Thread: Seized engine in D4 - what are my steps from here?

Yet the newish LR Diesel Ingenium engines still have rediculously long drainage intervals,and problems.

Most manufacturers are at around 15,000Km/12 months,which seems to be the industry standard.

26,000km! No wonder they blow up.

I might be old school by now, I still like 10,000km.

Is the long interval applicable even in arduous conditions (which some manufacturers, wisely, say includes both towing and peak hour conditions for a significant percentage of time in warm conditions etc)? Cheers

For the D2/3/4,ardious is half those distances and times.

We were doing a lot of work with the new synthetic Castrol Refrigeration oils,so we got to know the oil testers pretty well.At the time i had the TD5 D2a,running Castrol engine oil.
Quite a few times i had the engine oil tested,and at 15,000Km,they generally said can be left if you want.I once left it until 20,000Km,as the test at 15,000 came back not bad,and they said it is OK,but a change is needed ASAP.
LR at the time were quoting 20,000Km intervals for the TD5.

What the tester did say is the Disco oil at 15,000Km,was in better condition, than his TD 4.2L Patrol at 3,000Km.

Our D4 was always done at 10,000Km,which is same as every Tojo vehicle i have ever had,although Tojo do say you can go 5,000Km over and it will not affect warranty,and it is written in the service manual.

You sure LR said 20k… that’s not what my old servicing literature states…

10,000km intervals with 20,000k intervals on the secondary oil filter.



ALL metro used vehicles are arduous cycle.

This is what you had previously stated scarry some time back.

I had it tested at 20 000km a couple of times and the comment was it is still OK,but needs changing.

We were doing a lot of work with the newer,in those days,synthetic Castrol refrigeration oils,so i got to know the Castrol guys well.

The TD5 was brilliant - was more than happy with 20,000km oil changes for city use. But wouldn’t run as tight of tolerances as the TDV6 does.

LR only went to 26,000kms or 12 months (which ever came first) for low sulphur content countries. For mod-sulphur content they used to still specify 13,000kms or 6 months max with MY10-11 (3.0).

Not convinced Australia should have been put in the low-sulphur group from MY12 on.

But I do wonder how many 3.0TDV6 that failed doing 12month servicing were doing more than 15,000-20,000kms between services.

You are correct,i will change the other post

The effect of late oil changes is a cumulative thing, so saying that some have failed just after an oil change doesn't mean anything, I'm pretty sure that's not what you were meaning but thought I'd clarify!!

It's obviously the accumulated earlier damage that's at fault

An oil filter that drains back the oil can be an issue though for sure.

As regards extended drain intervals, a lot of this is simply to do with emissions requirements, unfortunately the engine has to take one for the team!

Of course no one factors in the emissions cost of having to build a new engine or car because the old one has failed, due to trying to meet emissions requirements.

The discovery 2 oil filtration system is not to be confused with a normal(any other) car.

Jap diesels were traditionally filthy compared to basically any one else, plenty of (very) late oil changes requiring either removal of the sump, or filling with diesel, running.. Then dropping again due to carbon saturation making the oil like grease.

I've seen a Hilux blow the filter off the block because of clagged oil, that one had plenty of oil pressure but not much flow!

No doubt newer ones are not like this.
