Mine kept smoking for a few trips. The oil collects in the V of the block and slowly trickles down. Just wait a couple of weeks and it will be gone. I went round a really sharp bend and got traction control kicking in, then 10 mins later smoke pouring out!! I thought a seal had failed but it was just more oil coming out of the V. It's not easy access to use degreaser. Time will do it better. 2012 L322 4.4 TDV8

Many thanks to mm289 and others for vital info that enabled me to (almost) sort out my oil cooler / O ring leak. Brilliant.

At least it's not an oil leak!! I was suspicious of that connector when I did mine. Seamed to connect too easily and I couldn't feel any O ring or something slide over the male part. Seemed to form a seal tho! 2012 L322 4.4 TDV8

Years ago I bought a selection box of O rings off ebay and have used them numerous times on various cars for such occasions. Might be worth a try. |

Thanks Alan and Kevin. Yes it clicked on perfectly - I guess as little resistance. It was dripping out quite fast once engine running. I've a feeling it's the top of the three-way EGR cooling pipe?? Anyone changed one? |

The T-piece with its 3 hoses is LR022718. I'd be looking for a suitable o-ring. |

Found this surprise .....
So got the car towed to the JLR dealer. Only for "checking" what is wrong, they charge € 320,00. Repair would be at least € 3.000 (including parts & materials) ..... Diagnose was clear (and expected) -> Oil Cooler leaking! So got online and found an Oil Cooler for just € 85 which came including both gaskets!!!! Moved the car to a workshop of a friend (with all equipment ![]() ![]() Last Saturday we decided it was time for a change. Everything came of quick and the progress was good. We did not break anything! ![]() Installing the rings ![]() ![]() Installing the gaskets after cleaning the base ![]() ![]() So far so good ....... But then, when reinstalling the bolts ...... They broke without even giving it the correct torque So we had to uninstall and reinstall the ![]() ![]() The best solution we found is to use new bolts, which did the trick. During the whole process we ruined the thread of the bolt next to the oil return from the Turbo, which also led to one uninstall and reinstall. ![]() After all, we had a nice day working to get it fixed, but it is running perfect again. In the end the costs where € 900 including the towing, cost for the diagnose at the JLR dealer, oil cooler & gaskets, new bolts, oil filter, oil and some labor (the friend does not come free .... ). Keeping a close look the coming weeks if it stays dry, but for now, I am a happy fullfat"er" again. The posts on fullfat were extremely helpful and spot-on ![]() ![]() (EGR out, 380HP, 800Nm) |

Well done on the repair. Very strange having the bolts shear, especially when there's a rubber gasket below. 2012 L322 4.4 TDV8

Pretty sure I have now sorted the oil cooler leak - many thanks to wisdom imparted on here which made it possible.

That o-ring is cooked like the cooler gaskets and the o-rings on the turbo oil feed pipe, so I'd keep the Viton ones with spare oil feed pipe o-rings where they'll be found when next needed. Thanks for the sizing - I'll procure a couple for when mine fails. |

There's 2 types of oil leak from the cooler. 1 from the O rings as you mentioned, then also a gasket (2 gaskets) failure on the cooler itself. If you go to the top of this topic and follow the comments you will be able to find where to look to see if it's the O ring at the back. If it's O rings, it's a 20 minute job. 2012 L322 4.4 TDV8
