You can get a new stripped engine. Basically a Ford engine with a Defender oil sump. Puma 110" SW

2.4s are harder to get new. Its a shame for a vehicle that is 16 years old.
Not considered getting a full assembled head, and perhaps service the bottom end? 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

Yes we have ! Spent all day on the phone ! New stripped down are approx £5K and you don’t even get a timing chain  |

Not really! Thought getting a new engine would be a better investment. Anybody know why they get so full of carbon / crap ? The sump was like an ash pan on a wood burner  |

How often did you change the oil and what oil? Puma 110" SW

It’s a combination of the EGR gases and breather oil mist being combined and fed into the inlet manifold. Allegedly good for emissions but not good for the engine. That’s why some blank and map out the EGR and fit a Provent catch can. |

The EGR and breather would gunk up the inlet manifold, but should not create the problem / issue with the oil in the sump as described in the OP. I would say low grade engine oil that degraded / carbonized too quickly. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Good quality 05w/30 every 6k or before 12 months for the last 5 years ( 40k Km’s) but obviously don’t know for the 260 k Km’s with previous owners ? |

Particularly surprising when you consider the number of different vehicles which have used the Ford 2.4 Duratorq engine. It's bizarre, and probably symptomatic of the throw-away society in which we now live. |

This is not quite correct, there is always a bypass past the piston rings; Ianh nails the problem. |

Thinking about it, maybe you have a point there. I always thought most oil contamination occurs during the power stroke. But a diesel should be constant pressure, although unsure if that still holds with modern diesel cycles with pre, main and post injections.
My old 19J had huge cracks in all 4 pistons, with huge back pressure that used to lift the filler cap off the rocker cover, and ran like that probably most of its life, oil was regularly changed though, and was always so black, but when engine was stripped, there was minimal sludge, and no carbonization. No egr on that lump. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

I can't see that the exhaust gas recirculation would have any effect on what is going on in the sump..if the blow past the piston rings is causing a carbon build up in the sump then what or how is that effected by the exhaust gas recirculation ..
some engines , and notably some transits suffered from carbon build up in the inlet manifold which was attributed to the egr...I can remember doing a mark7 2.4 engine and cleaning the inlet ports. the egr valve was blanked and the function had to be deleted from the ecu, because on that engine I think it was the manifold absolute pressure sensor gave feedback on the operation of the egr valve, so you couldn't just blank it  Click image to enlarge |

Well ! All I can say is that I’ve dropped a few sumps in my life notably every single TD5 I have bought ( about 6 ) to check that the bolt on the oil pump is tight and have never seen as much crap as I have just seen in the bottom of this 2.4 tdci which was obviously the cause of this engine failure!
