Good Afternoon  all,

 

I have a technical question regarding a Toyota Prado 2013 TX. Vehicle had been running like a dream and during the middl eof winter would go into limp mode for about 3-4 days. I immediately booked it in earlier for next service. Garage called to say the injectors needed replacing (183’000km) insurance approved the injectors. less than 1000km later the car billowed smoke, lost compression I pulled over immediately. oil and diesel mixture filled one of the injector covers and the engine bay

long and the short. Piston is cracked and has a hole burnt into it. Insurance says they will not pay as it is as a result of previous faulty injectors. Garage says the new injectors are fine and in working order.

1. The car never smoked before, fuel consumption was perfect and there was no ‘diesel knock’ observed

2. Can a piston deteriorate over time. or is an event like this a sudden and catastrophic failure

3. What recourse do I have with insurance company

4. Can someone guide me to a suitable technical expert to get advise.

 

Regards,

High Gary,
was the injectors replaced by RMCI approved work shop? get them to provide you with a technical report with copy of there RMCI registration certificate despite having 183000 Km is quite a bit, but as a rule the pistons should last longer than that.
Submit this to the insurer and send a complaint to the relevant insurance Ambuds man. I just wonder if the guys that fitted the new injectors did not maybe dropped something into the injector hole and it maybe moved from the center of the piston to the side and the when it hit the head it pushed through the piston.
Is it an extended warranty that you have, and read the fine notes.
But it is typically of insurance they will gladly take your monthly premium
and when it comes a claim the will do there best not to pay.
Medical aids are just as bad these day.
