Petrol v6 4lt life expectancy

[kinigo270]

Hi folks,

Still doing some research on the current model v6.

I am after some info on estimated life expectancy for the v6 Hilux. Had a quick look in the forums but couldn't see any posts.

What are some major mechanical items that would need to be changed as it ages, and at what number of kms would you expect this to happen.

Will it outlast the current diesel?

The whole diesel vs petrol thing is doing my head in.

95 percent of my driving is stop and start, short distance from home to bus and the weekend run arounds.
And the odd long distance trip out in the bush.

Cheers,

and yep the 1GRFE V6 is one of toyota's best ever engines

I'd avoid anything with a DPF in it, especially with your driving

Having had the V6 in a 2006 cab chassis from new I can vouch for them being a cracker of an engine. In 10 years we had no issues with it whatsoever, just by the book maintenance. We got 22-25 mpg no matter how or where we drove it, around town or on the highway towing a trailer, always between 22 and 25 mpg (which indicates to me that it is seriously under-stressed).

We now have the diesel in our 2016 4x4, mainly because we couldn't get the V6 in a cab-chassis format any longer.

What you may need to factor into the mix is resale value, when we traded our V6 SCC in for the new truck we found that the diesels were worth a considerable amount more than the V6 as a trade-in and as a straight sale proposition. This may or may not matter to you but it's worth thinking about.

Whether a V6 will outlast the 2.8 diesel is anyone's guess - no-one will know for certain until it's too late for your decision!

My humble suggestion, don't over-think this, drive both around town and out on the freeway and see which you prefer. Either engine should give you many years of reliable service, gone are the days of engines wearing out after 100,000 miles (thank goodness).

V6 cheaper at sale time, means cheaper to buy too though... resale is usually a 2 way thing ...

I've had mine few years now (2nd owner) it's a 07(my08) dual cab auto .. It's just coming up to 195000kms and hasn't missed a beat, no weird noises or anything.
changed the water pump 2years ago not because it was stuffed mechanic said it had a small weep and didn't want me to get stuck.
I use it beach, bush and city

+1 for the water pump, seems to be the only real thing that goes bad. Mine minor leaked for a fair while before I did anything about it (same thinking as richie though, i'd rather replace than have it blow completely while on some beach in middle of nowhere)

How many kms have you done?

[Qwerty]

140k .. it weeped at around 120k from memory.

My mechanic himself drives a v6 hilux (2wd single cab, supercharged, lowered truck sorta thing ... it's nuts) he said it's a common issue but that they don't break / let go, just weep / leak.

he reckons he sees heaps of V6's around with half a million or more km on them.

Quite true for second hand purchases, OP sounded like he was looking at a new buy though. I do recall that the diesel was $7k more than the V6 for a similar body style back in 2006 when I bought mine but I suspect the price differential may have narrowed considerably since then.

Is it the same V6 in the Prado?

Yeah from my knowledge for the new hilux I believe the price is pretty aligned between diesel / petrol. No huge price difference as compared to a few years ago

Great motors, have the v6 in our Prado. 230,000km trouble free so far.
No mechanical issues apart from the idler pulley bearing seezing and throwing the belt

Mines on 175k and no signs of issues yet.

Coolant level has stayed the same for the past 2 years so i don't think the water pump is going anytime soon.

My only dislike with the v6 is its a bit of a gas guzzler which in turn reduces its range.

Not quite, the hilux is the older single VVTi engine, the Prado is the newer dual VVTi version, the basic engine is the same though.

[Qwerty]

Prado has a bit more grunt owing to the dual VVT-i instead of single VVT-i ... in reality the Prado is several hundred kg heavier so apparently the Hilux still has more power to weight.

Would be nice if toyota would put the dual VVT-i variant into the hilux, god knows why they haven't!

