2. Oil Pressure
Oil pressure is a common problem of the Jeep 4.7 engine. Due to this issue, your vehicle engine performance will reduce dramatically. Moreover, the used oil in the engine will become too thick.
The problem arises when the condition of the lid gaskets and the filling plug is terrible. Expanding both materials is inconvenient. As a result, your car oil may become old before the regular schedule. If you are unable to address this issue quickly, more issues may arise over time.
Solution
The first thing you need to do is, change the oil on time. Also, consider using lightweight, high-quality, and synthetic engine oil. Furthermore, use a professional’s assistance to change your car engine oil.
3. Domino Effect of Complications
In order to avoid 4.7 engine problems, the thumb rule is, maintain engine components on the scheduled timeline. Every vehicle user should follow this rule strictly.
At this point, a poor spark plug, damage in any parts of the engine, improper oil changing schedule, and the low water level in the cooling system could be the first thing you need to focus on.
Bad conditions of these components will damage the next system to which they are connected. This means problems in these parts will cause additional flaws.
You can effortlessly detect problems in these parts when you regularly check your car engine.

Excessive noise is a well-known malfunction of the 4.7 engine. It is of utmost concern for some customers, while this is an annoying factor for other users.
It happens when there is a defect in the exhaust seals. This way, when you accelerate, you can listen to a firecracker sound.
In addition, it may also occur when a valve contacts the piston. While this is the case, severe engine failure is the reason for excessive noise. So, the lack of right engine oil and the connection between the valve and piston are the major issues behind noise production.
Although this is not the only reason, you should check it first.
Solution
Before you start using the vehicle, you need to heat the engine, it’s an effective method of solving this issue. But the engine hardly heats up in areas of low temperature.
Proper expansion of the metal occurs when the engine is at an ideal temperature. If it doesn’t happen, the metal generates excessive sound due to the vibration. Moreover, it is necessary to apply internal fluids periodically. But, again, consult with a professional in this case.

Initially, you may notice a small amount of oil leakage. If unaddressed promptly, it will be uncontrollable. Incorrect installation of the oil filter is the prime reason for this trouble. A problem in the engine gasket or crankcase gasket is the root cause as well.
