These engines are notorious for dropping valve seats. These seats break into small pieces and get stuck in the intake manifold. If you do not address this issue these pieces will recycle into the new engine causing it to fail. Tri Star highly recommends that you replace the intake manifold. If you are not able to replace it, the intake must be thoroughly cleaned.
***DEBRIS CAUSED BY IMPROPER CLEANING OF THE INTAKE IS NOT COVERED UNDER WARRANTY***

OTHER UPGRADES/BENEFITS:

• Graphite coated hypereutectic pistons resist scuffing and damage to heat much better than factory aluminum pistons
• Fel-Pro® rear main seals protect against heat and leaks
• Connecting rods are honed (both the little and big ends) to ensure uniformity, and bent rods are scrapped (some competitors will bend rods back into place)
• Chrome plated valve stems resist scuffing and heat for greater durability
  
• Soda blasting  aluminum components provides a visually 'like new' raw material without the risk of contaminating the engine (some competitors blast with other abrasive materials which can become stuck in the engine and cause the new engine to fail)
  
• Every engine is 100% simulation tested very thoroughly by skilled technicians. Engines are checked for good compression, oil pressure, and black light checked for any leaks before packaging
• Engines are provided with a written warranty which clearly outlines coverages. Unlike some competitors, Tri Star warranties are not 'pro-rated' which decrease your coverage over time
• Engines are shipped in plastic totes with simple core return instructions provided to make returning cores extremely simple
• Excellent product support technicians aren't just order takers, they are knowledgeable customer service experts
  
• You're buying your remanufactured Engine direct from the manufacturer so you know you aren't dealing with a middle man for increased costs and headaches for warranty, core returns and technical assistance
