Range Rover Sport 3.0 TDV6 Reconditioned Engine and Fitting

A client recently came to us with a Range Rover Sport 3.0 TDV6. The 3.0 TDV6 engine known as the 306dt is the successor to the now discontinued 2.7 TDV6 motor. The client advised that the engine had actually seized so we suspected a bottom end failure centered around the troublesome crankshaft in these engines.

Once the body was removed our technician immediately found a great deal of oil on the chassis bed which led us to believe that there was a hole in the engine.

By the time the engine was taken out and stripped, it was clear that there was no hole in the engine at all.  A close inspection found that the front crankshaft seal had become dislodged and allowed all of the oil to quickly flow out of the engine and resulting in it seizing.

Due to the nature of the failure the damage to the engine was extensive and it failed beyond repair.

We arranged to recondition a replacement engine for our client. Due to the common bottom-end issues associated with the Range Rover Sport TDV6 3.0 engines we always recommend line boring the cylinder block and installing a brand new oil pump.

All cylinder heads are pressure tested, skimmed and valve seats are cut.

Once the engine was assembled it was time to install the engine into the vehicle and get this baby back on the road.

Land Rover Discovery TD5 Engine Replacement and Fitting

Mr Aubrey recently came to us with a Land Rover Discovery TD5 with some engine trouble. As this is one of the older Discovery’s we were expecting to receive a vehicle in pretty tired condition to be honest. Clearly not this one though!

Bodywork and interior were both in excellent condition. Clearly very well maintained and we weren’t surprised to find a Land Rover enthusiasts invitation inside 🙂

Once we got down to stripping the engine we found that it had suffered damage to each of the cylinders. Because of the age of the vehicle this is more likely as a result of general wear as opposed to any specific parts failure.

We replaced the cylinder block, reconditioned the engine, installed a new turbo, water pump, and glow plugs. It now starts and runs like a dream!

The TD5’s are one of the remaining vehicles out there that still have that raw power.

Land Rover Discovery 2004 TD5 Engine Replacement and Fitting

We recently completed an Engine replacement and fitting service for a client who came to us with a Discovery TD5. Once we had the vehicle recovered it was clear that he hadnt just been using the vehicle for road driving 🙂

The vehicle was certainly well equipped for a lot of off-road driving so we were looking forward to meeting him in person to hear about what sort of driving he’d been doing. Unfortunately off-road driving means you are likely to get a great deal of dirt and muddy deposits throughout the vehicle, and this one was certainly no exception.

When we took the customers engine out together with the bolt on ancillaries, we found a huge amount of gunk and dirt inside his pipes and components. We spent a great deal of time clearing all of it with a pressure wash to ensure there were no blockages.

Our client had requested that we replace his air filter housing, but once we removed it we found that physically it was in good condition but just heavily blocked so we gave that a good clean out too.

Our technicians did suspect that there was a good chance that some of these blockages contributed to the engine failure. If you are planning on doing a lot of off-road driving, always ensure that your engine bay is consistently checked and give your ancillaries a good thorough clean-out from time to time.

Once we removed the clients engine we prepared a rebuilt engine for installation.

We also replaced the clients glow plugs, timing kit and water pump (highly recommended on all engine replacements).

Once the engine installation was complete we tested it thoroughly by running it up to temperature, taking it on several test runs and running a diagnostic test.

Its really amazing how much power these TD5’s generate. Those older 15p 2.5 TD engines had a great deal of raw power and we can certainly see the appeal.

Drink-driving limit could be lowered in the UK

drink drive

The UK Government has suggested that it may reduce the drink-driving limit in England and Wales, making it illegal to drive after only 1 glass of wine or 1 pint of beer.

Andrew Jones, the transport Minister has mentioned that England and Wales could follow the example of Scotland which lowered its drink-driving limit to 50mpg per 100ml in 2014. The previous limit was 80mpg per 100ml.

Scottish Police have advised that the numbers of drink-driving offences fell by 12.5% in the first 9 months since the law was changed. Andrew Jones advised that he would be meeting with representatives of his Scottish counter-parts to discuss it.

The current limit of 80mpg is one of the highest in Europe and in 2014 drink-driving led to 1080 serious injuries and 240 fatalities in England and Wales.

Although the new limits suggest that it would only take around 1 pint for you to be over the limit, in reality this would be impossible to determine because each persons metabolises alcohol at a differing rate.

With the limit lowered, motorists will also have to worry about their limits the morning after. Research by the AA has shown that almost 20% of motorists have driven the morning after believing that they may be over the limit.

