Well!

I had a 4.2 GU before. Did about 190,000K's in it. Nice, but bleep it was SLOW! Even after squeezing about 30KW more from it by blueprinting, bigger exhaust and pump recalibration.

The 3.0 that I have now has a bigger exhaust, D-tronic and better filters, is MUCH nicer in power delivery (except for take-offs where the 4.2 kicks it's arse!) but I'm finding that people may be having cylinder-head problems, turbo shagging faults and such.

Currently, The NSW Police at Cooma have two Patrols that have had stuffed engines, my mate has a Patrol with 140,000K's on it with blown cylinders 1 and 2 (and he's religious about his servicing), the work Patrol has had upgrade has a blown turbo. Something is missing with the reliability eh?

I had a 3.0 Gu

July 2000 Build

drove 99270 in it prior to trading in on a New Prado

Problems i had:

Seized Idler Pulley / A/C Compressor (also took out the Fan belt and Fan) Warranty

As above but this time water pump dead, alternator and a few other bits. No Warranty $4500 fix, no parts had to wait 2 weeks

Clutch gone at 55,000 (went Heavy Duty then) No Warranty $1500 fix - 1 week

Cracked Flywheel - replaced Warranty - 1.5 weeks to fix

Just prior to trade, Leaking water pipe (cracked weld) 2 weeks to get part, traded it in before the parts arrived.

My brother is on Gearbox number 3, Engine Number 2, AC and Idler number 3, has also done a few air flow sensors, had his turbo rebuilt etc.

YIKES!!!

RUN FOR THE HILLS!

My clutch is fine, but the gear box is always SLOW to sync between 2,3 and 4. I never use 5th below 80 cause the engine speed is fine and 5th is a weak point in any design.

The engines seem to be running far to close to distruction for my likeing. I may need to get a V8 conversion if the thing does go south.

We did a clutch for a mates 4.2 a few months ago, $650 was the deal, with a heavy duty Bendex jobby.
