I have owned two 1999 Dodge Ram 1500 pickups. One had a 5.9L and one had a 5.2L. Both vehicles experienced a failure of the ventilation servo (switches cold-warm-hot air mix) and both experience cracked heads. All occurrences happened between 90,000 miles and 100,000 miles. As for the cracked heads neither vehicle had ever overheated, and had always actually run fairly cool.

When accelerating engine pings-particulary on hills at higher speeds/second time they suggested it was fuel quality and on last complaint they attempted to decarbonize engine.and suggest using fuel additive at every 3 thousand miles- also stated that this sparkplug knock would not harm engine- garden city dode mi. Was very nice and admitted that this problem has accured on other vehicles. My concern is that this is not how a new engine should perform and will bring problems down the line -especially when warrenty is gone- is this how a new erngine should perform and it seams quite evident that it will shorten the quality and life of the engine- also the knock continues and ive exhausted all available options for fuel. Regardless of the brand and still using recomended octain as scince day one (87)
