The term "Hemi" refers to a specific combustion chamber design, not a specific engine. Many different engines have used the Hemi design, and some are interference engines while others are non-interference.
Here's a breakdown:
* Older Hemi Engines (1950s-1970s): These were generally non-interference engines. This means that if a valve fails to close properly, it won't collide with the piston, preventing catastrophic damage.
* Modern Hemi Engines (1990s onwards): Most modern Hemi engines from Chrysler are interference engines. This means that a valve failure can lead to a collision with the piston, resulting in serious damage.
To know for sure, you need to specify the exact engine model and year. You can find this information on your vehicle's VIN (Vehicle Identification Number) or by looking up your engine's specifications online.
Here's how to determine if your specific Hemi engine is interference:
1. Check your owner's manual: This is the most reliable source.
2. Use an online parts catalog: Websites like AutoZone or RockAuto often list engine specifications, including whether it's interference or non-interference.
3. Consult a mechanic: A mechanic familiar with your specific vehicle can provide a definitive answer.
It's important to note that:
* Even if an engine is non-interference, a valve failure can still lead to serious damage. A bent valve can cause engine damage, and a broken valve spring can lead to the valve dropping into the cylinder.
* Regular maintenance is crucial: Maintaining your engine properly can help prevent valve failures and reduce the risk of damage.
