Today we are taking at look at the fatal flaw of the Gen III 5.7L Hemi V8, which is dropping valve seats. This issue was found in many of the 2003-2008 Hemis (pre-Eagle Hemi), engines under the hood of 9 different vehicles and many generations. This was an extremely popular engine, found in 9 different vehicles, and chosen on over 45% of cars and trucks where it was an option. It was also built at a profit, making it a financial success. But we’re not here today to talk about the success of the 5.7 Hemi, but rather the fatal flaw that has killed so many engines. This recently affected my Dodge Charger with the 5.7, so I decided to research the issue and look into it further, and shed some light on this issue, especially if you are considering buy a used vehicle that has this Hemi. In this video, we will look at the specs of the engine, and then look at the major issue of premature dropping valve seats, including what it is, what it affects, and how to prevent it from happening.
