Arthur, I know my engine never ingested any water, at least under my ownership and prior to me buying it was a BFC vehicle from Tennant Ck/Alice Springs.

As I said, JC has had a number of 300Tdi's do this and they all came from the same range of VIN's, only their consequences were worse.

All we could come up with was incorrect machining (everything checks out on my engine) or a bad batch of bearings with poor assembly.
They exhibit almost every failure mode I've read of.

I've experienced cavitation erosion of shells in race motors, that does similar things, small pits all over the surface, but these bearings also had marks of incorrect assembly, oil or grease marks behind the shell on most of them which distorted the shell, and which explain the stress fractures across the face of the overlay.

BTW, the rest of the shells were worse.
The only reason I can think that my crank kept going round and round without any damage was thanks to the stupid exxy oil I ran.

BTW, the mains were fine, damage was limited to the rods.

So am I correct to assume the 300tdi mains and big ends can be changed with the engine in the vehicle? Mine's at 244000 km and has a 2 year old oil pump, relief valve and spring etc, the VDO gauge seems to indicate it runs at relief pressure mostly but when hot from towing the pressure at idle seems a little low. Bearings seem cheap enough.
Mind you I might try putting a supplementary earth on the sender today.

And that's expensive and for not much more I can have a new 2.8. All depends upon whether it's really necessary to recondition I guess.

If your worried about it simply replace the bigends and headgasket,there would be next to no wear at those K's on the other componants.As Rick has said it seems only a small number of Tdi's within a certain VIN range have bigend problems,faulty material or manufacturing of those bearings me thinks.

$8000 seems pretty cheap for the whole package. What are you allowing for in that amount?

Totay I fitted a supplementary earth on the VDO sender. Oil pressure hot (not towing mind you) at idle was 8 to 10 psi (if it's accurate).
Think at 250000 km I maybe should do the bearings if in fact I can do it with the engine in the vehicle.

Creative accounting - how else ?

These are rough figures :

Motor, Large radiator, large intercooler, HD clutch, aircon adaptor, Mantek snorkel + shipping door to door = 6,300 pounds = $ 9300. Customs and GST will be around $ 1000

Fitting + 2000. Total = 12,300

I'm subtracting 2k for the sale of the existing motor and (this is the creative bit) also 2k for the work I would need to do to the engine to make it good for a 4 year overland trip. Because I need to pay in Sterling, rather than Oz $, that's a very big plus also.

So total now comes to $ 8,300. Does that sound reasonable ?

I think you are underestimating customs and GST.

IIRC duty will be ~15%, and GST is 10%.

Ok so you are counting on $2000 real dollars for the sale of your tdi and $2000 mythical dollars that you would have spent on the tdi if you keep it instead.......sounds like you are really just trying to justify it to yourself......haha.

$2000 for the install may be tight. You will need to mod your exhaust. Customize engine/chassis mounts. Sort out the fuel line conections. Sort the spigot bush etc etc etc. If you don't already have a 3 inch exhaust you should with the 2.8.

Have you found out how much bigger the rad and cooler are and how they mount? Does your truck have a/c? If so will these new coolers work in with the a/c condensor and elec fan?

Regarding the intake, u may need to borrow the odd part or2 from your tdi...like the plenum

Also expecting $2000 for an engine that needs $2000 of work is a bit unrealistic.

6,300 pounds is around 9728 aud today but probably cost you 10,000 if look at real rate you will get inc. charges.

i believe import duty (?) is 5% and gst 10% but one of them was calculated on the other so you are better off using say 16% to cover them off. i was looking at an excavator from japan and the cost starts out cheap but then it just keeps climbing.

and then there is all the stuff you just don't include coz you try to convince yourself it's doable and she'll be right.

and then look at your time to arrange it all and take car from here to there etc - that's time you could have been earning a quid (opportunity cost) so being realistic you should consider it.

how do the sums stack up selling your vehicle as is and getting a td5 defender? hard to believe the figures would preclude this option with the $ outlay you are considering. you might put $15k into your vehicle just for the motor and bits but unlikely when you come to sell it this will be reflected in the price.

but these aren't just financial considerations, obviously a personal choice and if you go ahead hope it is everything you are expecting.