Audi A4 2007 2.0 TDI Engine Replacement and Fitting

A client came to us with an Audi A4 which has the notorious 2.0 TDI 140bhp engine inside. This engine is notorious because it has a common problem with the balance shaft that causes the oil pump to fail between 60,000 – 100,000 miles which in turn causes the engine to fail.

Once the customers vehicle was on the ramp, we remove the front end. We always remove the front end on Audi A4’s to get the engine out.

Once we stripped the clients engine to examine it internally we found it was a fairly standard engine failure without any irreversible damage. Standard rebuilds are far more cost effective for our clients as ultimately they require less components and are not as labour intensive.

While the engine was out we checked over the clients ancillaries and accessories to make sure there are no other areas that require attention. We noticed that his clutch was completely worn so we arranged for a replacement for him.

We also found that his turbocharger actuator arm was sticking and not moving freely. Faulty turbochargers can significantly affect the performance of your engine as well potentially causing your engine to fail. Read our Turbocharger Faults post to help you identify the early warning signs of turbocharger failure.

After the reconditioned engine is built up, its time for installation

3 Major Signs of Engine Trouble

engine failure

As engine replacement and rebuilding specialists we often get customers calling in who are unsure if they need a replacement engine on their vehicle or not. Most people go through life without ever having to worry about replacing an engine, but those unlucky ones that do, have little to no knowledge of what to look out for. So we’ve put together a list of 3 of the major signs of engine failure to give motorists a better understanding of whats going on under their bonnet.

1) Smoking: Smoke coming from your exhaust is probably one of the most well known signs that your engine is having problems. They come in 3 distinct colours and each of them gives us a good indication of whats going on in your engine.

– White Smoke: If you’re getting a lot of white smoke coming from your exhaust then theres a good chance that you’ve either blown a headgasket or have some damage to your cylinder head. The white smoke you are seeing is actually a result of the coolant and water entering the combustion chamber.

– Black Smoke: Black smoke is normally a sign that too much fuel is getting into the engine. Most common causes of black smoke are faulty injectors, a faulty injector pump, a faulty egr valve or a faulty air filter or even turbocharger failure. If the problem isnt addressed, it can eventually lead to engine failure. The good thing about black smoke is that its an early warning sign which if you address quickly, can save you on a costly engine replacement bill.

– Blue Smoke: Theres only one thing that can burn blue, and thats engine oil. Several things can cause this to happen but the basic reason is the same – engine oil is getting into areas where it can be burnt. Now this can be happening at the top of the engine in your cylinder head where oil is leaking past valve guide seals. If so, your cylinder head will need to be removed and rebuilt. Or, this can be happening inside your cylinder block due to worn piston rings. Piston rings go round the piston, and as the piston goes up and down in the cylinder, they form a sealing surface that allows just enough oil to keep the cylinder walls lubricated. If these rings are worn, too much oil gets past the sealing surfaces and mixes with the fuel then burning off producing the blue smoke. If the problem is with the piston rings, your engine will need a more extensive rebuild.

2) Loud Noises: If your engine started producing a loud knocking noise like someone is banging at something with a hammer, then there is a good chance that you have a problem with one of the bearings either on the crankshaft or connection rod which connects to the piston. Although ultimately this means you will need an engine rebuild, the worst thing you can do here is to continue to drive it. Identifying and addressing the issue early will mean you can have your engine rebuilt at a reasonable price because no irreparable damage has been done to your cylinder block, head or crankshaft. But if its continued to be drive in this state, you could end up with a great big hole in your engine leading to a massive repair bill.

Not all knocking noises are a sign of bottom end failure in your engine. It could be a sign of something in the top end like a worn camshaft, leaking or sticking hydraulic cam lifters. If thats the case, these can be resolved without stripping down your entire engine.

3) Running Rough and Loss in Power: Loss in power over long periods of time and covering thousands and thousands of miles is to be expected. But if your engine experiences a sudden loss in power then theres a good chance that a component has failed in your engine and needs to be addressed.

In conclusion, non of us want to ever experience engine troubles, but if you do experience any of the above symptoms then we always recommend that you address it quickly, as in most cases you will save yourself on you hefty repair bill.

Turbocharger Faults and How to Spot Them

First of all there are several main causes of Turbocharger failure:

Oil lubrication:

In order for your turbocharger to work effectively it needs a regular flow of good clean oil to keep your turbocharger in the best condition possible. Always be sure to change your oil and oil filter frequently to keep your turbocharger in good health. By doing so you help to prevent the build up of carbon deposits and other sorts of contaminants that can cause damage. Fully synthetic oil actually produces the least amount of carbon.

