From the pumps I've been told about that have failed they are mechanical failures in respect that the veins have warn out due to lack of lubrication in the oil it's self, or that the pick up pipe is blocked and starved it.
How accurate that info is I'm not exact on but still food for thought even if not the exact cause. It's a shame we can't get hold of a failed pump or a few and a new one to make comparisons from directly. |

I own a garage and specialise in vw & Audi repair , tuning . Over the past few years we've seen lots of 2.0 tdi engines with oil pump problems .
The early engines had a oil pump driven via a chain . On these the chain tensioner would fail causing the chain to slip on the oil pump sprocket . The later engine used a gear driven oil pump . These also have had plenty of failures due the the pump shaft becoming worn resulting in no oil pressure . Most of the time a repair is possible . We have replaced lots of oil pump pick up pipes on the older 1.8T engines as they block with sludge ... Does anyone know what the exact problem is with the ford engine ??

yep its a variable displacement pump and as far as I know its a concentric pump not a vane pump
and the few ive seen and heard about were drive failures |

Not on a Defender or Transit, however this is a pic I came accross on the Mazda forums when researching their engine issues.
The strainer on the engine in question was the same....full of carbon.  Click image to enlarge |

Wow that is bad. This for sure was a starvation problem

So the failure could be down to lack of oil flow due to a blocked oil pick up .. I would recommend the use of a good oil flush at every service ..
Change the oil every 5k and replace the oil pick up every 20k |

Apparently the standing advice for these Mazdas is regular oil changes and sump removal every 12-18 months to clean the strainer..... how easy it is to remove the sump I have no clue.

Looking on Topix the pump is chain driven. No updated chain or tensioner. No updated pickup pipe. Yet FOUR part number changes for the pump it's self

It would be interesting to see in one of the Ford 2.2s when the sump is removed after oil pump failure, to see if we are getting the same clogging issues.
The first that my friend with the Mazda knew was the oil light flickering, then 400 metres further down the road seizure. Jonno |

Obviously a weakness or two identified in the pump then. By the sounds of it they don't know how to fix it..... I think if I had a engine that failed out of warranty I'd be suggesting legal action to get a LR contribution, as there is obviously some issue. LR can then take it up with Ford... This and the filthy oil issues that can happen doesn't bode well. Jonno |

Though I've not removed a sump from a 2.2 I do have an engine out from my 3.2 build and even on the car it looked easy to do.
My Ford Ranger is at 5k miles now so I'll drop the oil soon and have a look with the camera in the sump for any debris. LR029912 is up to ca444444 LR036454 is from ca444445 to da444246 That part number changed to LR055351 in Same vin range Then LR058095 is for da444247 on wards, all these part numbers now supersede to LR058095 Last edited by bell-auto-services on 1st Mar 2015 3:39pm.

On the Audi engines I've always put it down to "long life serving " that's a terrible idea to let a engine go for 2 years or 20k without a oil change ..

I agree with you. Long life servicing can not be good at all.

yup long life servicing, fuel contamination of the oil and even the EGR recycling *rap back into the engine doesn't bode well for a long life engine ! Jonno |
