I'll let you know what I find when I get into my 4BD1T. Head gasket is leaking (it blows bubbles in coolant) and it smokes at idle (suspected stretched ring lands).Quote:

Does the 2.8 have any bottom end improvements over the 200/300tdi?Quote:

I've never heard of the deck 'settling' in service like that as the machinist claimed, but I'm not an authority either.
Forged vs cast crank, better rod design and cap retention (split/cracked caps vs traditional machined caps, better bolts) and supposedly slightly reinforced block with better coolant flow, but not sure what's been done there.Quote:

From a timing/cam drive POV the pulleys are cast and machined, not pressed tin and the belt is strengthened/reinforced, but everyone just uses the Tdi one as it doesn't seem to exist in the Dayco system outside Sth America.
Pistons use a different chamber, etc but don't know if there's anything structurally different than the German Kolbenschmidt pistons of the Tdi.
Santiago from Argentina (SG1 on here) ditched his (modified?) TD5 for an HS2.8 and hasn't looked back.
Serg overfilled the crankcase with oil and it ran on, how can you assertion it's a crap engine from that, Dougal?
I still think iload engine and auto would make a reasonable conversion
We had a 300tdi defender do a runaway on a trip. He went up that sandune like a 350 chev on go go juice!!!
Fortunately for him he knew what it was doing and jamed on the anchors near the top and stalled it in gear. Drove it home without the turbo.
I do respect what your saying about the Nissan 3 litre. But surely if it was only a tuning issue Nissan would have flashed uprated fuel maps at regular service intervals - or am I missing something.
From my talkings it's an issue with the oil 'sprayers'? Cooling the underside of the cylinder head.
Have to admit I've looked up a bit on the tgv, quite impressive actually. If I had a defender thats the motor I'd like. As for the hse, I have to admit the power puts a smile on my dial :)
The vp44 ecu isn't flashable. You need to physically remove and replace chips to alter the tune. Since nissan have never admitted to a problem, why would they offer a fix?Quote:
