Ref: Oil Pump replacement 2.7 TDV6 Engines

We have recently been made aware of some information concerning 2.7 TDV6 engine failures. The oil pump casing/housing is not sufficiently strong to withstand the stresses of tensioning the cam belt.

The cambelt tensioner is bolted to the oil pump casing. When the oil pump casing fails, it breaks at the timing belt tensioner mount, this causes the timing belt to be dislodged such that the valve timing is disrupted. As a result, the pistons and valve collide, destroying the engines valve train and causing excessive engine damage.

Modified oil pump

The pictures above show how the oil pump has been strengthened around the mounting on the new version of the pump.

We have yet to find any Technical Bulletins from Jaguar Land Rover which confirm why the mounting was strengthened or any information about the problem.

There are now many horror stories on the internet that relate to the timing belt tensioner breaking away and causing excessive damage most of which seem to affect the 2007-2008 model years. Try typing “2.7 TDV6 oil pump failure” into Google

Damaged Oil Pump

As a company, we have fitted many of these Timing Belts and Tensioners over the years without any issues but are now concerned about this new information.

We have now seen the damage caused first hand by the failure in our workshop and feel it's our duty to inform you of this new information.

We highly recommend the oil pump is changed if your engine has the original type pump.

From the 1st April 2019 onwards our company will not replace a 2.7 TDV6 Timing Belt without fitting a new updated engine oil pump.

If you require any further information or advise concerning this repair please give us call
