Hi
So I'm new on here and desperate for some help. I bought my Range Rover in May this year. I was driving down the motorway when thick black smoke started pouring out of the exhausts. The engine fault message was displayed on the dashboard. I pulled over and turned the engine off and smoke was coming from underneath the bonnet. The RAC came out to recover it for me and plugged in the diagnostic tablet. The error message said loss of pressure. He lifted the bonnet to have a look and there was a spilt hose, when he removed the engine cover to get better access it revealed several holes in the rocker covers. One of the holes looks like it basically melted through (left side) and one looks like its blown a circular hole (right side). I have attached pictures. Anyone seen this before or any idea what it might be?? Any help is greatly appreciated. Cheers

That doesn't look good.

TDV6 have issues with oil pumps, looks like it overheated due to no oil pressure, blew the coolant hose of exacerbated the inevitable toasting....... and it threw some rockers.

Any unusual noises prior?:rolleyes:
 
Crank case pressure has blown the oil filler cap out, any indication on temp gauge prior to melt down ?
 
The tdv6 engines are known for snapping crankshafts though not sure if that would blow holes in the rocker cover but I guess it's possible.
Might be worth an ask on the disco section as yours is basically a disco 3 in a frock.
If the engine is terminal, it's the same engine in the 2.7 diesel s type jag. You can buy the whole car for a grand so don't go paying 4k for an engine!

No, no unusual noises prior to melt down just came out the blue. The coolant light had come on 2 weeks prior and had been topped up.

Thanks for that. Good to know.
 
Whip those covers off.

Just realised there are no rockers, but the timing belt drives one camshaft which then turns the other via a chain at the bulkhead ends of the shafts.

that looks like egr stuck open and carbon build up caught fire and burned inlet manifold
the inlet manifold is part of the rocker cover
mine burnt out the y shaped inlet manifold but not rocker covers

If you use a Jag engine the turbo arrangements are different. 2 turbos on the jag, one on the RR sport

You will probably get away with new or second rocker cover inlet manifold and renewing the faulty EGR valve or blanking the EGR off. any OBD11 reader will tell you what valve is faulty i used a cheap one to clear faults on my Disco 3 while i was waiting for my NANACOM to arrive. if you go the blanking route you need to remove tathe butterfly valve in the inlet manifold and get a software patch to turn the MIL light out so it passes the MOT. Take no notice of the broken crankshaft or oil pump at this stage as they are at the bottom of the engine and this is at the top. On your model it hasthe later oil pump housing so that should not be a problem BBUT renew the cam belts at the required service interval. I dony know if jag manifold s are the same but over here the ford territory engine is practically the same with a few minor thing to change over. On my disco the EGR valves are doable but a very fiddley job and you need hands like a baby with the strength of tarzan.

The chain drive for the camshafts is at the front of the engine behind the timing belts not at the bulkhead end but the fuel pump belt drive is at the rear

Without stripping the front timing belt cover how do you know he has the updated oil pump fitted? As many late edition D3’s had the old style oil pump fitted, only sure way is to look.

Depends what year it is after 2008 the pump had been modified but i dont think thats the concern here as even a oil pump failure would not burn holes in the rocker cover manifold, My diagnosis of the failure is based on experience not conjecture.
As the original poster has not replied to this i can only assume he has gone elsewhereor tken it to a garage for a new engine
