The shut-off problem has now been fixed and the problem was what I suspected, a missing bush on the diesel pump's shut off actuator.

FYI, here's a video I took in the engine bay of the GQ to find the shut-off problem.

Zantus congratulations, I phoned the the day before you bought it. Was still arranging to get to EC and she was gone. For the price advertised it was a bargain. :thumbup:

Thanks Jacque, but I will be putting in about R10K-15K without really doing any modification, just a lot of small things that needed attention and I'm slowly working through a long list.

My only worry is that I hope I can keep it when all that repairs are done and I don't need to allocate the money invested to something else, because even with all the issues, it's a really great vehicle :woo:

Good day to ask for an update :thumbup:

Got her back from the mechanic today after week.

The folowing work was done:
-The rear crank oil seal replaced
-Flywheel skimmed
-Clutch re-lined
-Oil filters and oil
-Diesel filter
-Air filter
-Cooling system flushed...the one mounting bolt on the thermostat housing is about to break, so it was left in tact and will be tackled next week when a bolt removal expert is in the area to assist, in case it does break off.
-Rear diff flushed and filled with the correct grade of LSD oil.
-General service check-up and adjustments/lubrication where needed.

Last weekend I took it to local playground and tried it on a few obstacle. Fully aware that it is an excellent overlanding car and not as suited to trails as my 4.5GU, the old girl did very well. Here's a video I compiled of the GoPro footage I took on Sunday.

I still need do something about the knocking body mounts, but the engine mounts are actually still ok and not damaged as I thought.....cannot say the same of the one on my GU :doh:

I have another can of Tectyl I will be emptying on the Patrol, taking me to about R500 in Tectyl on it so far.....since the bodywork wasn't the best job around, I want to give it the best chance of preventing the development of rust soon.

I will be giving the wheels a layer or two of paint. Someone painted the wheels without removing the wheel weights, and that just freaks me out!

Lastly it needs a really good valet...along with a well cared for engine and drive train, I like the interior of a vehicle to be spotlessly clean .

Hi Zantus what is Tectyl? Do you paint this onto the Trol?

There's some info on it. It prevents rust and I've used it on the body seams and all the usual places rust tends to develope.

The right buyer came along today and the old girl is gone again :rolleyes:

Pity I couldn't keep it, but the finances were needed for another project.