[Gulfstream8]

Yep thats right - Hilux gets the Single VVti 1GR-FE V6 and the Prado gets the Dual VVti 1GR-FE.

x2 --- very disappointing Toyota did not upgrade the Hilux to the Dual VVTi or to the Atkinson Cycle 3.5 Lt V6 in the Tacoma.

I did some research on the Dual V's the Single VVTi 1GR-FE V6

While I cannot prove 100% I would have to agree with that the two engines are virtually that same. Gadget from "Underdog Racing USA" who has pulled both engines apart for development believes the Dual VVti on the 1GR-FE is only there to control pollution so as to do away with "Exhaust re-circulation" ---- on the last few years of sales of the Tacomas with the single VVti V6 they had "Exhaust re-circulation" to combat the tough Californian pollution requirements. Its much more engery efficient to control with Dual VVti rather than "Exhaust re-circulation".

As the 1GR-FE for the Tacoma was made in the states it was too hard to retool the factories for the Dual VVti and too expensive to bring in the Dual VVti from Japan as Toyota gets huge subsidies to manufacture in the USA; so it would not have been worth it for as new model was only a few years away.

However the USA FJ Cruiser in the states gets the same Japanese made Dual VVti we do and I presume its due to low sales. This is how Gadget has experience with both the engines.

Sorry I digressed
So essentially both engine are identical and the extra power is really either an ECU program or the fact the Dual VVti has a much better inlet.

Ether way you can easily improve Torque and KW to above and beyond the Dual VVti 1GR-FE V6 with a very simple TRD CAI.

Begs our question though, in the Australian / Oceanic market, why the prado gets the dual and hilux doesn't ... nothing to do with USA factories, both are built in Thailand ... from engines built in Japan (the V6 is i believe built in japan and shipped to thailand for fitting?)

No mechanical issues apart from the idler pulley bearing seezing and throwing the belt

x2 for idler puley issues (no siezing though) ... and that was primarily from smashing it through muddy sility terrible muddy shit when i first bought it. Never again!

Mud can get f*&Ked! *unless i really have to in order to get a decent spot*

The reason I assume would be multifaceted.

Australia has always had a good trading arrangement with Japan and now with the Japanese/Australia Trade agreement its better so Toyota would be looking at the most economical way to provide equipment.

Prado is built in Japan so it would be much easier and cheaper to give the Prado the same Dual VVti to Australia as whats on the factory floor as thats what it sends to all right hand drive countries.

Hilux V6 sales are very small and as you have stated it is made in Thailand so as they are specifically having make the Hilux V6 for a small market I would assume the Single VVti is cheaper thus sending it to Thailand for installation. Plus Australian pollution requirements are not as tough as the rest of the world. So using the Japanese Trade agreement and the cheaper single VVti they can send it to Thailand for installation into our Hilux.

Atkinson 3.5Lt Tacoma V6
At this stage I can only find its being manufactured in the States and the USA Government subsidies would obviously only apply to the American public so this and the US dollar would make it far too expensive to put into our vehicles.

Most vehicles are made up with a very complicated array of parts V's Price/Gov Subsidies or incentives/Trade Agreements plus how what percentage does a manufacturer require of that vehicle to be classed as Made in that country. It's a massive mess and car companies employ specialists to do just that.

An example is the complex web of Trade Agreements and Goverment subsidies Land Rover entered into to be able to build the new Discovery Sport in England and to be able to sell it in countries like Aust with an exchange rate like ours or others would be a university professors wet dream

Just my humble observation ---- but I'm very disappointed Toyota did not upgrade the Petrol engine!

There was speculation that Toyota was working on a 4" stroke and 4" bore low reving high torque 4 cylinder turbo petrol with exceptional efficiency for the new Tacoma. Not sure if that was true but a USA Toyota rep was on record saying Toyota felt the USA public were not ready for it as Toyota USA main sales push was ultimate reliability and they were concerned that most Tacoma owners don't regularly service their Tacomas on time. This would have been a concern for a highly strung 4 cylinder and keeping the Tacoma at the top of reliable trucks in the states.
