There is a post around some where? Where some one put a Db meter in an Isuzu and then a 300tdi, the difference was negligible. The vast majority can’t tell the difference between an Isuzu and a 300tdi unless told, this includes LR mechanics.

I think that in the latter model defenders, TD5 etc do have some or much better insulation compared to a couple of patches of waste cotton and a bit of carpet on the floor.

personally, after having owned both Isuzu and a 300tdi there is very little difference noise wise. drivability with the Isuzu is way ahead of the 300 tdi. Large sand dunes are a problem for an Isuzu but that’s all.
The only shake noise problem I would say is idle when cold, there seems to be no high idle for a cold motor. The way the motor can shake about can be alarming, but this is easily fixed by turning up the idle or fitting a manual throttle, which is a good move.

I've posted this before somewhere too, but honestly at 100km/h with the same BFG mudders I was running with the V8, there is very little extra noise now with the 4BD1. Of course the gearing is a little higher but still, I am not at all unhappy with the changeover in all aspects.

Turbo and 15psi boost helps in soft sand...

My engines important bits are made from metal and not plastic, little things, like the oil filter.

And the inlet manifold

I bought myself one of these a few months ago



I started to do all sorts of tests, wrote them down & promptly lost the note.
One stastic I do recall is that the Isuzu @ 100klm/hr was as noisy/ quiet? as my commodore with the radio at a level I need to hear OK.
The other was the Isuzu was noisier at Idle than 80klm/hr.
I might take it to the Vic AULRO show & shine next weekend & con some into going for a drive in thier Landies, as my Isuzu has sound insulation.

where puma owners are starting to ask if their landy will be around in 15-20 years time. series and suzi owners are asking if theirs will be round in another 15-20 years time.

Isuzu owners wonder whether their vehicle will still be driving after said owner has departed life. Rijidij proves this it is a distinct possibility:

On the noise topic, I have an 89 model and seems much quiter than the ealier 4BD1's. Even quieter than a 300 tdi. What are the differences? If you dont belive me ask rovercare, he has driven it.

Yep, same with my '88, and significantly more quiet than my '85 was.
