I hope there are not to many more threads like this popping up in the future.

Any idea if it was someone on here?

Something that surprised me is that they have complete engines in stock in Australia - available for next day delivery.


Why would I need to be worried if they monitor this thread? I haven't made any accusations, just speculation. It broke. I don't know why. It's going to be VERY expensive.

Was just letting you know,I would approach them and ask for assistance in replacing the motor at your least possible cost.A 2009 vehicle with a failed engine,they should last much longer.

Heads are now off, tiny scratches not even getting through the layer of carbon are the only damage. So the heads are good.


Then the bad news - the disintegrated bearing and has clearly made it's way through all of the oil lines, turbos and all, meaning that it would all need to be stripped and rebuilt.


The only thing I am really waiting on now is the breakdown of the oil/coolant heat exchanger to verify if there is any blockage in it that could have restricted the flow of oil.


Then I guess i'll ring Land Rover, share what I know, and see what they have to say.


Does anyone have any experience of raising concerns with them? Any tips?

Where on the rod? I haven't looked inside one of those engines, but where else are rod bolts other than on the bearing caps (except maybe locating gudgeon pin bushes, but that's pretty old school )

Seems like I may have used the wrong term to describe the wrong thing, and ended up saying the right thing. Or at least conveying the right thing. Who said two wrongs don't make a right? :-)


The bolt that I am referring to is one of the pair that hold the big end around the crankshaft. You are right, they are the only bolts on the rod.


What I was originally trying to describe was the bolts that hold the crankshaft in place. Those are all fine.


Hope that clarifies.

Assuming that the engine has not been rebuilt at any prior time, I would be asking LR about the historical records of early engine failure as mentioned in earlier posts. Conrod bolts don't just fall out. Even if the rod breaks the bearing end is usually intact.

I made no assumption on which bearing caps were involved, con-rod or main bearings. just that any coming loose would have catastrophic results.

If a conrod bolt came loose wouldn't there be a hell of a lot of noise well before the bolt fell out?
