  1. I had the first head changed by the dealer here and was just told it had failed but didn’t think to get a look at it to establish HOW it had gone. This time did it all myself and there were 5 cracks visible to the naked eye. Three were between valves and two running from valves to injectors. Strangely there was very little evidence of damage to the gasket though and what there was looked very recent (slightly discoloured but otherwise clean). I’ve located a 2nd hand shroud in the S.Island so just negotiating how to get it sent up and I’ll blank off where the original intercooler was to
  2. Rebuilt my 300tdi with it’s 3rd head in 200k km and now looking at why it should need a new head with every cam belt . . . . . My current thinking is it might be in need of better cooling - truck has both a full width intercooler and aircon condenser sitting in front of the radiator and when the viscous fan was swapped out for a Kenlow the fan shroud was removed. When the head was being done I gave the radiator a chemical flush, made sure the intercooler was clear and fitted a new a/c condenser. I also fitted a new thermostat and checked the fan switches on and off both thermostatically
  3. I guess I was just surprised at the manufacturing tolerances. The difference between a 1 & zero hole appears to be .39mm which in old money is about 15thou - seems pretty relaxed & I wonder what BMW, Merc, Toyota etc work to and whether the same applies to modern J/LR engines
  4. May be (probably) a dumb question but the ad says 200tdi, is this the same for the 300? If so, will pick one up next time I’m in UK
  5. Had exactly this problem on my 300tdi and in the end fitted two tiny green LEDs between and just above the gauges to replace the standard dash lamp. I did look at changing to the TD5 cluster but then I saw the price my fix cost about two bucks from AliExpress
  6. That could make sense if the “standard” gasket was 1 hole - then you’d have the opportunity to skim the block 3 times (not sure why you would though) however; my block definitely hasn’t ever been skimmed yet it has a 2 hole gasket . . . .
  7. OK so I understand 1, 2, 3 & no hole gaskets relate to accommodating piston protrusion from the block but can anyone enlighten me as to WHY Land Rover felt it necessary to make engines of differing dimensions? When I look back to my 1970’s basic apprentice training hand filing chunks of steel into true cubes I find it hard to believe that 90s technology couldn’t precisely engineer a standard block or piston. Am I missing something here?
  8. Thanks for all the feedback and info. In the end I elected to pass on the Isuzu engine and as when I got the head off the bores etc all looked good, have sourced a new head, gaskets, bolts, core plugs, water pump, thermostat and expansion tank/cap to rebuild the original engine. I’m also taking this opportunity to change the cam belt and the radiator is away being checked & cleaned at the moment. Hopefully she’ll be back together next weekend. The head itself had cracks between the valves on 1 & 2 and to the injector on 2 and there is evidence of some gasket leakage between 2 &
  9. The 4JJ1 Dmax is indeed a common rail engine so this mightn’t be readily achievable. The last thing I want is to introduce any electrickery to the car. Hopefully I’ll get the verdict on the 300 Motor later today - certainly the quickest and most straightforward fix!
  10. Good point but she was built to NZ spec and as far as I am aware the only real change was to fit a km speedo
  11. I had Disco seats for a while but although comfortable on the posterior found them too high and I felt a bit hunched up under the wheel. When I made the subframes I fabricated hinges into the rear mounts and used M8 bolts with plastic handles (from some old roof bars) on the front passenger side so quite a quick job to access the battery by tipping the seat back. I also fitted a couple of short cables to an Anderson plug on the seat box to make for easy charging. I still use the subframes but moved to a pair of Autotecnica bucket seats some time ago. These are super comfortable and real
  12. I’ve owned the vehicle from new. I bought it for export in UK, used it there for 11 months for visits and shipped it to the Middle East and on to NZ. It has now traveled about 210k km, none of it really very hard working. The head gasket first went at around 100k and the head had to be skimmed for refitting now it’s gone again but this time was pretty dramatic. Temperature rose VERY suddenly rose going up a fairly long, winding hill with a light dinghy trailer on the back and she blew coolant before the temperature dropped quickly back to normal and remained there. To all intents it appea
  13. Sadly the head has gone on my 97CSW (again!) and I’m left with the option of reusing that motor with a new head, water pump etc or to swap out for a Dmax 3.0T 4JJ1 with just 35k km. I appreciate this option means stripping the “new” engine of all the computer parafanalia and going mechanical but just wondering if anyone has or knows of someone who has done this swap? I’ve always been in favour of keeping the old girl as original as possible but having to change head gaskets more often than cam belts is a pain and I have to admit, a 35-odd% increase in power is quite appealing so any cons
  14. Problem solved: It was the telltale in the instrument panel. My car has one light covering both indicators so I'm guessing this has a couple of diodes that should block any cross feed. Whatever the device it must have failed and that allowed it bridge both directions. Taking the wires out from the plug was a major so as a temporary fix I've just cut the feeds and will solder them back when I get a new binnacle cluster. Tracking this down was a real challenge for me so I hope some other unfortunate might benefit from sharing. Cheers, Alan
