Thread: Recommended Indy - TDV6 oil leaks

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

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.

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.


Intake clip

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 . .

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.

Intake clip

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.
