Oil Leak 3.0L D4 - Oil cooler and filter assembly -should it have a hole here!

The seal compound is very compatible with the coolant. Its heat and time thats taken to it. 7 years for an elastomer is pretty good.

The comment about the seal sitting flush with the housing is again, heat set, and expected.

Tombie The evidence is not adding up, to purchase this 2014 build LR I traded a 2005 Toyota Hilux and a 2009 Volvo XC60 T6 which I personally had maintained and serviced. Considerable parts had been replaced on both vehicles as preventive maintenance measures, at no time did either vehicle display evidence of oil and water seals deteriorating. Both vehicles did not leak a drop of oil or coolant during their years of use.

If this is normal situation for LR owners I am disappointed.[bighmmm]

I’m pretty sure seals and orings are common tech across all makes. Car manufacturers don’t produce these as much as they don’t produce coolant and oils.

YouTube has plenty of destroyed engines in other makes from catastrophic and premature oil cooler failure but there is only some evidence after a very long life the Disco oil cooler starts to deteriorate but no evidence of one causing a complete failure.

You may have a bad one but generally these car are not known for leaks of any description with rare exceptions.

Seals,O rings,gaskets,etc, are made by numerous different manufacturers with numerous different qualities.

I go along with Gray's post anyday.

After 30yrs of running a fleet of jap vehicles and 20yrs of LR's,there is definitely a huge difference in the quality of seals,gaskets, and o rings.

Its pretty obvious some manufacturers use better quality products than others.

Even in our game,when rebuilding refrigeration compressers,we find a huge difference in seal,o ring and gasket qualities.

Just my 2 cents worth from actual experience.

Some of the worlds best elastomer manufacturers are based on Italy and UK.

Those who understand sealing surface finishes and tolerances etc have LRs that don’t leak [emoji3]

Something isn’t right if a coolant has started decomposing an elastomer in an engine.

I’d say someone has mixed something in or used an additive outside of spec.
