The Path to Prestige
The concept of the 80 series was the combination of "Advanced" and "Top Quality" features at the highest level. However, the true reason why the 80 series gained worldwide attention was the fact that it able to maintain its original toughness of excellent off-road characteristics while being loyal to the above.
In 1989 regular minor changes were introduced, all in the direction of greater luxury, which led eventually to the evolutionary transformation of the ever-popular 60-series into the new 80-series.
At the time the 60-series was being driven more for leisure or family use, and as a town car, than as an off-road vehicle. Over time the demand increased for more fashionable and passenger car like characteristics.
Post the Overhaul of the Fuel Injection Pump FIP and changing the Injection Nozzles I was eager to gauge the Fuel Efficiency (FE) of the vehicle. Since the Overhaul I have driven the vehicle for an approx distance of 2100 Kms which I think is a good measure for gauging the FE. I have measured the FE on a tank full to tank full basis. Further during this period I did a out station trip of 1062 KMs from Delhi- Jaipur-(off-roading 150kms) Sawai Madhopur- Delhi and the rest was 1 trip Del- Bhiwadi- Neemrana- Delhi (approx 300 Kms) 3 trips Delhi- Bhiwadi- Delhi (approx 190 KMS each) and rest local city driving.
On the Highway run (Jaipur & Sawai Madhopur) I was averaging speeds of 110-130 KMPH and did off-roading of 125-150 kms. This run gave me a FE of 7.96 KM/ Liter.
During the second round of driving I was averaging speeds of 80-90 KMPH and the TLC returned a FE of 9.95 KM/Liter.
Prior to the FIP overhaul the TLC was returning a FE of 7.00-7.50 KM/Liter with the best and worst being 8.35 and 6.90 KM/Liter. Therefore I think that the work has been satisfactorily done, but would still keep an eye out and would base my judgment once I’ve completed 5000 KMS post the overhaul.
Uneven Tyre wear
Another issue that has now cropped up is uneven tyre wear on the rear tyres. As can be seen from the enclosed pictures both the rear tyres are showing signs of uneven wear, which is to say that the rear left has uneven wear on the Left and same for the rear right which is wearing off from the right hand side. I am clueless as to what this issue might be. Have asked around in my friend circle and also on some Toyota Landcruiser Forums. The latter attribute this to low tyre pressure. I generally keep the tyre pressure at 30PSI on all 4 and they say that it should be atleast 38 PSI. My friends and also the workshop manager at Lakozy Toyota attribute this to the suspension and particularly to the suspension bushes. Have got the alignment and balancing of the vehicle checked regularly. Still working out the cause of this problem and hope to find a solution soon. These tyres were bought by me IInd hand and the previous owner had used them for an approx of 5K kms and since then I’ve used them for 20K Kms. The manufacturing date on the tyres are 3rd quarter of 2009.
Hoping to find a solution soon.

Rear Right Tyre
Went to the workshop a couple of days back and they have manage to source the Nozzles for the fuel Pump. I was fearing the if the nozzles were not available locally then the vehicle would have to be in the workshop for atleast the next few weeks as the new nozzles would have to be ordered from abroad. The fuel pump too has also been Overhauled and I expect that I should be getting the vehicle back within a couple of days.
They had just received the pump back from the Pump Repair guy and I managed to click some pictures. Pardon me the bad quality of the pictures but these were the only ones I could manage from my phone camera. The make of the pump (though not visible in the pictures) is Denso.
Fuel Pump after Overhaul
Barely after driving the vehicle for a little less than 18K Kms after getting the Diesel Fuel Pump re-calibration done, I feel that it needs to be done again.
The reason for this is as follows
Firstly the FE of the vehicle has gone down drastically. Earlier (before the RE-CALIBRATION) the TLC used to give me a FE of 8.5, city driving, to sometimes even 9.5-9.75 on the highways) . Now the FE is barely 7-7.25 KMPH.
Second reason is that earlier under hard acceleration there used to be very little to no black smoke from the exhaust. Now even on idle there is black smoke emitting from the vehicle. This can clearly be seen from the naked eye. On hard acceleration the vehicle smokes like a chimney. So this can’t be good. Under idle, when one stands at the back of the vehicle, you can feel the unburnt diesel on your eyes.
So these two reasons were enough for me to send the vehicle for the re calibration. Gave it yesterday at Lakozy Toyota at Okhla Industrial Area. They said that I can expect the vehicle back in a weeks time. Will try to keep the developments posted on the blog.
The ODO meter now reads 1292XX Kms.
PS. Uploading this post from my Android device. If I seem to get the hang of it, I will try to be more regular with uploads.
Post the previous service interval, I had taken the vehicle for an outstation trip to Tordi, Rajasthan for some dune bashing and off-road fun. This was a three day trip and the TLC performed remarkably well during the entire trip both on and off-road.
However there were some parts that conked off during/ after the trip and I had to replace them after I came back to Delhi. The following was the job done
110295 kms on November 22, 2010
Power Steering Pump replaced
Brake Master Cylinder replaced
Rear Differential Seal Replaced
Oil Pressure Switch (This was not working since the day I bought the vehicle)
Power Steering Oil
Power Steering Change
Brake Master Cylinder Change
Front Guard Setting
As many would know that the 1st off-road vehicle that I had bought and restored was a Mahindra & Mahindra MM550. Threads are all over this blog under the MM550 section.
Anyways the new owner that I sold the vehicle to, has done a complete restoration himself and practically rebuild the vehicle from all over again.
I recently received an email from him with pictures and a brief writeup on the work that he’s done on the vehicle. So the first thing that I thought was to share it with everyone.
Thanks a lot to the new owner for sharing these pictures and giving me permission to share it with the community.

The other day I was reading a review of the LandCruiser and found this one to be really interesting. So I though that it would be nice post it on my blog so that I could share it with everyone.
