Mad Man

Hey John,

your not wrong, your right; I don't reckon an oil leak on the turbo feed would've killed me - just my engine. You are also quite right that in light of current world and domestic issues my engine could be considered to be small cookies - but I don't ever remember stating anything to the contry.

Still thanks for taking time out from the big issues to share your two cents with me on this thread. I'm sure there are plenty of other threads on this forum which would also benifit from your balanced view.

As for the reason I'm still posting; that's because I still want to find out what the critical thresholds for a TD5 engine are (fluid temp, EGT, Oil pressure, Transfere box temp). Why? So I can put these values in to my Mad Man EMS unit to alert me should a malfunction occur.

So if anyone knows these thresholds or want's to share an opinion on them please feel free, afterall this was the question I raised in my original post. If not then that's fine too but please can we try and keep this on topic?

Thanks.

My Mad Man settings are quite conservative:

EGT - 650C
Oil Pressure - 1 bar
Transfer box - 90C
Coolant - 110C

Do you have the coolant level detector fitted as well? It's a must on the Td5!

Oh, and I always let the landy idle until the EGT is down to 160-170 before switching off :)

Thanks Naks just what I was after.

I've not fitted the coolant level sensors (screws) yet but it's all wired up for them - just have to get a moment or two. I intend to fit these pretty low in the header tank - My coolant doesn't seem to stay at the 'full' level but finds a level about 10mm lower and seems happy there - if I put more in it regresses to this level anyway. I figure I'll mount the sensor abot 10mm below this.

Oil P and transfer box T values sound appropriate - ever have many high T alarmes on the box?

The 650 C fot the EGT is a concern though. I've noticed that I can reach this in about 15 to 20 seconds of hard acceleration and relatively easily on a steepish hill in 5th without labouring the engine. In fact I have my alarm at 720 (the default it came with) and over the last few days have noticed that I set it off regularly. I think the re-map I have is a bit fuel rich. Time to change my driving style! I have been told in the past that 750 is the design limit for the TD5 but havn't had that verified.

Anyway, I have some values to start with there and I'll see how it goes.

Thanks again.

Nope, but then again I haven't been doing much offroad driving lately :(

I'm quite conservative, I plan to keep this landy for at least 20yrs :angel:

The general conscensus in SA is that the Td5 can run for limited periods at 720C max. Extended periods at this temp will cause irreversible damage to the engine. Most Td5 owners here set theirs to 650C.

We have only seen this once on the Puma - fully loaded SWAMBO decided to tackle a long uphill climb in 6th. When the alarm went off, she dropped a gear and the temp went down by 50C+ :eek:

Jeez, I drop from 4th to 5th and knock about 100 C off.... Like I said though - time to change the driving style.

I'm needing help and suggestions how to fit the Auto Tranmission temp sensor. The addaptor provided by Land Online is too big for the sump and too small for the filler plug.

Help Please.

Not what you want to hear, but the local expert says best option is to weld an as near as horizontal as possible nut at the bottom rear of the sump and connect to that

Naks,

Have you noticed any distinct difference in the EGT with and without the BAS remap loaded? I assume the temp fluctuation descibed above was with the BAS remap?

Cheers,

Lou

Hi Lou,

The 'incident' above was with the OEM map. As soon as I switch to the BAS map, the EGTs are *much* lower, by the order of 30-60C.

The BAS map results in lower EGTs because:
- engine is now operating more efficiently
- EGR is permanently closed

Since the remap I have fitted an Alisport intercooler, and EGTs came down a further 20-30C. I have also removed the cat's innards and seen a further decrease in EGTs, but only slightly.

To give you an idea, the last stretch home is on a flat road with 60kmh limit - with speed cameras, so I always drive at 60kmh on the speedo. On the factory map, EGTs are at 330-340C. With the BAS remap, EGTs are at 270-280C.

One thing I forgot to mention about the BAS map is that over the 2 years/30,000km that I have been running it, it has paid itself off in terms of fuel savings. :D
