Your best option is to get it diagnosed and scanned.

Many grey market vigos came with an exhaust gas recirculation system. This is required in countries with emission control regulations. The system actually send some of the exhaust gas back into the engine chamber to burn off some of the noxious chemicals. The problem is that there is increased carbon deposits in the engine, which over time can build up to levels that cause reduced performance, poor idling and poor acceleration. Coupled with our poor diesel, well, the problem could be compounded.

The vehicles from TTTL did not have this system because T&T has no such emission control regulations. So these just spew out fumes but the engine was a lot cleaner over time as no exhaust gas was introduced to build up the carbon.

This can be one issue.

Another could be a fouled fuel system.

Yet another issue could be the injectors need servicing or worst case the rails need to be replaced.

And it could be none of those too.

A scan with the Toyota techstream software will pick up the issues.... I am not sure about other diagnostic software, but techstream will run the system checks to identify the sources and the issues.

Let us know what you eventually find out as it'll be good to learn and educate the masses with similar vehicles.

Oh yes. And if you have black deposits around the exhaust and the exhaust is black and cloudy chances are it's an issue with the EGR.

@ Kronik

How are the DBA rotors working out in the Hilux? I'm organising to go that way week after next so some feedback would be nice as you should have had some run time on them.

Soot buildup is not good for the variable turbo
The carbon buildup can cause the vanes/fins which rotate to stick causing power issues

Worst case the motor controller which provides power to the actuator to move the vanes can burnout when the vanes stick and motor is binding.

Good. That's encouraging. I'm gonna put on the DBA on but not using the OEM pads. Gonna put on aftermarket but I cant remember the name right now. Just need to get smtgh that does not warp.

Changed front (10mm allen key helps) and rear diff oil with a mix of
-Mobil 1 Gear LS 75w90
-Valvoline 80w90 Gear oil Limited Slip and
-Total Quartz TM 80w90 (not limited slip)
cause I forgot the requirements and bought non limited slip gear oil and had to use what I had on my shelf. I now have extra quarts of total gear oil that I have to figure out how to use (Might look into using amsoil slip lock to make this oil viable in my rear diff next time)

Half a bottle of Power Service Diesel Kleen to handle injectors.

Greased the driveshafts as i had to wade through some water in El Socorro South this week.

Changed cabin air filter; don't leave it in there like myself for about 40000kms.

TOTAL Cost for 100000km service parts so far:
gear oil: $400
Fuel filter: $180
Fuel additive: $70
Cabin Filter: $200

$850 :)

On the stock tyres (255/70/R15), there is just enough space for me to crawl under the vehicle and work on it. Still a bit tough though. I have a Pennzoil Fluid Transfer Pump (bought online) which helps in the process.

The fluid didn't look too bad after 65000Kms, less metal debris on the magnets than the first time the fluid was changed; to be expected as the parts are now worn in. There were still some visibly reflective fine metal flakes (bronze coloured).

I did mine last at 120,000 by a transmission guy who had a lift and drill powered pump.

It was pretty much pristine. Previous change was done by Tttl.

So recently I started to experience brake judder. It happens when the brakes get hot; and I only experienced it after having to cross 8 humps twice between Fyzabad and Santa Flora while giving the brakes a hard time. I've experienced slight pulsing before but nothing this prominent

Currently have 96000km on the original brake pads and counting... There is still some life left in it... But I'm considering changing them early or taking a scouring pad to the surface

Never heard of that before. Care to explain a bit more on what that is and what it feels like?

Essentially the brakes are normal when cold and warm... But if I keep pouring heat into them (using them aggressively)they will start to judder.

I'm applying the same pedal pressure, but the feeling of deceleration is pulsing; the hotter it gets, the worse it gets. Pedal does not pulse but the feeling of deceleration does. If I continue using the brakes it gets worse and I will start feeling it through the steering wheel.

I don't feel this any other time except when there are a lot of humps in fairly quick succession (200-400m apart; 8 or more); or nearing the end of a Maracas beach run.

When the brakes cool down all this is gone and it's back to normal unless I repeat the conditions that created it.

I normally don't use a lot of brakes... But I still drive pretty fast.

Change it for what... This issue only comes up when I give them hell.

I plan to use it for quite a while still... When I change brake pads I'll let you know how it goes.
