Ah ok.

My observation is that the gasket goes between 50 and 80k miles. Yours in that range, just. Confirms my armchair theory anyway!

I've not heard of one going twice.

I like your simple idea of extra silicone.

So maybe a thorough job you won't have to worry about a 2nd time? Hopefully.

Greg Cheers, Greg

I'd like to read the TSB beforehand. I found an exploded diagram of the cooler referencing the new gasket and I suspect that the picture was lifted from the TSB. However a revised gasket from that used to assemble the cooler originally should have caused the cooler assy to get a new number which hasn't occurred so perhaps nothing has been done other than to make the gasket purchasable, which implies that the problem will re-occur if nothing else has changed, including where the cooler was replaced with an identical part.

Loctite 518 is for metal to metal face sealing when one or both components are aluminium so the faces might get a smear of that during reassembly and fitting.

Cheers Greg 🤔🤔 mines on 70,000 but , time will tell.
I fully intend to tackle the job myself when it does start leaking and will be using Hylomar Blue on the joints and gaskets.
I will take my time doing the job, changing the mystery sensor and the O rings at the same time and giving the plenum manifold, etc a really good clean before re- assembling. I am just hoping it gets me through my forthcoming holiday trip without problems.

The TSB states that the gasket between the oil filter and the oil cooler fails due to heat damage. Funny that this damage occurs on every 4.4 at around the same age and that LR thought fit to add the repair procedure to the 4.4 in all vehicles in which the 4.4 is fitted. The gaskets are obviously unsuitable.

New gaskets now fitted, topped with RTC silicone then left overnight after fitting to cure before subjecting to oil and coolant. The original gaskets weren't protruding and given the deep groove in which they locate, I'm not surprised that they compress only a little then harden allowing them to leak over time. Oil on top of the filter housing indicated that at least the cooler gasket had failed.

Silicone intake hoses 70mm ID x 60mm long were fitted in place of the original early style, re-using the original clamps. 55 mm long would have allowed the intake to readily drop into place instead of being a tight squeeze.

Considering that the filter housing / oil cooler gaskets on the 3.6 TDV8 and the 2.7/3.0 TDV6 don't appear to fail yet are located in the same area of the engine, iI suspect that the 4.4's fail because the filter housing sits atop the EGR cooler.

OK, so took mine into the local indy to get the squeal and tick noise sorted and asked them to look at the oil leak that arrived the other week (I did the rubber rings myself months ago, so i know its not that)

Been told that its the oil cooler that needs replacing at around £1400. Others are saying around £1k or less on here, so seems very expensive, is it worth putting this to another indy as he said that there is no gasket for it???

How easy is it to get to and replace the gasket. I checked that it had no oil in the coolant so not sure as its the first time i have used them

Firstly I'd not use the indy you mention, if he's unaware there are infact gaskets (2) for the oil cooler, I'd probably not trust his ability to do the work itself.

I recently changed both gaskets on mine myself (I did have oil in my coolant, although not much as it turned out) the gaskets are cheap, I'd assess the job difficulty as 5/10 for an averagely skilled home mechanic, no special tools and just be methodical.

It depends on whether it is just the gaskets leaking, highly likely, mine were flattened, slighly shrunk and quite brittle (94k miles) or whether the aluminium cooler itself has cracked and needs replacing, unlikely.

SinbadRose,
JCW is correct, it is very unlikely that the cooler itself hase crac and is leaking. get some competent mekanic get this two gaskets from Duckworth Dan and you are set. if I remember correctly gaskets are 15-20 pounds.

just picked it up. The ticking seems to have gone, needs new belts (screeching noise). May get those done. Just need to find the diagrams regarding the oil cooler location/getting at it. Will take a blast through the wiki as well.

Cheers guys, seems not all Indy are the same, need to find one in the northwest.

Out of interest, what was their diagnosis / fix for the ticking? (assume you mean engine ticking?)

It was the idler and the spring had stretched, not ticking anyway. Will sort the screech out with new belts i am told, but defo looking at doing the cooler with someone else

Anyone got picks etc as a how to do this, will look through more posts, sure i have seen this on one of them.

The indy may have fixed oil cooler leaks before the extra gasket was made available which necessitated the whole assembly be replaced and doesn't know that the intermediate gasket is now available.
