01. Oil Leaks Problem
Amongst all the engine problems above, the oil leaks problem is the most common. However, this issue doesn’t relate to any engine design flaw. The older an engine is, the more likely it will leak oil.
Using your car every day slowly weakens everything includes the seals and gaskets of the engine. The rubbery gasket hardens and cracks over time.
Within these cracks, oil continuously leaks either when the engine is running or when parked. Oil usually seeps out from various gaskets located behind and in front of the car engine. It also leaks along the sides of the gasket of the oil pan.
Although several gaskets may leak oil, the most problematic of the oil leaks is the one from the gasket of the valve cover. This particular gasket undergoes severe temperature and pressure conditions over time.
Therefore, the gasket of the valve cover is the most likely gasket to leak oil on a Nissan 3.3 engine as the car ages.

02. Timing Belt Issue
The timing belt issue is a common problem for many car engines. However, this problem usually amplifies as a car engine ages. Since most Nissan 3.3 engines are old, there is naturally a greater tendency for the timing belt to fail while the engine is operating.
To further amplify the problem, the Nissan 3.3 engine is a type of engine in which pistons and valves move within an overlapping space.
Therefore, the likelihood of the valves and pistons colliding together is high whenever the timing belt slips or cuts while the engine runs.
As a result, an issue with the timing belt of your car engine usually bends the valves within the engines. In some cases, the problem can escalate by causing partial or complete destruction of one or more engine pistons.
Once this happens, your car engine can become either partially damaged or destroyed completely. Then you will need to spend more money to get it fixed.

03. Water Pump Problem
In general, the water pump of this engine is reliable. As a result, this issue rarely occurs in isolation. In most cases, the water pump fails when the timing belt shatters.
Since the water pump is quite fragile, any slight problem with it can damage your car engine.
However, a faulty water pump doesn’t fail directly. It will usually show you a couple of signs. You will probably see the low coolant light come on, which tells you the water pump is about to fail.
Subsequently, your engine will likely begin to overheat. Additionally, you may find your coolant leaking as the water pump starts to fail.

04. Fuel Sending Problem
The fuel sending problem is the only issue caused by an engine design flaw. However, amongst all the four issues, it is the least problematic for your car engine.
What is the fuel sending problem of the Nissan 3.3 engine?
The fuel sending problem is an issue associated with the fuel sending unit of the engine. This device works with the fuel pump to measure the exact level of fuel contained in the fuel tank.
When this device malfunctions in your car, you are likely going to get inaccurate readings about the fuel level in your tank.
As a result, the fuel meter on your dashboard will always show you the wrong fuel level. In some cases, the fuel gauge bounces continuously.
More often than not, you will run out of fuel on the road simply because you assumed you had enough fuel in your tank.

The Solutions of Nissan 3.3 Engine Problems
The good news is, if your car has any of these four problems, you can get it fixed.
What are the solutions to the most common Nissan 3.3 engine problems? Highlighted below are the solutions to each issue.
- Oil leaks are not as dangerous as you may think. However, leaving the problem to persist can lead to bigger problems in the future. Therefore, you should get it fixed as soon as you or your mechanic notice it. Running your car with low oil levels can damage your engine.
Your local mechanic will replace the old gaskets and seals with new ones. Doing this stops oil leakage. The gaskets and seals are generally inexpensive.
But the labor may cost you a few hundred dollars. So, if you are up for it, you can DIY and save a few extra dollars. This video gives you a look at how the gasket is replaced.
- The timing belt issue is the most tricky issue amongst the four common problems. The easiest way to avoid this problem is to periodically change the timing belt before it’s torn to pieces. The recommended duration for replacing a timing belt is 160,000 km (100,000 miles). Nonetheless, your timing belt can fail before this distance.
A ticking noise from your engine can be a sign of a failing belt. You may also see visible damage to the timing belt.
In extreme cases, you may experience unexpected power loss or poor performance from your car.
In many cases, changing the timing belt will not cost you’re a whole lot. You should want to have your mechanic do this task as chances are you may damage the water pump in the process.
- As mentioned earlier, water pumps are mostly reliable. Your water pump will fail mostly together with your timing belt. So, you need to get ahead of it and be proactive. Whenever your timing belt is due for replacement, your mechanic should look at the water pump. Besides, repairing the water pump and its working parts doesn’t cost so much, and it happens rather quickly. Also, if you need to replace it, you will not spend much money doing so. Therefore, always insist your mechanic checks the water pump when they are working on your timing belt.
- The fueling sending unit problem is generally quickly fixed. Back in the day when an extended warranty that covers the issue was still active, you could have it replaced free at your local Nissan-approved car shop. Now, you can get a replacement together with labor for under $100.
