    Of course EGT's increase with a trailer on, EGT is your #1 indicator of engine load. More load = higher EGT's.

    I doubt your engine builder has done any analysis on the engine to determine what "overstressed" means and which components are "overstressed". In short he's pulling stuff from thin air.

    #1 i didn't saying the diesel reached petrol EGT's, i was saying that over fueling, like turning up the fuel pump, can lead to higher EGT's in diesels, as aposed to petrols that typicaly get hotter when run lean....

    #2 yes it is obvious that the EGT's will rise when working ie load or trailer, but in the case of the tdi, and its intercooling/cooling/work rate, if you sit on 100km on the highway, flat ground no load, just the truck, the EGT's are quite aceptable....now tow a 1.8tonne trailer, remembering that the manufacturers maximum is 3.5tonne, and the EGT's become unaceptable at 100km in any sort of summer weather...

    #3 dont make assumptions about someone you dont know, this guy races and builds race engines, works in with oil specialists, has been around landrovers more than most of us here, and KNOWS HIS ****... i also think you KNOW your ****...but as i dont compared to the both of you, its pointless being the middle man....

I thought that seeing everything is new was an attractive aspect of the motor. I just replaced the clutch and alternator and that was $1500 worth my injectors need cleaning/replacing the mechanical pump needs servicing/new seals so whats that worth $2-3K it can start to add up. In fact we could be heading to half the cost of a new motor in those couple of items and I am not sure what else it's going to need in the next couple of years? A bottom end rebuild; or new rings at 250,000 kms thats only 12,000kms away. A brand new motor minus the resale of my 300TDI plus the on going maintainace incurred with it. To pull the bottom end down got be a$1K + in that??? This is what I keep pondering about what is economical long term considerations with the car. It is my work vehicle and it serves my needs fantastically it has to be reliable which it is but little bits start needing attention then its a pain work wise as well as extra costs Interested to hear comments

    exactly the same boat i was in when mine died...

    i payed $11000 for mine plus delivery. that was just to the mechanics workshop...i doubt you can get one for less than that, before install. if u can buy 2

    they dont just bolt staright in. the engine mounts need some modding, the intake plenum is different and they use the 300tdi off mine, and there are other small issues, like the turbo exits horizontaly not verticaly, and some of the intercooler plumbing...

    i just hope i get a decent service life out of this engine...

    heres another point for the money i spent i could have probably put in a ls6 + auto create motor and had it engineered...

    i was rushed as it is my DD and i was loosing work, so i didnt even look at isuzu's, and dont know about them.... but they seem to be built proof.

    It goes without saying that the wrong "tune" can kill an engine. What EGT numbers did you get that are unacceptable?

    Serg the cooling systems aren't good enough,none of them are,go back over my posts and every one of them I tell people get the cooling serviced.I get peeved when people start bashing LR's when the problem they have is owner related or a problem that is just as common in other makes when used in the same way.I'm not making excuses but the overstressed rubbish only surfaced when the ZD30 engines started failing and all of a sudden little engines are overstressed,the fact that Tdi's had been around for over a decade didn't count.The tojo's in the pit were factory recalls,defective from new.As I said my defender leaks but at least it left the factory right at like I also said yours gave trouble,it happens but many more haven't.

    the cooling systems arnt adequate when brand new, so no matter how much servicing you do(which i agree with doing) it wont make it better.

    dont take my posts the wrong way, im not here bashing LR's and saying Toyo's or Nissan are tops.... im just bashing LR's

    i have never owned a "car" only LR's, series , Range rover and defender...
    my thoughts have nothing to do with the ZD30 as kicking off the idea. its an overall view looking at history of manufacturing.... they are able to build closer to the line of planned absolecence than they use to be, cars like any material item are turned over way more often than years gone by, thats our westen culture!

    LR has a history of reducing the quality of design at the cost of new tooling. look at the cv, axles hubs etc all have been changed for the worse that would have cost them money to change the tooling........why BOTTOM LINE. ontop of which they have no quality control.

    300tdis may be ok in a disco of def that only gets a couple of adults and a bit of gear, but use them as a work vehicle, LIKE THEY ARE MENT TO BE DESIGNED and they wont last the distance...

    if all your defender does is leaks id be surprised, never had any elec problems? lights, head light switch? gauges?, absolutely no corrosion? cast alloy mirror arms? caps that hold the windscreen frame to bulkhead? no rust in your bulkhead? no back lash in the drive line due to excessive axle/flange wear?

    my def is not the execption.... im not stuck under a rock....

    tell me this if u could choose a 2 ltr 100kw or 3ltr 100kw engine what would you choose?

    Why are you measuring after the turbo?
    Post turbo EGT is a waste of time. Your upstream temperature could be anywhere from 550C to 800C.

    Serg my defender hasn't overheated ever so saying the cooling isn't up to scratch is not right,and it has done some work,the only elect problem I have ever had is the headlight switch that I fixed buying a drivesafe kit,what would I have out of a 2ltre and 3ltre engine,I have both in the drive way right now,I don't have rust,bits don't fall off,I have driveline slap but thats because it has done 410k's so what do you expect.I'm not paying out on you but saying your engine failed because it is 2.5ltres instead of 3.5 doesn't hold water.Tell me which car maker doesn't build cars to the bottom line?.Like I have said a couple of times yours has died,it happens every day.

    yep i know, but when the exhasut company did the install and added the sendor thats where they put it...i have been very busy of late, but will move it to "before" the turbo. im thinking where the 4 outlets go into one?

    any advise?

    Serg, check out ThermoGuard Instruments , Ian is a member here and has a great write up and info on EGT's and where to put Pyrometers etc etc .
