Hi Forumites.

Want to run something past you to see if there is an answer out there somewhere.

I have a GXL 2006 Landcruiser 100, Non Turbo, which has just clocked over 100000kms.

There is a smell coming through the airconditioning vents, various descriptions of rotten mango or a natural gas smell.

It started off occurring after I had been cruising at about 100kms an hour for a while and then eased off on the accelerator. The waft would come through. Now it mainly occurs when sitting on 100kms an hour in fifth gear and then drop it back to fourth gear and push it, ie to overtake a truck.

Fuel economy is poor as well, with a lot of black smoke from the exhaust. I just had the EGR closed off, which seemed to fix the smoke but not the fuel economy. (Average about 17 - 18 ltrs per 100km, sitting on 100kms. Roof rack, spare wheel carrier, 2 inch lift). Recently travelled with a friend who had the same vehicle, with a similar setup, carrying more gear and he was getting 2 ltrs better fuel economy)

Vehicle has been into the local Toyota Dealer, who removed the whole aircon assembly, disinfected it and replaced the evaporator. They promptly charged me nearly $2000.00 for the privilege, however the smell is still there. I have also put several cans of Glen 20 through the recirc vents.

Both batteries have been replaced.

I recently replaced my heater core and got a very strange smell for a week or so until it was "run in". I noticed there was a problem when I was leaking radiator fluid inside the cab....and with leaking I mean a small drop every couple of hours. I was lucky to spot the leak so maybe you have something like that going on?

A sweet sickly sort of smell is quite often a sign of a coolant leak, makes you wonder what sort of job the stealer did if they didn't find it having had the entire HVAC system apart, or did they?
Have a good look at the evaporator drain which is a little rubber hose coming out of the firewall on the passengers side in the engine compartment, any moisture coming out should be clear and have no taste or smell. If it is discoloured or tastes sweet then you have a coolant tleak.
Very small coolant leaks may not show up in the drain as the airflow dries them off leaving only the smell. From you description yours has a high pressure leak that only happens when the engine is working hard or hotter than normal.
Can't help with the fuel consumption but they don't sound excessive for a well loaded 1hz travelling at 100k.

Airconditioner is leaking gas slowly. They put the smell in to distinquish the leak. Had the same in my 80 series. Get the A/C guy to check the reciever under the dash. Smells like something died in the vent (spent ages looking and disiffectng with no results) A/C was still working OK. Took it to the A/Conditioning guy and he had the leak in minutes.

Roof racks will definitely give you worse economy, no doubt about it.

Low tyre pressures, add a bit more. ( some places you have no choice)

Labouring diesel motors, give a bit more.
Your right foot has a big effect on economy.

Would it not be better to get Tojo put on a Dyno, at a diesel specialist, rather than a dealer, as dealers don't care how much they charge.

Winding back and advancing the pump, will probably do the trick,, but leave that to the specialists,
