This professional strength synthetic stop leak revitalizes these worn seals and gaskets to restore them to like-new performance. This is Bar's Leaks strongest formula ever to stop main seal, valve seals, timing cover seal, cam seals, crankshaft seal, oil pan, valve cover and all other oil leaks.

  • Reinforced with synthetic polymers
  • Safe and easy to use, and works quickly
  • Stop oil burning and blue exhaust smoke
  • One treatment stops all engine oil loss guaranteed
