If the valves have hit the pistons you may find the rockers have snapped.
You would need to remove the inlet manifolds to check

If as you say in an earlier post the timing cover has split open, then it's highly likely the oil pump has failed. You will not be able to fit a belt and re time it for damage assessment without replacing the oil pump first. The timing belt tensioner is bolted onto the oil pump, and it is the casting here which holds the tensioner that has failed.
All you can really do for now is to remove the cover to confirm oil pump failure, or otherwise. yµ (idµ - eAµ) ψ=mψ

Well, I wasn’t expecting that!
So, a couple of hours of carefully taking the engine bay apart and I now have confirmed what the issue is. Or at least part of it!
The drivers side cam pulley has sheered off! The belt is still attached and the tensioner is keeping it nice and tight, it’s still on all other idlers and pulleys. That I guess would explain why it sounded like it was running on one one bank! It also explained the horrendous noise thta I had on the last attempt to start as the the belt and toothed part of the pulley would simply have been spinning but not attached to the middle of the pulled bolted onto the cam!
Light is fading for today so I have packed up for the day now as I’m outside on the road where the aa dumped me. I guess the next step is to have the top off that bank and see what it’s looking like inside. No really sure what I’m
Looking at but every days a school day right!
Any advice of next steps would be greatly appreciated, otherwise I’m sure I will work it out. Will try abs upload a pic of the damage too.
Is there a chance that the pulley could be replaced and everything ok? I’m
Guessing not as it’s been turned over a good few times as it was a suspected fuel issue to start with!2008 Disco3 2.7 Tdv6 HSE

I suppose you'd have to think there could be valve or camshaft damage given your attempts to get it started. The cam cover removal is the only way to know for sure and both sides will need checking in case the belt / timing has jumped.yµ (idµ - eAµ) ψ=mψ

There is absolutely no way a pulley shears like that on its own without another major problem in the engine somwhere.
Crank snap is one thing that can lead to this or a timing chain between the 2 camshafts has snapped or something like that.
Remember most engine investigation will require body of and probably a replacement engine because its not economical to start replacing parts due to time consumed and parts required.
An engine supply and fit is the best way to go here in my opinion.
There will most probably be damage to at least one cylinder head, pistons, conrods and even crank shaft would have taken a beating and with its history of snapping crankshafts it would be all over for that engine.
Even a full rebuild wouldent garantee that it would last.

Could be your timing chain on that bank has snapped allowing the pistons and valves to come into contact, then the sprocket gave in due to the stresses placed on it trying to start.
There's only one way to find out and that's cam covers out, if you're lucky there's not more sinister hiding in the crankcase.yµ (idµ - eAµ) ψ=mψ

My totally uneducated guess is that the other side is still ok my reason for this, is that on stating the engine did run but it felt like only on one bank. That would
Make sense as the pulley is toast on the other side.
I totally agree that a pulley shouldn’t snap
Like that unless there is an issue elsewhere but I was hoping it wasn’t the crank because the other side appears to be running as expected. I’m tempted to pull the faulty side apart to see but I’m
Not sure if I have the balls to do that or perhaps I should
Just leave it to my local indie as they will know the ropes much better than me.
The initial issue started at a standstill so low revs, I was hoping this could mean the damage if any was not too bad. But perhaps that’s juts the optimist in me.
It’s def going to have to come apart I’m sure but I think I would rather someone that knew what they were doing did it now as I’m
Not convinced that even if I do pull it apart if I will know what’s right and wrong! Lol
Thanks for all the input folks, I wanted reassurance for sure and it would have been great it there was a ray of light somewhere for me to hang onto but I’d always prefer the truth and if that’s that the engine is toast then that’s the way it is. I’m
Loathed to replace unless I have to but I do think this could juts be a symptom
Of other issues and not the root cause maybe.2008 Disco3 2.7 Tdv6 HSE

You can't really blame the garage. Are the 3 bolts tight ?
You best get on and fix it !
Having seen the pic, I'm still thinking this,

If it runs there is hope.
May need to put a 2nd hand head on it, which are about £100 on eBay.
Gaskets, head bolts, and stuff add up though.

Cheers Pete. Great question on the bolts! I didn’t even think to check! Lol. I will now though!
I actually really wanna do it myself as I’m learning as I go which is a good thing in my eyes? I just don’t wanna get in too deep if it means what I do makes the rock of my indie harder!
I’m keeping things together as I go abs screwing bolts back in where I can so they don’t get mixed up.
The forum is great as there are always differing views and some are half full and some are half empty. Am some have already left the pub and gone down the offie! Lol
So the question is, when I lift the cam cover off, what do I want to find? Loose cam
With stretched bolts? Snapped chain as well maybe? I assume that movement up top in the event of things out of timing is much better than the cam being nice and solid which could mean more damage lower down?2008 Disco3 2.7 Tdv6 HSE

You will have bent valves and broken cam caps.
The answer is always to fit a second hand head.
Just need to check the pistons aren’t cracked.
Not known that to be a problem though

Ouch!
Hope that a head swap gets you back and moving again!
Whilst it’s apart it’s worth replacing the oil pump and also sorting replacement glow plugs!Must stop buying shiny toys....

Ok, question for you knowledgable lot. Actually 2 questions. How doable is stripping the heads without lifting the body? Is it worth me trying? I don’t have the ability to lift the body where I am so I’m pondering whether it’s worth me even trying.
Second question is, are all the 2.7 engines the same heads? Or are the later engines different? Mine is a 2008 so the later engine but I’m not sure if that changes the head at all? Just looking at used or recon ones on eBay abs want to make sure I’m looking at the right ones.

The good news is the drivers side head is much easier to remove
And yes you can do it body on.
I think the heads are the same. 98% sure
Try and get a head with cams included
And you will need a sprocket too of course.
