inlet manifold cracked..the hits keep coming... just sharing the pain...

[gotaflat]

ok,

so besides a list of issues already being fixes (Bluetooth, lower control arms - gearbox to be done asap, at service today the RH inlet manifold is now cracks... (315,000kms so its done its job I guess..)

[bawl]

Assume the left had in near its used by date (or is that the car all together??)

[Oohsam]

Jeez, that is some bad luck.
I dont think its common for inlet manifolds to have a used by date....cracked? How the heck did it crack?

Edit - i just read your list.
Control arms are not a big deal at all, I wouldn't consider that a major issue.
Transmission service, same, no big deal.
Bluetooth - meh!

bluetooth - I thinks its a new head unit as it incorporated - trying to work out whats happening there
Gearbox is rebuild [bawl] 7.5k apparently [bigsad]

inlet manifold - is common enough - I have had good luck getting this far...again apparently. so $1,800
control arms (lower) $1,600 (I should do myself really)

Perhaps while it is apart at those kms do oil cooler as well but not sure if similar beast to 2.7 unit.

Oh gearbox rebuild. ouch. ok my bad.

Inlet manifold - I just did some research, didn't realise they were plastic. looks labour intensive to replace.

Control arms $1,600 ?
That is ridicoulsy expensive.

The question is, are you happy to go after market?
All four are selling the lower control arms for $220 each. Its not alot of work todo them yourself, you could knock them over in half a day.
There is tons of online videos on how to do them.

If you just want to do the rear bushes, I have a jig for pushing out and in on the car. If you want to burrow.

[gotaflat]

Yep - and I want to do it...that half a day is the problem....[bighmmm]

Thanks the offer - you managed to do ok? I read that replacing the arms is the way to go?

Really time is my issue.

It funny I am thinking buying another D4 [bigwhistle]

Not for me - no aftermarket pattern parts!

Even genuine changed at dealer is less than $1100

Youd think that someone would come up with alloy or carbon manifolds by now....

Its another addition to the crankshaft/gearbox lottery we D3/D4 owners are playing.

MY11 (built 12.2010) D4 SDV6SE with 197000km and still on original manifolds and crankshaft.

crankshaft = motor out and new one? (not really a re build option?) looking at options when that happens... SD6 or TD6 motor? apparently 3.0 motors v hard to get but the 2.7 (ford territory no Probs and cheap to move over)

I’m waiting to find out if replacement manifolds split. My first side was done at 160,000km so I guess in another 50,000km I’ll find out (not lol).

Body off motor out. Replace crankshaft. Motor can be rebuilt, usually the conrod next to the offending main bearing is replaced as well new set of main and big end bearings . New forged crank is around Aud 5k i believe.

Depends on the damage of course. New 3.0l crate short motor is around AUD 18-20K but then you need to add fitting time. Reusing existing turboes and exhaust. But I havent checked in detail. 2.7s are a bit cheaper.

I also understand same motor is fitted to some Jaguars, they dont break cranks or manifolds, so to me could be a power:weight issue with the D4.

Would love to know if a SCV6 petrol is a direct drop in replacement, would have to swap out fuel tank as well of course...

[Stuart02]

Lower control arms $700 ish fitted by an Indie?

Reasonably easy. Took a morning and the bushes are cheap.

B all SC V6s sold in Aus so local 2nd hand supply will be the main issue I guess.. even inc Jags ....numbers will be v low. So OS engine SC supply will be the focus or a new motor🤤

Should be a drop in re g box and mounts albeit for all the necessary changes to ecu(s)...wiring..fuel system ...exhausts...etc etc. I also doubt it can be dropped in from the top.. you can't get a hand down either side of the motor..so def body off.

Mmm...looks far too difficult a swap to me!!

I’m waiting to find out if replacement manifolds split. My first side was done at 160,000km so I guess in another 50,000km I’ll find out (not lol).My son Justin and I compared the latest RH manifold with the original MY10 while changing his and found extra thickness in various areas and more webbing in various places, being obvious strength improvements including along the line where Justin's had split.

[INter674]

Are the manifolds cast in two and welded together or single piece moulded/printed?

I noted the replacement coolant pipes for the D4 SC are single piece moulded or printed even, and not 2 piece joined mouldings anymore. Hopefully this removes the join/seam weak point where the pipes commonly split and leak.

Indy - Factory I believe.

They wouldn’t be genuine parts fitted......

Indie here around $1400 genuine,including wheel alignment,dealer about double[bigsad]

Both sides.

Likely are genuine. Dealers have been doing the R&R service for a while. Where they remove yours, fit a refurbished OEM set and then yours get refurbished for the next vehicle.

There is always something to learn.[thumbsupbig]

OK,i was talking new,not R&R.

If going R&R,the customer should be told......

My Indie also recently said they have been having some success lately with another type of bush,but seniors disease came along and i have forgotten the type[bigsad][biggrin]
They were just doing a few as a trial.
They have used other brands before,but with no success.Always OEM.

You are luckier than I. My MY13 SDV6 cracked the RH inlet manifold on a recent trip. We travelled 300km in cripple mode before shedding $1650 to an indie to change the manifold. Total kms to date 195,000.

Always OEM on those bushes for sure.
Everything else is a compromise of NVH and articulation.
Some are rigid enough to cause failures as are starting to occur.

Regarding crankshafts; diesel Jaguars do break them, because they have the same bad design. From my research, the "engineers" that designed the motor either forgot to put anti rotation tags on the main bearings, or decided that using crush would be enough to stop them rotating. At a random time, usually when it is working hard, a main bearing moves enough to block off the oil supply to that bearing, which soon seizes and crankshaft breaks. There are a few sites on the web devoted to this problem; South Africa being one.

As I understand it, you do not need to replace the crankshaft, just the main bearings with tabs and a suitably modified cap. This might be done without pulling the motor.

If you catch it in time. Usually too late, so its new crank and conrod(s) next to the affected bearing(s) but its definitely a motor out job to replace the crank, as the flywheel has to come off as well.

Jags are not nearly as heavy and dont do offroading so are less likely to fail. Poor assembly technique or incorrect main cap bolt preload excluded of course.
