Another XF 3.0 diesel blown engine (at 53,800 miles)
Discussion
I'm seeing similar stories from other owners. I've a 60 plate XF 3.0s which went clatter clatter BANG and seized with utterly no warning. It seems the oil was contaminated with diesel and although the oil was indicating 'full' on the dash gauge it seems it was mostly diesel. A horrible experience!! Jaguar not interested, despite the Glasgow dealer (Taggarts, who were most helpful) attempting to negotiate on my behalf. It is now with a small engine rebuild company, The Engine Workshop in Dumfermlne, who are about to take on the job. The workshop is strewn with JLR 2.7 and 3.0 engines, the engineer explaining that he would have focused exclusively on these if he'd known how succeptible to failure they were. He gives a 24 month unlimited mileage warranty, so I'll keep you posted on the success ofl the repair.

Do you know, or did the engineer say, what specifically caused the fuel and oil to mix, as in where/what seal/gasket etc? I was looking at a 3.0d XF - therefore quite interested!OldGermanHeaps said:
Is the diesel contamination coming from dpf regens?
You mean like in Mazda 6 engines from 2007-2012 ? These too were very problematic, and required more often oil change, after the factory was aware of the problem. Wonder if Jaaag said anything about it in their service comunications?I don’t yet know where the diesel came from, but incomplete regen. seems to be the common cause. I’ll know more once the engine has been stripped. Also the oil pumps seem prone to failure too. Engineer recommended change at 4 yrs/48k.
Cost of rebuild £2.9k+vat. Inc crankshaft grind and balance, cylinders polished or lined if needed, main and big end bearings, rings (or pistons if needed) timing chain, oil pump, seals gaskets etc. Possibly valves too, can’t remember!
I will keep you posted, and I’ll pass relevant comments to Engine Workshop. Thanks.

How big was the bang? Hopefully it wasn't a rod snapping as the block will be scrap.
I was thinking of buying one of these as a main car before we got the allroad, now i might keep my eyes peeled for a cheap knackered one to diy rebuild as a third car, i hadn't heard these were prone to problems, but if they are there must be a few projects available cheap somewhere.

Bang not too big fortunately. The breakdown happened as I was parking up, with engine idling so far better than 70 on the M74 minutes earlier!! I've seen xf's advertised 'needs an engine' so they are available. If you do it yourself you'll get a bargain, don't over fill the oil, and JUMP if the level creeps up at all! ...Oh for that non existing dip stick to check what's in the sump!
I'll find out. Could be 3rd party parts I suppose. Anyway, I've very little option as dealer would charge about the value of the car to replace engine. Due to the JLR policy of giving the driver no warning lights or instrumentation you don't know when a dpf regen cycle is in progress, or if you're stopping during an incomplete cycle, in which case the over fuelling involved will inevitably contaminate the oil. Apparently these engines will survive, but only within certain parameters/driving styles which would make them a difficult sell in the first place. Leave oil at 3/4 and check daily for ANY rise is level. You can guarantee its not oil......
One owner does a 60 mile round trip to nowhere in particular twice a week to ensure complete regen cycles. Might have to plan similar in to my schedule.
