5 Land Rover V6 Diesel Engine Problems (Explained)

All vehicle engines are sometimes susceptible to damage or issues caused by general wear and tear, and the Land Rover v6 diesel engine is no exception.

And, just like any other engine, knowing the most common problems and how to spot them can save a great deal of time, energy, and money.

The most common problems a Land Rover v6 diesel engine might face are oil starvation and crankshaft damage. Other potential issues like overheating, worn or broken timing chains or tensioners, and clogged filters can also occur.

This article explores the most common engine issues for Land Rover v6 diesel engines and what can be done to prevent them.

What is the Most Common Problem for a Land Rover v6 Diesel Engine?

The most commonly reported issue is Oil Starvation, which can result in parts that are not properly lubricated and suffer abnormally high wear and tear.

It can even result in outright breakage if not caught soon enough.

The reasons behind oil starvation are usually traced back to one of two concerns:

  • Improper levels of oil
  • Oil Pump Failure
  • Low-Quality Oil

The last consideration is owed to the higher performance potential of the v6 diesel and the concern that lower quality oil, or oil without the correct mix, can clog up the engine and cause damage to the cylinders and camshaft.

How Can I Prevent Oil Starvation Damage?

  • Regular use of the car will help keep oil circulating and prevent issues caused by long-term disuse.
  • Make regular checks to ensure that oil levels are where they should be.
  • You should also take your Land Rover in for regular maintenance and oil changes.
  • Suggested schedules for maintenance include a check every 6 months, or 5,000 miles. Recommended oil and oil filter changes should occur every 7,500 to 10,000 miles.
  • Make sure you use the recommended type of oil for your engine and oil that is specifically formulated for diesel.
  • Seals should be checked for wear, drying, or cracking, and replaced as necessary.
  • Regularly have a mechanic make sure the oil pump is in good condition and working properly

How Do I Know If I’m Having a Problem With Oil Starvation?

Common indicators are rough-sounding engine or grinding noises.

Other indicators include lower fuel efficiency or more noticeable wear and tear on parts of the vehicle.

You may also see oil smoke coming from the exhaust if there is a problem with oil distribution.

What Can I Do If I Have This Problem?

Check the oil levels to see if they are low.

You can add oil to at least perform a temporary form of maintenance, but the best thing you can do is take the car to your mechanic.

A mechanic will be able to determine the exact cause of the oil starvation and any underlying issues, such as leaks, and perform appropriate repairs.

What is The Second Most Common Problem Reported for a Land Rover v6 Diesel Engine?

The second most common issue for Land Rover v6 Diesel Engines is camshaft breakage, which often causes serious damage to the engine.

Camshaft breakage can happen in any number of ways.

  • The timing and tensioner chains can go bad or become over-worn.
  • Another part can come loose and wind up, impacting the camshaft.
  • Bearings can fail

In any case, if your camshaft breaks, you’ll need to get it repaired. If not handled in time, it can result in expensive repairs or even require the replacement of the entire engine.

How Do I Know If I Have a Problem With the Camshaft?

There are several indicators of a potential camshaft problem. In many cases, the check engine light will come on, but if it doesn’t, signs to look for include:

  • Loud clicking or tapping sounds
  • Metal in the engine oil
  • Frequent backfiring or popping sounds
  • Cylinders misfiring
  • Increased emissions and decreasing fuel efficiency

Experiencing one or more of these indicators means you should probably get your car to a mechanic as soon as possible.

What Can I Do If I Have a Camshaft Problem?

The best thing to do if you have, or think you have, a camshaft issue is to take it to a licensed repair shop and have a professional mechanic take a look.

The sooner you get it in, the fewer repairs and expenses you are likely to have, so act promptly if you notice any indicators of potential damage.

What Are Other Problems a Land Rover v6 Diesel Engine is Likely to Have?

Other potential problems that are somewhat common in Land Rover v6 diesel engines include:

  • Overheating
  • Worn or broken timing chains or tensioners
  • Clogged Filters

Any one of these can cause significant problems with your engine.


Overheating is usually a symptom of either low coolant or another, deeper issue. Many cars have an indicator on the dashboard to warn you if this happens or is about to happen.

If the indicator does not come on for whatever reason, you’ll probably see smoke coming from under your hood.

If overheating occurs, it’s best to do the following:

  • Stop the car immediately or as soon as possible and allow the engine to cool.
  • Check the coolant levels and add coolant if needed
  • Take the car to a mechanic to make sure the radiator is working and that all seals and assorted parts are in good working order

Timing Chains or Tensioner Wear:

Both of these issues can cause slippage and damage to the engine and should be dealt with promptly.

Signs include:

  • Rattling engine
  • Failure to start
  • Misfiring engine
  • Contaminated Oil

If you suspect the timing chains or Tensioners are worn to the point of failing, it’s time to take the car in for maintenance.

Regular maintenance checks should be performed to make sure the chains are in good condition, even if you’ve encountered no indicators of problems.

Clogged Filters:

Clogged filters, whether they are fuel or oil, can result in poor engine performance. Signs include:

  • Poor fuel efficiency
  • Misfiring
  • Stalling
  • Difficulty starting

These can be avoided by regular maintenance and replacement.

Keeping up-to-date with your regularly scheduled maintenance should include cleaning or replacing all filters.
