The mechanic has had quite a few stuffed 3ltrs already, much more than the 2.7, they can only put it down to the service interval. Oh and yes how painful will be every time you need to change the rear timing belt, body off!
No the engine life issue is not due to the cracked manifold, perhaps the sieced 3.0 thread may have been a better place to mention the service interval.
Its not meant to be body off to change the fuel pump belt on the 3.0 according to the WSM.
Dumb question but can one do a visual check for a cracked manifold without to much dissassembly?
From the looks of the pics it looks like you only need to remove the engine noise cover.If there are cracks you will see the ooze in the pics I would say.

Even when Kevin at Rovertech showed me the cracks I could not see the manifolds, let alone the crack! They are in below all of the pipes and injectors and stuff and not easy to see unless you know what you are looking at. To get at them everything has to be removed from the engine bay, batteries, air box and everything else so the car looks very sad and sorry for itself. It is a very big job, hence the cost.
One of the points of my post and many decent close up pictures, including putting a coin in the cracks, especially the last one with the two Manifolds in the same place you would find them on the Engine was to show everyone exactly where to look.
Of course in my case I did not drive around with the problem, which is why My left one is so much cleaner than the right one which came from another vehicle where the owner had continued driving it for gawd knows how long.
Once I had seen the Right one and so knew exactly where to look, i wanted to see if mine had the same but on the right side.
So I started by pulling off the Engines Noise cover. That alone was enough to give me my first clue because it had quite a bit of Oil on it's Grey foam covered underside just behind the hole for the Oil Filler cap. This could have come from the cap however the area just behind the cap did not have oil for about 3 inches.
I can only Imagine the mess that must have been on the underside of the other owners Vehicle.
I did not have to move any wiring or pipework, although I did have to push back the edge of some foam to see the area quite clearly as it is on top as shown in my pictures and sure enough, although neatly closed at that time, there was the hairline crack quite easily visible. So it is definatley worth checking yourself IMHO
Of course changing the Manifolds is quite huge job requiring loads of stuff to be removed. It took My chap two days who has done a few.
On another note, continuing the 2.7 V 3.0 problems discussion, last week I encountered a new problem when my 3.0 sport sprang a Massive oil leak at the rate of about 1 Litre per 3 Minutes.
I was lucky to catch this before the sump was emptied, although it did need 5 litres adding afterwards.
The cause turned out to be the front Crankshaft oil seal.
It had not failed in the usual way but had actually popped out completely by quite a way.

The seal is not expensive, but it ruined the cam belt and was not easy to replace requiring special alignment tools etc.
What is even more annoying is that this seal fits into the Oil Pump housing that one earlier 2.7's is a known problem for cracking causing a new uprated part fitted as standard to all 3.0 engines.
However although My mechanic has never seen this happen on the earlier part, it seems it is not uncommon on the Later one.
it must have offered clues if you caught it?
smell? smoke?

In other words have LR now addressed these issues (cracked manifolds and secondary turbo drain pipe issues) or is it on going? If he could clarify for each issue individually it would be helpful to newer D4 owners.

I'll ask the question, has there been a design change with the manifold design.Quote:

It's funny how L/R are going back to single turbos in the D5, perhaps they have learnt something about longevity of that secondary turbo.
