The oil filter housing is a critical component for your vehicle’s performance.

A clogged crankcase ventilation valve on a Pentastar v6 engine is one of the most common causes of knocking. In addition to leaking oil, it can also result in knocks from the valve actuator or the hydraulic lifters. Soot buildup on the intake manifold can interfere with the function of the valve actuator, causing the engine to lose power. If you notice this, it’s a sign of a problem with the valve actuator.

There are several other common problems with the 3.6L Pentastar engine. Pentastar v6 problems can be indicative of an engine problem or a larger problem. If your car has experienced any of these issues, don’t hesitate to contact a mechanic for further assistance. It is important to note that this problem doesn’t happen to all Pentastar V6 cars. But if you do notice any of the above symptoms, you can rest assured that it’s likely a part failure.

A class action lawsuit alleges that the automaker hid Pentastar engine problems in order to force customers to pay for repairs. A Pentastar engine replacement can run anywhere from $1,500 to $4,500 or more. Many customers who brought their cars to a mechanic for repairs were given equally-defective replacement parts. If you’ve already had to pay for a Pentastar engine replacement, consider an extended warranty.


The 3.6L Pentastar V6 engine is known to experience a variety of problems, including a check engine light, random misfires, and loss of power. In some cases, the problem may be caused by a clogged radiator or cylinder head, but this is usually covered under a vehicle’s warranty. If this is the case, you’ll need to schedule an appointment for repairs to get the vehicle back on the road.

The primary parts to focus on when it comes to Pentastar v6 repair are the water pump and radiator. FCA uses sand-casting techniques to manufacture the Pentastar V6. If the cylinder head is installed incorrectly, sand deposits will likely remain in the engine. These deposits will prevent the engine from reaching a desired operating temperature. As a result, the engine can overheat and need to be repaired.

The 3.6L Pentastar engine also has problems related to the timing chain. This engine uses four chains instead of a traditional timing belt. Fortunately, these chains have a “silent chain link” design that improves sprocket engagement. They also reduce the engine’s noise, vibration, and harshness. Broken chains can ruin your engine. You should always have the engine checked by an expert.

Another common Pentastar engine repair problem is the rocker arm. While these problems are not the same as those with the cylinder head, they can be expensive. For this reason, it’s best to keep your car under warranty until the time comes to get the problem repaired. Fortunately, FCA has issued a service bulletin for the Pentastar engine, but the part is not a perfect replacement.

If you are experiencing the ticking noise in your 3.6L Pentastar V6, you may have failed rocker arms. This can damage the camshaft, requiring costly repairs.
