Review on ๐Ÿ”ง National Oil Seals 710162: High-Quality Crankshaft Seal for Reliable Engine Performance by Chris Morgan

Revainrating 5 out of 5

Top Brand, Best in Parts

This gasket is 10x better than the junk GM used in my Dad's Lucerne. Oil began to leak heavily. Almost cost us an engine. Anyone with a 3800 Series 3 motor would be better off replacing the Balancer Harmonic Seal immediately. What a shame, GM let the bean counter use a junk seal like they did!

Pros
  • Low swelling in hydrocarbon fluids
Cons
  • Great deal
