How do you replace the rear main seal on a 1995 Chevrolet Caprice?

In: Chevy Caprice Classic [Edit categories]

Answer:

It has been my experience as a repair shop owner for 22 years and a technician for 45 years that I VERY seldom replace rear main seals. Find a shop that is familar with the Positive Crankcase Ventilation System. It requires more than just replacing the PCV valve. The system MUST be drawing in fresh air. If it does then it is relieving the crankcase pressure from the engine. The pressure causes the seal to leak. RELIEVE the pressure and clean the area and see if the leak has stopped. In my time as a technician I have only replaced rear main seals when doing a clutch job or installing a used engine.
