drive Automatic

just replaced engine and now that it's all up and running. Just noticed small oil leak from the timing cover seal. Around the harmonic balancer shaft. Shaft was in perfect shape. So assuming I damaged the seal during install but not likely or it was defective. What is best way to replace seal in the timing cover since timing cover on this engine requires removing the engine or dropping the front of pan which is something I would rather not go through. All help would be greatly appreciated. Thanks. Bob
