Recommended Indy - TDV6 oil leaks

[DiscoJeffster]

So it’s leaking from the front and from the rear. In fact I think there’s more oil on the outside of it than in it. 265,000km. I figure it’s a body off and redo all the cam seals and other stuff that bolts on and can leak. Anyone care to provide their recommendations of Indies? I was going to DIY but just can’t be bothered.

Typical cost to get the body off/on for a standard car with no accessories to deal with?

Cheers.

[kelvo]

My suggestion would be Darren at Aztech 4x4 in Rivervale, Darren is also on here as DazzaTD5. I haven’t used his services yet, but will be in the future.

Have you replaced the oil cooler assembly yet?

[DiscoJeffster]

Have you replaced the oil cooler assembly yet?

No. I have been seeing a few posts of those leaking into the V and coming out front and back of the engine. You suspect that over other seals at this age? Thanks for the tip [emoji106]

[justinc]

It's the first thing I check when seeing any tdv6 with a big oil leak, yes.

[Graeme]

Do they leak from the cooler to housing gasket, the cooler to block seals or from either/both like the 4.4 coolers?

Edit: Originally the 4.4 cooler to housing gasket wasn't a replaceable item but now it's a spare part. Is the V6 cooler to housing gasket now a spare part too?

[DiscoJeffster]

Ah it’s not a big leak volume wise and I’ve previously looked for oil in the V and not found any. I suspect it’s other sources on mine, but I’ll take another look today.

They do seem to be sporting a great rep. Thanks for the tip, perfect location for me too. I look forward to just dropping it off and coming back to perfection.

Where does the oil cooler live?

[justinc]

Where does the oil cooler live?

In the valley

[BradC]

Where does the oil cooler live?

Under the oil filter. More correctly the oil filter housing is part of the "assembly".

[PerthDisco]

Thanks - not needing body off to replace.

The OP should also confirm the oil filter cover o ring is correctly located.

[geoffmc]

I am experiencing the same issue at the moment, so will be interested to hear your findings. So, does the oil cooler crack or fracture as a result of overtightening on the filter cover?

cheers
Geoff

[Graeme]

If the TDV6 oil filter housing/cooler suffers the same fate as the 4.4 TDV8's filter housing/cooler then the gasket between the filter housing and the cooler go hard and the same for the gasket between the assembly and the block. The 4.4 has the added disadvantage in that the assembly sits on top of the EGR cooler so gets extra hot.

I see that cooler/housing gaskets are available for the 2.7 but I haven't spotted any for the 3.0. Furthermore there is an early and a late version of the 3.0 assembly applicable to specific 3.0 versions. Both the 2.7 abd 3.0 have several o-rings between the assembly and the block rather than a single gasket.

Hi DJ

Another LR indie I’ve used is Sovereign Automotive Myaree. Knowledgeable and good service. http://www.sovereignautomotive.com.au/

[DiscoJeffster]

So I had a look today and I don’t believe it’s leaking at the cooler. It’s not leaking heaps, but a small patch after each trip. Some is leaking at the front, the other is the rear drivers side. I suspect possibly the seal where the vacuum pump fits onto the back of the engine - in and around that area. At the front I’m not sure. Might be camshaft seal, could be elsewhere. I’ll just take it in and get it sorted.

[discorevy]

It would be worth mentioning to whichever mechanic you take it to that you recently replaced the cam cover in case it's the gasket.

True. Thankfully I don’t think it’s that as there doesn’t seem to be leaks on that side of the engine.

[discorevy]

I'd forgotten you had done the lh side, still be worth mentioning as the rh side had been done before.
I've done 2 vehicles ( both sides ) in the last 2 weeks and spend the time alternating between getting in to a zen state while willing my fingers to be skinnier , about twice as long with 2 extra joints and dreaming of one day running into the Ford bean counter so I can permanently encase him / her in a heap of their cracked tupperware intake manifolds.
actually that's not fair to tupperware as I think they have a lifetime warranty.
Makes me wonder if Ford delved into the food industry as I also spend a lot of time replacing their parmesan puma driveline components with metal ones. ( they may have used cheddar on the tdv6 crankshafts).

I think Land Rover reliability should be better when there ceases to be anything in the vehicle that has anything to do with FoMoCo

[DiscoJeffster]

Has anyone seen crankcase pressurisation issues with the TDV6 engines? I suspect that might be a factor as I notice a film developing on the plastic cover around the oil filler and on the engine lining. The washer on the oil filler is tight so I don’t suspect that leaking from normal pressure. I am now wondering if PCV is a problem causing leaking and pressure around seals.

Jeff stop caring, just take it in I keep saying to myself

It’s not that. Removed oil air separator and it’s not blocked.
Oil found in the bottom of the v. Only thing is I don’t know if it’s old from previous oil filter changes or oil cooler leak.

