On the 1997-2005 Chevrolet Venture 3.4L V6, the 3.4L V6 in the Venture is infamous for lower intake manifold gasket failure. The original gaskets react with Dex-Cool coolant, causing them to erode and leak coolant into the engine oil or externally. This can lead to catastrophic engine damage if coolant mixes with oil.

This issue also affects: Chevrolet Camaro, Chevrolet Equinox, Chevrolet Lumina

Common Symptoms

  • Coolant loss with no visible external leak
  • Milky substance on oil cap or dipstick
  • Overheating
  • White exhaust smoke
  • Sweet smell from exhaust
  • Oil level rising above full mark

How to Fix

Replace the lower intake manifold gaskets with updated Fel-Pro design that resists Dex-Cool degradation. Flush the cooling system and change the oil immediately if coolant contamination is found.

Typical repair cost:$400 - $900
