PETER,
I've got a 1992 GQ 4.2diesel nearly 260K on it, never used any oil or water in the 4 yrs ive had it !.I change oil every 5K &filters at 10K.Extractors and a good 2.5" exhaust are definately worth the money !
Mine doesnt look like stopping for many Ks yet.Great 4wds.Email me at patrol692001@yahoo.com ,if you want any other info on GQs or mods.
CHEERS MIKE

Mate at work bought one at 340000km's runs like new.
500000 to 600000km's is not unheard of. Very strong motor the 4.2 diesel. The petrol is also a very long liver. Heard they shear the same block? Is that true.

Thanks for the info,sound pretty bullet proof to me,can't complain about that sort of reliability.
As far petrol and diesel sharing the same engine blocks I'm not to sure.

I can point you at 4 that have 520,000+ on them, without a spanner to them.

Mine has 260,000 on it and has just had a turbo thrown on 10,000 ago...

Peter, I ran an 88 diesel GQ (Maverick, actually) for 12 years and 250,000 without a problem anywhere. Engine just as good as the day I bought it. All I ever replaced was a clutch slave cyl, a rear axle oil seal and a fan viscous coupling (use an aftermarket VL Commodore replacement, much cheaper). Great machine, more rugged than the plastickey GU I now own.
Early in its life, found that Shell gearbox oil caused a slight whine in the gearbox about 90k, but BP Multigear 85-90 fixed all that, and was quiet right up till I sold it.

Hi Peter

We've got an 89 GQ 4.2L diesel with 260K on the clock and about to get quite a few more. When we were looking for one last year, we saw numerous in great shape with 300 - 400 and even 500K on the clock. The one with over 500K was probably the best of the lot mechanically (verified by a NRMA check), however for the same price we choose to go for less miles (it also had an impressive service history). Apparently gearboxes can go after 250K (depending upon how they've been driven). Back window frames rust out, as can the floor and check for cracks under battery and firewall. Look at the interior wear and tear, bodywork (for obvious respraying) and get underneath and have a good poke around and you'll soon see if it's been well maintained.

Good luck!

Hi Peter,
Re rust, for what it's worth, the DX Patrol had fixed rear side windows, which did not have the rust problems of the sliding windows in the better-specced ST.
Also, not sure of the differences, but with the Maverick version, Ford had a 6-year no-rust warranty. I noticed that the doors and seams everywhere were filled with a waxy substance, which must have contributed to the rust-free status, but can't say if this was different to the Nissan version. The bog-standard '88 Maverick I had was rust-free after 12 years, even after beach work (I used to extensively hose out the underside after a beach run, tho). Ford dropped the Maverick in the early '90's, so all would be pretty old by now. The resale was a bit lower on the Ford, making it better s/h value.
