Chrysler 3.7L V6 PowerTech Engine Problems

3.7 PowerTech valve seat failure

When the intake and exhaust valves are closed, they must be hermetically sealed against the valve seats in the engine head. The valve is considered closed when its head touches the valve seat.

Failure of the valve seat can prevent the valve from shutting all the way, preventing the airtight seal that aids in maintaining cylinder compression. In other words, the loss of compression within the cylinder is the final result.

Low compression renders a cylinder useless because air will seep out when it attempts to compress air. This will have severe effects on performance and, if ignored for too long, may cause additional engine issues.


High temperatures in the engine are the leading cause of valve seat failure in Dodge and Jeep 3.7 PowerTech vehicles. An overheated engine might cause the metal used to make the seat to distort and pop out of its mount.

Try the 3.7-millilitre Magnum Stuck Lifters/Lash Adjusters to change the shape of your eyelashes or get rid of stubborn clumps.

There is only one set of camshafts in the 3.7 Magnum’s engine (SOHC). Overhead cam engines don’t need lifters because the camshaft is housed in the cylinder head.

The 3.7 Magnum, on the other hand, has hydraulic valve lash adjusters in place of conventional lifters.

Unlike conventional lifters, which leave some space between the cam follower and the valve, lash adjusters are installed in the cylinder head and are responsible for eliminating this gap.

There is a common issue with the lash adjusters becoming stuck in the 3.7L Dodge Magnum motor.

Usually, this is due to oil-related difficulties. The lash adjusters can become dislodged if you use oil that is excessively thick or if you neglect to replace the oil for an extended period of time.

When this occurs, the valve becomes trapped in the open or closed position, resulting in significant performance loss and other intermittent engine difficulties.

Chrysler 3.7L V6 PowerTech Engine Reliability

Is the 3.7-litre Magnum dependable? The engine, like its 4.7-litre sibling, has a poor online reputation.

Valve seats and lash adjusters are examples of components that can fail catastrophically and lead to engine failure. Contrary to popular belief, however, these issues are not as rare as they may first appear.

Excessive engine heat is the primary source of 3.7 issues. Maintaining a reliable engine requires taking preventative measures against overheating and excessive engine heat.

Keep up with regular oil changes and coolant flushes, following the owner’s manual, and you should avoid any major breakdowns.

Head gasket and valve cover leaks, as well as water pump failure, are a few other common problems we didn’t list.

All of these issues can be traced back to overheating, making regular preventative checks on the cooling system essential.

We have seen lots of reports of the 3.7 Magnum surviving well into 200,000 miles, even 300,000 miles, but we have also seen reports of engines reporting severe troubles as early as 75,000 miles.

As a whole, these engines should last for at least 200,000 kilometres if cared for properly.

If you’re really worried about damaging your PowerTech, you can beef up your cooling system by replacing elements like the radiator.
