Toyota 5.7 V8 Engine Problems: The 3 Most Common Problems

Toyota 5.7 Engine Problems

Tundra, Sequoia, Land Cruiser, and Lexus LX 570 were among the vehicles to get Toyota’s 5.7-liter V8 when it was introduced in 2007. Known as the Toyota 3UR-FE, this engine will continue to be used in Toyotas through 2021. It has 381 hp and 401 lb-ft of torque, which are respectable numbers.

It wasn’t too long ago that Toyota offered an optional TRD supercharger that increased power and torque by 504hp and 550tq. Despite its many advantages, the 3UR-FE isn’t perfect. The reliability of the Toyota 5.7 V8 engine is discussed in this article.

What Cars Use the 3UR-FE?

The following vehicles are powered by Toyota 3UR-FE 5.7L engines:

  • 2007-present Toyota Tundra
  • 2007-present Toyota Sequoia
  • 2007-present Toyota Land Cruiser
  • 2007-present Lexus LX570

Note: For a few years and models, the 3UR-FE was available as an option rather than as the standard engine.

3 Common Toyota 5.7 V8 Engine Problems

Toyota 5.7 V8 Engine

The following are some of the most frequently encountered problems with the 5.7 3UR-FE engine:

  • Cam tower leaks
  • Water pump
  • High oil consumption

This article will cover all of the above topics in detail, and then we’ll wrap things up by talking about 3UR-FE reliability as a whole. Before we get started, however, there are a few things to keep in mind.

There’s a good reason why these are listed as the top Toyota 5.7 engine issues. This does not imply that the issues are widespread. Instead, these are some of the most common places where things go wrong.

It’s also been 14 years since the 5.7 V8 debuted. In the short term, newer models will likely be more dependable due to normal wear and tear that comes with increasing age and mileage. That being said, the Toyota 5.7 is a long-lasting powerhouse.

1) Toyota 5.7 V8 Cam Tower Leaks

Contrary to popular belief, Toyota 3UR-FE engine cam tower oil leaks are a common occurrence. Look up terms like “cam tower” and “camera tower” to learn more. The Toyota Tundra and its 5.7-liter engine are the subject of nearly all of the top search results. Yes, the internet has a proclivity for exaggerating the importance of small details. For example, repairing leaks in the Toyota 3UR-FE cam tower is an expensive proposition.

Toyota seals the valve covers rather than using a gasket around the cam towers, which are located under the valve covers. The sealant on the cam towers degrades over time, resulting in oil leaks. Toyota cam tower leaks usually begin at the rear, allowing oil to drip onto the hot exhaust manifold. Since it can lead to fire and safety issues, it’s critical to address this problem.

Again, the Toyota 5.7 engine’s cam tower leaks are a common issue. Look for problems between 50,000 and 100,000 miles. Leaks, on the other hand, have appeared much earlier. It’s a costly problem, so haggling Toyota to help or cover the repair costs has worked for some Toyota owners.

3UR-FE 5.7 Cam Tower Symptoms

The following are signs that the 5.7 V8’s cam tower seals are leaking:

  • Visible oil leak
  • Burning oil smells
  • Smoke from engine bay

Toyota cam tower leak symptoms are simple. Even if you see a leak, it’s possible that no oil has leaked because the leak is burning off. You’ll probably smell burning oil and see a little smoke if it drips onto the 5.7 exhaust manifold.

5.7L V8 Cam Tower Oil Leak Fix

Removing the valve cover is necessary to fix an oil leak in the cam tower (s). That alone is time consuming, but it’s only the beginning of the task. The video that follows gives a good idea of the amount of work that goes into this position.

Those with reasonable experience and knowledge should be able to do it themselves. Toyota 5.7 cam tower oil leak fixes, on the other hand, can cost upwards of $1,500.

2) Toyota 5.7 Water Pump Problems

It’s not uncommon for engines to have problems with their water pumps, so the Toyota 3UR-FE 5.7L isn’t the only one. Water pump failures on the 5.7 are less common than cam tower failures.

The weep hole in water pumps allows coolant to escape. Coolant leaks from the weep hole when the seal or bearing inside fails. Using this method, the water pump is kept from doing any more harm to itself.

