About to do this as well :shock: as I have coolant in the valley.
Ordered a kit from http://www.idparts.com/oil-cooler-se...42-p-5146.html
Looking into new bolts if I need them.

So basically water can get into the crank case and ruin the engine.... is that the case with the whole "oil cooler seal saga"

No, not usually the case. The seal (either oil side or coolant side) blow out & leak into the valley.
In my case its the coolant. This morning when I reversed up my drive way I had a very noticeable trail of coolant 4 metres long.
It's been leaking for some time but only a 20 cent size puddle overnight until now, It was like it when I did my last NT trip with caravan in tow (6000km).

I new this day was coming :(

HI Guys

i just done an oil and filter change today on my 3.0 diesel and after filling and starting i noticed a knocking sound i hadnt noticed before as this the first change ive done since owning it(seems to go away once warmed up), i used Nulon fully synthetic oil 5w 30 oil and ryco filter. and apon a little research i found a TSB on this stating a replacement on No.1 crank bearing. :( (assuming previous owner used heavier oil to cover up noise)
Has anyone else had this issue ?
Im not sure what to do, to use heavier oil , to fix or get rid of car
feeling pretty peeved and let down .

cheers for any help

Change your filter to a Mann brand. HU821x

is that it clarky that easy ? are they picky with the type of filter or something

A click or a knock? It is very typical to have injector rattle and that comes and goes. If you do a bearing it won't ever go away.
