- You plan to modify the engine and want more room for error without expensive internal upgrades.
What is the bad year for the 5.7 Hemi?
The "bad" years for the 5.7 Hemi include 2003-2008 due to a known issue with valve seats dropping, which can cause significant engine damage. Additionally, 2011-2012 model years, particularly in Ram trucks, were notorious for the "Hemi tick," often linked to lifter or camshaft problems.
This video explains the common issues with the 5.7L Hemi engine: 58s8020 AutomotiveYouTube · Oct 13, 2022
2003–2008 (Pre-Eagle)
- Valve seat drop: This is the most significant issue for this period, where valve seats could fall out of the aluminum cylinder heads, leading to engine damage. This is due to the different expansion rates of the steel valve seats and aluminum heads.

2009 and later (Eagle)
- Hemi tick: The 2009 "Eagle" Hemi introduced revisions that brought a new problem: an intermittent ticking noise that can indicate worn lifters and camshafts.
- Lifter and camshaft failure: The ticking noise is often a precursor to lifter failure, which can seize and cause the camshaft to wear down. This is a costly repair, often running thousands of dollars.
- Multi-Displacement System (MDS): The MDS system, introduced in 2005, can contribute to engine tick. It deactivates four cylinders during cruising, creating temperature differences that may cause oil flow problems.
- Specific problematic years: While the issue became more widespread in later years, the 2011 and 2012 models are particularly noted for the "Hemi tick".

Other considerations
- Exhaust manifold leaks: This can occur in many model years and may be mistaken for the engine tick. It often sounds like a tick, especially on a cold start, and is caused by broken manifold bolts.
- Transmission issues: Many 5.7L Hemi vehicles have also had issues with their transmissions, which can lead to costly repairs.