Foreign objects:

Sometimes you can get foreign objects like broken components from the engine, small stones, dust particles etc which can enter the turbocharger from either the compressor inlet or the turbine inlet.

These can cause damage to the compressor wheels and also the turbine blades which will start to reduce the efficiency of the turbocharger and eventually cause it to fail. To prevent this from happening always be sure to service your air filter regularly and that you check your turbocharger for any deposits or particles that may be in there.

Other causes:

In addition to the causes mentioned above, over-speeding can also cause turbocharger failure, wear and tear, excessive exhaust gas temps, issues with the actuator etc.

So what are the warning signs of Turbocharger failure?

Engine warning lights:

Most vehicles these days have computer diagnostics which will pick up the turbo fault and will activate the engine management light. The engine management light can come on for any number of reasons so will you need to investigate further to find out what is going on.

Power loss:

If you notice that your vehicle isnt reaching the speeds it normally does or isnt accelerating the way it should then this could be a sign of your turbocharger wearing out.

Exhaust smoking:

If there is a crack in the turbo housing or the internal seals have broken, then you will start to get oil leaking into the exhaust system. As this oil starts to burn, it will produce grey / blue smoke which will be more obvious as the engine revs increase.

Loud whining noise: 

It can be quite common for a turbocharger that is failing to begin making a loud whining noise. If you start to hear this sort of noise coming from your engine bay then its a good shout to get it checked out.

Checking your turbo:


So you’ve noticed that some of the above symptoms are happening to you, so what do I do? Well, if your technically minded and dont mind getting your hands dirty then you can check for a range of faults by yourself by inspecting the turbocharger.

Before you get started, be sure to check the air filter, exhaust system, breather system and fuel system to make sure they are all working properly without any problems as these can cause similar symptoms to that of turbocharger failure.

So essentially what you’re looking for are signs of oil inside the turbo, excessive movement or contact between the compressor wheel and the housing. The compressor wheel should be clean, without any chips, or dents. You need to check to see that the wheel is able to rotate freely without too much movement and without making contact to the housing.

From the turbine side, it should be clean without carbon build up or oil along the surface and the blades should not have any cracks or damage. Again there should not be excessive movement or contact with the housing.

Here are a number of examples of turbochargers which failed on our customers vehicles. We always make a practice to send our clients either videos or photos of components which have failed so that they can have a better understanding themselves of what exactly is going on.

This first video shows a turbocharger which was faulty due to excessive movement in the wheel. As you can see it was far too loose:

In this second example, although the turbocharger wasnt showing too much sign movement, you can see that it wasnt moving freely and this was due to the wheel making contact with the housing.

In this final example it is the turbocharger actuator arm that is extremely stiff and making a loud noise when attempted to move by hand.

With every one of the above examples, we sent the video to our clients so that they can visibly understand the problem.

Common Engine Failure on 2.0 TDi Audi, VW, Skoda, Seat

audi vw skoda seat bre blb brb engine oil pump

A client recently called us about his Audi A4 2.0 TDI and reported that it had suffered engine failure. Before he even mentioned how it failed my response was “let me guess…..oil pump failure”. To which he responded “what?! how did you know?”.

Please dont misunderstand the above and believe that I am some sort of engine expert extraordinaire who can sense every engine that fails around the world (I wish 🙂 ). Unfortunately the case here is that oil pump failures are probably the number one cause of engine failures on the Audi, VW, Skoda and Seat 2.0 TDi models.

So lets understand a bit more about the issue. Although its the oil pump that fails, the problem actually appears to be with the balancer shaft which causes the issue.  What happens is that the drive from the slave balancer shaft that connects to the oil pump is a 6 AF hex bar and this has  inadequate engagement depth with the grooves in the slave shaft. As a result its the torsional oscillations from the balance shafts which destroy the oil pump coupling.

Technical jargon aside, if you have an Audi, VW, Skoda, Seat which is a 2.0 TDi up to around 2007 then its susceptible to this problem as after that they were built without the balance shaft.

The oil pump typically fail between 60,000 – 100,000 miles and once it happens its pretty much curtains on the engine unfortunately. So if you’re reading this and you happen to be one of the unlucky people who owns one of these vehicles, and havnt yet suffered from this failure then heres what you can do:

– First point of call is to always contact a main Audi, VW, Skoda or Seat dealer (depending on what vehicle you own). From the feedback we’ve seen it appears main dealers will not likely take any responsibility but there is no harm in trying to see if they can address this issue for your free of charge because its clearly a common defect.

– Pay a specialist engine rebuilding workshop around £1500 to get the balancing system changed to the new upgraded one.

– Sell your vehicle and purchase something a little more reliable