Fortunately, the Toyota 5.7 water pumps fail in exactly that manner. The water pump is still doing a partial job of circulating the engine coolant and controlling temperatures. A fix should be made as soon as possible for the 3UR-FE engine’s failure. At the very least, the engine doesn’t have to be shut down immediately due to a catastrophic water pump failure.

The 5.7L V8’s water pump is much less likely to fail catastrophically, but it could still fail catastrophically. However, if this happens, make sure to turn off the engine immediately to prevent further damage from occurring due to severe overheating.

Toyota 5.7 water pump leaks usually appear between 60,000 and 100,000 miles into the car’s life. Even after 150,000 miles, a lot of these pumps are still going strong.

3UR-FE Water Pump Failure Symptoms

Water pump issues on Toyota 5.7 engines can manifest as the following symptoms:

Coolant leakage from the weep hole is the most common cause of Toyota 3UR-FE water pump failure. If you don’t fix it, you’ll have a leak and low coolant. Overheating, a check engine light, and fault codes can all result if the 5.7 V8 pump fails completely.

Toyota 5.7L Water Pump Replacement

The Toyota 5.7 water pump replacement is very affordable in comparison to other models we’ve discussed. On its own, a 3UR-FE water pump costs somewhere between $70 and $150. While you’re in there, it’s a good idea to swap out the thermostat and serpentine belt.

The 5.7 V8’s DIY water pump jobs are simple, but accessing the pump takes some time. The Toyota 5.7L water pump replacement takes about 3-6 hours of labor, so plan on paying an additional $250-600.

3) Toyota 3UR-FE High Engine Oil Consumption

Toyota 3UR-FE High Engine Oil Consumption

Alright. This is something that shouldn’t be on the list, in our opinion. Oil consumption on the 5.7-liter V8 may be an issue for some. The good news is that it doesn’t appear to have any negative effects or reliability issues. Consequently, we’re talking about high oil consumption because we’ve run out of other topics to broach.

Here’s what’s going on: The Toyota 5.7’s high oil consumption could be at least partially explained by the engine’s piston ring clearances. It’s also possible that low-quality oils were previously used. The PCV (positive crankcase ventilation) system is an additional consideration. Faulty PCV valves have been linked to higher oil use.

Again, we’re only bringing it up as a discussion starter. The 5.7L 3UR-FE is a great engine in all respects, and there aren’t many issues to bring up. As far as overall dependability or longevity are concerned, a high oil consumption does not appear to have any negative consequences.

Reducing Toyota 5.7 Oil Consumption

There are a few things you can do to help save oil on the 3UR-FE, including:

  • Quality synthetic oils
  • Heavier weight oils
  • Check/service PCV system
  • Avoid excess idling

Some research suggests that using high-quality synthetic oils can help cut down on oil consumption. The Toyota 5.7-liter engine runs best with 0w20 engine oil. A thicker oil, such as a 30 weight, may have less blow-by than a thinner oil.

Excessive idling, particularly on a cold engine, can increase oil blow-by, so watch out for that as well. Otherwise, make sure to have the PCV system checked and serviced.

A certain amount of oil consumption is inevitable, and it has little to no impact on a system’s dependability or longevity. Excessive oil consumption, on the other hand, could signal a mechanical problem. However, this is a rare occurrence, as the 5.7L V8’s oil consumption is primarily due to normal operation.

Toyota 5.7 V8 Reliability

Reliability of the 5.7-liter Toyota 3UR-FE engine If you ask us, we’d say the Toyota 5.7 engine gets top marks for dependability. Two of the most common issues owners encounter are leaks in the cam tower oil and the water pump. Although repairing leaks in the cam tower oil can be expensive, the problems are undoubtedly exaggerated.

Other than that, the 5.7L V8 doesn’t have many common problems. Owning a car or truck means you’re going to run into issues with your engine from time to time. There are numerous moving parts in engines that are prone to damage from misuse and neglect. If you want a great experience from your Toyota 5.7 V8, you must keep it well-maintained.

Always use high-quality oils, replace fluids on schedule, and address issues promptly when they arise. If you do all of these things, there’s a good chance the 3UR-FE will perform admirably. The 5.7-liter Toyota engine is built to last well past the 250,000-mile mark.