[DiscoJeffster]

Leak 1 found. Oil being squirted out of the intake under boost pressure because the clip wasn’t seated home. The joint was opening up under boost. I’d previously replaced the o-ring and it was still leaking. By chance only spotted that the clip wasn’t seating hard behind the tab. Grrrr.

I have cleaned out in the V as much as possible with degreaser and water. We’ll see what it’s like in a week. If it’s back and leaking there then I’d agree, oil cooler.

[Fatso]

I had oil leaks around where the Y piece fits into the intake manifolds , on removing i found the two thick squishy "O" rings on each part of the Y were shot and leaking turbo oil under preasure out and around , replaced these and ok , on reading your post today i went and checked if i had put the bit that you found not replaced properly and sure enough i had done the same thing with the clip missing the Tab . Thanks for posting . :BigThumb:.

[DiscoJeffster]

Confirmed now finally no leak at the intake. Fingers crossed that’s where all the oil at the front has been coming from

If you're lucky it might be where the oil at the back was coming from also.

Keep an eye on that o ring, mine manages to squeeze in between the housing and the clip, exactly where your red square is, then leaks oil. I’ve dodgied up a clip that holds onto the plastic of the housing and fills the gap between the snap steel clip and the throttle body, works for now until I get another o ring, then I’ll try to double them up. I’ve also got to order replacements for the y piece sealing o rings. From your photos, the area around the throttle body is relatively clean. Hope you find the leak.

Only after a big degrease job [emoji106]

I was thinking this morning that I can’t believe the amount of oil I found in the V is spillover from oil changes. Or that it’s still so liquid if it was years old. I think Justinc is right. Leaking cooler - possibly only the o-rings but I think I’ll order a complete unit anyway, change it, and go from there. That’s about the last fix that doesn’t need a body off.

Ive not experienced much spillage at all from oil changes when doing the suctioning method, so i think youre right that its the oil cooler leaking

3 parts away from being hand built...

[DiscoJeffster]

Nissens brand cooler assembly ordered. They’re an OEM manufacturer of cooling system components and presumably are the OEM for Land Rover as they are for PSA and Ford. I expect it will be a fun swap.

[Graeme]

Be very careful not to contaminate the oil passages in the block because the passages after the filter are direct to bearings etc and you don't want rubbish in any bearings!

Same size or larger/more efficient?

[DiscoJeffster]

Same size. It’s an identical replacement.

Graeme, yep, that will be fun. The balance between wanting to clean it all down while it’s out versus the risk of it out. I’ll block the ports with clean rag immediately or something more appropriate when I see what I’m in for.

[justinc]

With the 3.0 it is seemingly impossible to remove /refit the cooler without removing the LH intake manifold.. a small trimming of the intake pipe to aid removal and refitting is necessary. Don't be worried as you will see the y piece ends up further in that side, it is possible to remove plenty of the manifold intake before impacting sealing. Also, the tradition of removing way more parts than the 2.7 engine to do the same task will become painfully obvious...🤬🤬🤬.

Far out. The engineers really need a talking to.

I once had a problem of oil leaking into the V and then running down on to top of bell housing on a 2.7 from the element type filter.
On undoing the filter casing I found that the O ring seal that seals the filter casing had a hole through it and that allowed oil under pressure to leak into the V.
So now I closely check every new O ring when I fit new filter element. (And I then insisted on Mahle or genuine grade filters.)

[geoffmc]

Disco,

I had the same issue on mine, as i cleaned out the throttle housing and noticed a month or so after, there was a spray of oil over the fan and the cowling. I have since re-seated the housing and O Ring and hopefully this has rectified the issue. Ill be checking this weekend and report back.

cheers

Intake clip

[Eric SDV6SE]

Checked mine again last night, clip had popped out from behind the retainer again, oil mist on the top coolant hose and underneath, as well as underside of engine cover. I also checked my manifolds, both still ok. it surprises me how much the plenum moves in relation to the throttle body, even though they're both mounted off the engine. I'm going to order a new retaining clip (if sold separately) along with the o rings and seals, and put a rubber grommet between the plenum and it's mounting bolt off the engine bracket to try to give it some room to move. Adjusted the throttle body slightly so that it lines up better with the plenum but there's not much realignment room- may need to file out the throttle body mounting hole. Also noticed the left y leg seal is getting worse, oil drips into the valley. Minor issues in relation to DJ's oil cooler.

[v8sruleok]

I did this with mine too whilst researching boost leaks, squared up the throttle body by adding washers where the bolt goes thru. Much less likely to leak at the throttle body O-ring now.

[Eric SDV6SE]

Checked again the other day, clip has moved again will need to readjust and add another washer to the spacer. I'm thinking the stainless clip is getting lame.

Interesting. Mine is so tightly wedged in it can’t move. I think maybe the alignment on mine is such that there’s tension between the throttle body and 90 degree bend that it’s holding tightly in place.
