Wynn's Engine, Diff & Gearbox Stop Leak 375ml- Seal Rejuvenator

Wynn's Engine, Diff and Gearbox Stop Leak is a seal rejuvenator and viscosity index improver. While swelling dry and hardened rubber/ neoprene seals and O-rings to stop oil leaks, the viscosity index improver prevents oil from thinning at high temperatures and seeping past the rings thereby preventing blow-by smoke. This product is excellent for restoring valve stem seals.
