Hair line crack on the inlet manifold! When Mikey put his smoke machine on my car, he was still hesitant! Then he started stripping bits off my engine to reveal the manifold!
It was hard to see at first, but then all was revealed, smoke from the manifold!
He replaced both sides, now pulls my caravan with ease!
Call him, I’m sure he’ll point you in the right direction!


Best regards

David,

Thanks for the advice. I had a good investigation of the inlet manifolds on the right, the side where I'm getting my boost pressure error. There is some soot on that side so it looks a bit suspicious. I started spraying soapy water on the area and the crack became obvious, even at tickover.

I'm very please pd to find this as at least I now know what to fix. I'm going to try and repair it initially, but I'll probably end up replacing the manifold in a while.

Many thanks.

Here's some photos if it helps anyone:

Underside of engine cover sooty on one side:



Sooty mess around the fuel rail and one of the injector fuel delivery pipes



Bubbling to soapy water on the plastic inlet manifold (not very clear on the photo but very obvious even at idle)



Very pleased I've found this. Thanks everyone.

I had the same, seems to becoming more regular now...

I cleaned it all up and then used JB Weld Plasticweld on the crack with a covering of Tigerseal for good measure... Just to see if it would hold
I am sure I will need to replace at some point but a couple of months in and still all good with no faults  2008 TDV8 Vogue SE

Just a sucker for big bills!!!

I've got some JB Weld and I'm going to have a go at it when I get the chance. I know this will probably only be temporary but I'll see how it goes.

Reading previous posts, it generally seems to be the right side which fails.

Plastic weld it? Soldering iron and add material? Cheers

Likely to be too thin to plastic weld, ending-up with a hole instead of a crack.

My plan is the clean the area up, roughen with and paper and degrease with alcohol. I'm going to seal/ overlay the crack with JB Weld reinforced epoxy.

Fingers crossed.

I'm fully prepared to replace the manifold in the future if necessary.

try some CT1 if that doest work then and its too thin to weld. Cheers

Ok. So at the weeken, I attacked my intake manifold crack. Dirt and soot removed with WD40, the electrical contact cleaner to degrease. JB Weld applied liberally over the crack. Left for 24h to cure.

On idle, the crack no longer leaks and no bubbling is seen with soapy water. In use, I have no errors and that includes towing a horse trailer up some big hills.

I'm not sure how long this repair will last but initial results look positive.

The best thing to "cold" weld plastic is liquid and powder nail acrylic. My other arf is a nail tech and I tried her nail stuff on some cracked motorbike fairings with great results. Since then any broken plastic bits get the treatment its stronger than original when done.
It can also be easily shaped and sanded if needed. 2007 Vogue TDV8 in Zermatt Silver with Charcoal

Exactly the same crack has appeared on my valve cover at about 240.000 km. The sooty mess around the fuel rail and one of the injector fuel delivery pipes as per pictures above.
The vehicle goes into a limp mode with "Engine fault" message and sound.

As per previous posts, I am thinking to apply JB Weld. After 1 year can anyone report if the repair with JB Weld still last?
Did you applied JB Weld when the engine was warmed up or cold?

My JB Weld repair lasted about 2 weeks then the fault returned and it started going in to limp mode again.

I bit the bullet and replaced the manifold/ rocker cover

My repair lasted about 2K miles. Consensus seems to be that replacement is the only real solution

Replacement is not option for me just yet as it is a big job.
Recovering A/C refrigerant, removing injectors and raising up the engine because of 4th injector. After that replacement rocker cover itself, gasket, new fuel rails, refrigerant back etc...
Why Land Rover has not done a recall it is their engeneering fault !?
I will apply JB Weld with some plastic welding first. I hope for more luck.
