Thread: D4 SDV6 dead engine - what next?

More issues with my D4's actuator and related issues ... the vacuum hoses were replaced, somewhat urgently. I never saw the parts - part of the bundle of taped up tubes was a metal pipe, with a hairline crack ... probably there from brand new, as the issues has been intermittent while towing.

My son rang me Tuesday week ago, saying that for his scanning job in Karratha, they won't let his petrol Prado onto the site. He has lots of high tech equipment, which he cannot fly it to there, so he has to drive it, from Melbourne. So sure I said, take the Disco ... so suddenly the Disco repair job was urgent. They got the parts delivered Monday morning, and at 2 pm it was ready. So I took it straight to my son's place, I cleaned the car, he started packing it. He left Tuesday morning with his wife, and he'd drop her off in Adelaide, they'b book a hotel and bought an airline ticket. Then he rings me on Tuesday, still in Melbourne - the car is on low power mode, warning lights!

So bad news for me ... I went and test drove a 2nd hand 200 Series, and was ready to buy it from a dealer. 98k Sahara, seemed in good nick, 2019. I'd buy it for him to have a vehicle, and I'll do W.A. in that. Then he rings me, and says they've fixed the Disco. A vacuum line had kinked after pushing the turbo ... they then unbent the kink, ensured it couldn't happen again, and off my son went. I told the dealer I wouldn't buy it ... still not sure about a 200.

So my son leaves Adelaide at around 11 am, and he makes Penong - past Ceduna, that day, Wednesday, I think about 750 km that day. Next day the Thursday he drives to Kalgoorlie - 1300 km. Friday he's off on both bitumen and dirt and he's ringing me saying how the Disco is so fantastic it levels everything, and he loves the engine, and he's finished his fourth talking book. The phone connected straight away via bluetooth and speakers are fabulous he says. He stops to help some grey nomads finish replacing a tyre, and later he again stops to help a chap with an overheating old Patrol, and back he goes to the previous fuel stop and buys some radiator fluid for the Patrol guy. He makes another 1,000 km that Friday, and stays in Newman (the Pilbara area). 2 pm he is in his digs in Karratha, having test flown his new high tech drone, which was almost taken down by a huge eagle three hours out from Newman.

He wants to buy the Disco, I'm not sure if its wise to sell it to him ... I need a spare one really.

I quite like the 300 series, but they are overpriced IMO. The Patrol is fabulous I reckon and I think great value. No oil issues or turbos to worry about. It eats the juice if one uses its glorious motor. I'm tempted. It's not easy finding a good spare Disco.

My son's D4 seems now to have a sticking primary turbo at idle. We have yet to watch what happens when the ignition is switched on and off to see if it is indeed sticking and if so to work at freeing it, but I can't help thinking that it might be a vacuum hose issue.

My son's 3.0 D4 is all better. The young mechanic hadn't refitted the vent tube for the several solenoids which is meant to connect to the air-box, instead replacing the T and the line to the air-box via the engine mount solenoid with a 1:1 joiner to link all solenoid vents together and leaving the engine mount solenoid disconnected. The lack of the ability to vent meant that the CSOV was being held open, causing the various faults.

Sigh. Good work sorting it all.

I had already swapped the CSOV solenoid once but with 3 available swapped it again to no avail, but found vacuum in the vent tube while idling. Cleared faults again then with the vent tube disconnected, went for another run to find that it behaved, so returned to the house to check the vent system fully only to find it a closed system.
