What are these engines like for longevity? They have a variable somethingorother turbo nozzle.. Basically has anyone any experience with them? Are they solid?

They have a tendency to chew turbo's. Price for a new one is $5000 NZ. At the moment, nobody makes an aftermarket turbo or can repair them, it's throw away and buy new. Other than that, a great motor.

It's a diesel so it's bound to be shite.

[dieselboy]

Thats a bit worrying!

Diesel engines are always better than Petrol, fact! Theyre simpler and make more power.

If that is the case, why don't F1 cars have diesel engines in them?

Because Diesel engines are not about high revving power and consequently do not rev to 20,000 RPM. Diesel engines normally produce more torque than HP which is really the opposite of what a F1 engine would require. As an example, there is a pickup which produces about 2000lb/f of torque at around 3000rpm which is way more than any luxury sports car would ever produce.

Petrol engines have a higher power to weight ratio, Diesel engines produce more torque at lower rev's

[shokenore]

and electric motors are better than both.

They have iffy injector seals from new, so they leak diesel into the sump and the oil gets diluted and they blow themselves to bits.

Have changed 2 complete motors this year. Toyota will cough up the £6K odd for a new short motor if you make a fuss and do your research.

If you get one change the injectors seals to the new type and they are all good.

Wasn't overly impressed with how full of crap the intakes get from the EGR, for a 5 year old engines, and they are stupidly electronic based, so much so when replacing injectors, we had to get each injectors serial number programmed into the ECU to get it run properly. Not the sort of motor you can fix in the middle of the desert.

But you said they are 'always better'; make your mind up!

Nice one Tony, thanks. Out of curiosity how did you even program in the serial numbers? That's actually pretty daft?

No idea, we took it to a Toyota dealer to input the numbers after re-build.

Each injector is 'tuned' the ECU needs to know its settings to make it run 100%

Its not just Toyota, most motors are like this now, its the only way they can meet the latest emissions standards.

£300 a pop too, one was re-conned, other 3 needed to be new. On a 55 Reg LC.

Madness.

How can a diesel engine be pedantic?
