Common Land Rover 2.7 TDV6 Engine Failures

3.0 tdv6 rebuild

Land Rover 2.7 TDV6 engine broken crankshaft: Upon inspection the crankshaft of this engine by design incorporates weak spots in the area between the rod bearing journals and counterweights. Over a long period of a high stress or an aggressive driving style these points on the crankshaft fail. This seems to still be the case on a vehicle with the correct maintenance history. A related issue with the lion v6 is engine failure causing spun main & big end bearings. Oil starvation can be another less common cause for engine malfunction, as well as turbocharger overrun. Issues resulting from listed failures include: snapped camshaft chains, damage to fuel injectors, heat damaged and melted pistons.

We commonly carry out engine rebuilds on the 2.7 TDV6 most commonly fitted to the Land Rover Discovery and also the Range Rover Sport, as part of this we replace the crankshaft. This is a very important step in ensuring a reliable high quality engine that will last.

Another common fault with this engine is the tensioner mounting/oil pump failure see below.

Tensioner Mounting

Oil Pump

A common problem with the 2.7 TDV6 is the oil pump housing has a weak point where the tensioner is mounted. This point eventually breaks under the high stress in this area and causes failure. Every 2.7 engine rebuild we carry out has the oil pump replaced with the newer upgraded oil pump. The upgraded pump has reinforcement in the vital stress point so this issue is resolved.

Engine History

For a long time the only Land Rover diesel engine was the four cylinder unit, after this came the BMW era with Land Rover’s Td5 and the BMW six cylinders. BMW then sold Land Rover to Ford and it wasn’t an option for Ford to buy BMW engines anymore, plus BMW development support had ended. The existing engines needed to be updated so a new diesel engine had to be produced for new Land Rovers. 

Ford had been working with PSA Peugeot Citroën on a series of smaller diesels for Peugeot and Ford cars, so it made sense to produce a bigger unit to suit Land Rover’s and Peugeot’s larger car needs. However Peugeot wanted a 2.5 litre engine and Land Rover wanted a 3.0 litre unit.

A compromise was made at 2.7 litres and work started at the PSA engineering centre in Paris. Engineers from Land Rover were involved to ensure the engine would work for the particular demands of a Land Rover application. This engine was then fitted to the Discovery 3, and the later Range Rover Sport. Compared to many similar, and older, engines the TDV6 is of relatively light weight. It’s made from a compacted graphite iron block which has thinner walls without losing any strength. Dry it weighs in at 205 KG. In 2009 this was updated to the 3.0 TDV6.
