Has anybody here ever replaced an inlet manifold? Asking as mine has a crack in it (drivers side) and was repaired with epoxy a while back. Lasted about a year but has well and truly cracked again.

Now I've taken it to the indie I use and have been quoted over £3k for non gen parts and labour (both inlet manifolds at same time).

This seems a huge amount!

I'm based around Leic way - does anybody know of any garage willing to take on the job? Im also considering doing it myself.....

From what I understand, this is a bigger job than it looks, hence the apparently high price. Got - 2017 SDV8 Autobiography in Loire Blue

Patch it again and get another year out of it ....... 2012 TDV8 Vogue (L322)

you don't say which model you have but mine is a 4.4 TDV8. It is a big job. all the injector cables need to come out. I had mine done (pax side only) for £1600 all in (VAT/Labour/Parts etc.) here are the part numbers etc.

Meant to say It's been flawless since it was done 3 years ago. Be careful they don't damage anything else whilst doing the job. My Thermostat housing was damaged (unbeknownst to me) during this job and caused havoc with my DPF regens for a while. Had to replace thermostat housing etc but again all perfect now. Just did a 1600 mile round trip to the Alps without a flutter.

And good luck finding a replacement thermostat housing in the present JLR parts shortage.... 2012 TDV8 Vogue (L322)

Sounds like they're pricing it out of the workshop, I did mine a while ago, it's an all-day job to do both sides and you only really need to replace any corroded high pressure fuel lines, injector seat washers and hold down bolts, plus EGR gaskets. Not really a driveway job though. Parts cost me around £320 using non-genuine manifolds.

Phoenix - those were my thoughts to be honest. They’re really busy - not sure they need the agro of me asking for the car back every day they’re working on it!

You wouldn’t happen to have a parts list that you’ve mentioned or a link to spares you used?

Any help is greatly received! 2007 Range Rover Vogue 3.6 TDV8

And any specialist tools you can think of….? 2007 Range Rover Vogue 3.6 TDV8

There's nothing 'special' as such, a high lift trolley jack with a good rubber block for lifting the engine, 10mm swivel head ratchet spanner, low range torque wrench if you want to be OCD, if you're at all used to mechanical fasteners, you'll know when it's the 'right' torque! Some brake cleaner and some medium Scotchbrite for cleaning up the mating surfaces, some GP grease, I use it on black rubber gaskets as it helps to form a seal first time - BTW, be careful you don't dislodge the seal as you move it to the rear of the cylinder head. 'technically' you should replace the vac pump seal but some black sealer on the cleaned-up metal gasket will do the job. It's easier if you remove the fan cowl & the fan, 36mm spanner or shifter and a good deadblow hammer will do it. a magnet to keep hold of the injector bleed-off pipe clips will save you hours too.
The hardest part is the engine mount on the Offside, be prepared to spend some time on that, and of course, it's best to do a side at a time so you don't have both engine mounts free!

Have a look at the short charge air hoses on the plenum chamber, if they look shiny, cracked, dry or oily, get some before you start, also have a look at the high pressure fuel lines, if there are any with more than surface corrosion, they'll need replacing.

It'd be wise to set aside two full days as you'll no doubt want to spend some time cleaning the plenum chamber, EGR pipes, covers and other bits & pieces whilst you're in there...

These are the part numbers for the bits I used, LR parts were from Duckworths, others from Fleabay

Injector seat seals x 8 (10) https://www.ebay.co.uk/itm/304703586188
Injector hold down bolts x 16 1387730
Inlet manifolds https://www.ebay.co.uk/itm/233729715539
Leak-off pipe Nitrile 'O' rings x 8 LR019118

The aftermarket manifolds are reasonable quality and have a 12 month warranty - I've used the seller for them several times in the last few years and never had to bother them about warranty claims. Annoyingly, I also paid the full price of £260 when I had to replace mine...

I didn't need to replace any HP fuel lines but there are specific part numbers for each cylinder and the rail link pipes, LR recommend that the injector hold-down plates are also replaced, I only ever replaced them when I was at a dealers and I've replaced many manifolds since with no later issues of injector blow-past.

I think that's everything - time for tea now!

ETA - forgot the ceramic grease for the injectors, not strictly needed but good practice. I used some 'spare' stuff at work, this is the one https://www.ebay.co.uk/itm/362800385959 there's enough in that for about 40-50 injectors!

Thank you so much for your time on this all (Phoenix this is great info!) - albeit you have scared the bejeezus out of me……

Wish me luck… 2007 Range Rover Vogue 3.6 TDV8

By ‘all’ I mean the collective that have contributed help - it is really much appreciated. 2007 Range Rover Vogue 3.6 TDV8

There's nothing especially difficult, it's just a bit long-winded. Don't bother putting the harness back in place until you've done both sides, I'd suggest you start with the nearside bank as there's more room and you'll know what you're doing (but a mirror image) on the offside bank, which has some access issues. Remove and displace more bits rather than work round them, good lighting and bungee cords will help no end, you need to make a choice between working at access height which is easier height-wise but makes the engine lifting harder to access or working at offroad height where you'll need a step or platform (and a bit of dense foam on the slam panel) but the underneath work is easier.

Sounds a bit steep to me?

New gaskets on both sides cost me £800 including parts when I had my 3.6. To do that obviously involves taking both manifolds off, so I can't see why it wouldn't be more than that plus parts.

I believe it took them 11 hours. 2015 Range Rover Autobiography 4.4 SDV8
