Who has had Engine Failure in 120 series

No doubt I will be paying more but I will keep this Prado 6 or 7 years like the last two.

Shit!!! I was thinking 20 years!

Now I am semi retired with no cash flow I was going to drive it around Aussie. You guys have me to scared to start the bloody thing

I'll have the injector values checked when they fit the new ABS brake controller (fitted a new water pump last service). The good thing I have noticed is that it doesn't hardly use any fuel. A recent trip to Victoria and back took only one refill, so the Injectors are not wasting it.

I'll be driving to Brissy and back with an off-road camper in Sept, may drop in on Roo for a chat.

I've just had a new motor put into mine and i'll be lucky if I keep it another 3 yrs

peril no need to panic but you have to remember that injectors are a consumable item in any diesel engine. The big issue was the cost and seemingly short life of the injectors. Plus I guess things could go bang without much or any warning. In the old days the engine would just get rougher and blow black smoke when the injectors needed a service and you could easily have them reconditioned. There was no real rush either you had plenty of time to sort it out.

With the D4D the new coated seats (I believe anyway) should last the life of the injectors and with Denso selling injectors for a fraction of the new Toyota Oz price (as does Rick from NZ if that deal lasts) and Bailey reconditioned injectors the cost isn't as daunting as it was. Good housekeeping is the key. That is keep the inspections up and use quality oil and fuel. If the fuel is likely to be dodgy then fit a pre filter or water trap. Separate threads on here. I'm still working so I have a particular plan for vehicle upgrades that suits me. No doubt that will change with time. I think I have mentioned previously that if I had my way I would still have my old 90 (with the odd mod or 43) and the wife would have something small and fuel efficient for driving around the city. I lost that battle a looooong time ago. I don't even ask the question any more.

Getting off topic with my jabbering but thanks for the insight as to your findings. I sold a perfectly good 90 series in hope a younger car would last longer, I live in hope that the plan was not in vain

I'm a big supporter of clean diesel, I have had some bad fuel in my time. One lot of fuel I got must have been laced with Kero as it made a mess of the bores in my 4Runner. From that it basically cost me $8000.00 in repairs and the rings wouldn't bed. So I traded it for my 90 series which I fed "ONLY" Shell or BP Diesel, no cheep fuel for that girl. I never laid a spanner on her in over 150000kms, traded her for this 120 and already it's bustin' parts. One thing I've also found is parts are RIDICULOUSLY expensive, lucky I have extended warranty.

Currently I live in a small shoe box in Sydney, I cannot do much work until I move into my 4 garage house in Deception Bay. All the Prado has to do is last 6 more months and I'll be in a good position to give it all the lovin' it can handle. (touch wood).

I'll have the injectors tested, that should tide me over I hope.

I put over 170,000km from new on my 90 and it was still going well, no head problems or glow plug problems. If I had kept it I would have probably replaced the head and injectors and glow plugs and then waited another 7 years to do anything on the engine other than services.

thanks retroenduro. Light has always worked and I wait for it to go out. Dad has diesels so knew. I am guessing this is what you mean after a google. Can it fail and appear to be working? Will need to check service records as doesnt ring a bell. Would Toyota check this as part of service

over time the ends of the glo plugs get brittle and can just break off having disastrous results. it wont give you any warning so just make sure you replace them every 100K - i think its in the toyota schedule to do it...can anybody confirm?. And also get good ones, not cheap ones...although the OE ones are silly money.

I do believe a class action sounds good. It would bring Toyota Australia Motor Corporation into account. I had another person, tell me yesterday that he experienced blow by. Toyota in the Adelaide Hills, said they'd fix it for him, $4,000 dollars later he was told the car was ready. Went to pick it up and was told he has engine damage, that will be another $10k. The guy got on the horn to head office, did his nut and was later rung that day by some poor sod in service. As the principle was too gutless to get on the phone. Car was out of warranty, but had been serviced since day one with Toyota, I think he said he'd done 100K. In the end he told them to shove their injectors, to return his money, take out the injectors and he'll pick up the car. He installed his own new injectors & rebuilt his engine being a diesel mechanic. But here again, Toyota's great customer service. Seems like the more you yell and scream, you get your money back. Doesn't seem right! Anyways, getting my Stat Decs on everyone who I come across, want to make sure to the magistrate that I am not an isolated case.

Don't forget this thread. Any update?

Hi Gracie,
I have just encountered a situation where my D4D had Diesel leaking from injectors into the engine sump. This resulted in injection replacement (4 injectors, pipes & washers) at a cost of $4000.
How did you go with your case against Toyota Australia

Ahhh an internal leak, not so common, unless, had somebody been working on it recently? 4k Ouch!
Very interesting.

I trust the injectors were replaced because they were old or close to being out of spec. Although, if they were original then it's probably a good thing that they were changed out.

Hi Dave
Injectors tested prior to removal, Cylinders 1 & 3 were found to be out of specification. decision made to replace with new Denso injectors
I think they were original injectors, motor has only done 141000Km with regular servicing and very easy driving.

The motor was driving very smoothly & I only became concerned when I found a 12mm increase in the upper limit on the Oil level stick, the only other indictor was sometime when cold starting the engine would have slight rough idling ( but this rough idle would disappear once I started driving)

Lucky for you. Mine blew at 73,000km when 2 injectors went out of spec and cracked 2 pistons.

My 2008 Prado D4D died last week with 126000km on the clock. Diesel mechanics in the town I was towed to all concluded that it had "dropped a piston". What was concerning was the fact that the three different mechanics I saw had all had several D4ds in with the same problem in recent months.. According to one there were problems with piston and injector quality with the most common issue being a leak past the injector O ring that led to carbon getting into the oil and blocking the strainer on the oil pump intake leading to engine failure. The mechanic who did the engine rebuilds said that the injectors were held in with an 8mm bolt and its small size meant you couldn't tighten it enough to prevent future problems especially if tightened to Toyota specifications. He rang a diesel engine rebuilder in another town while I was there and he reported that he had 4 Hiluxes with the same problem in a week!! Toyota asked that I return my vehicle to where it had been serviced and I'm now waiting for a diagnosis and hoping that Toyota will assist in the repairs.

This is exactly what happened to my 2007 Prado. Not covered by insurance as not involved in accident. Over $10,000 spent and two injectors replaced. Now having to sell as cant afford to keep.
