Toyota Land Cruiser Prado Diesel Problems
Toyota Prado: Carbon build up
Toyota did have a spate of diesel engine failures some years ago when it was discovered that the fuel injector seals were leaking and letting fuel into the oil stream.
Sludge would build up on the oil pickup and eventually it be blocked and the engine would lose oil pressure. As you say the pickup can be inspected through the oil drain hole, so you should be able to see if there is a problem there. It is worthwhile changing the injector seals every 45,000 km.
What's a fuel efficient SUV on the market?
I don’t believe that what you want is out there, and can only reiterate past advice, buy a Patrol/Pajero/Prado/LandCruiser.
Pajero Sport vs Prado diesel - which is better?
The Pajero is a rugged vehicle that is very good on-road and off, it is roomy, safe and well equipped, while the Prado is a large, reliable, and tough seven-seater. It’s very comfortable, but the diesel’s performance is lacklustre. It’s hard to beat the Pajero.
Diesel Particulate Filter clogging in HiLux, Prado and Fortuner?
There are quite a few reports of problems with the dpf clogging on the latest 2.8-litre diesel, but a Toyota spokesman told us there is currently no service campaign or recall related to the Diesel Particulate Filter (DPF) on any of the three vehicles you reference.
Prado diesel engine problems
One possibility that has affected the Toyota diesel in the past is fuel leaking past the fuel-injector seals and contaminating the oil causing a build-up of sludge that eventually blocks the oil pick-up and starves the engine of oil. It's a long shot, but a possible explanation.
Toyota Prado engine seized
It would seem likely that the oil pickup has become blocked, starving the engine of oil. That's a problem with the turbo-diesel engine, caused by fuel leaking past the seal on the fuel injectors and contaminating the oil. The cracked dashboard is also a common problem. If you feel strongly about it you could approach Toyota with a request for a refund of the cost of repairs.
Replaced Prado seals before recall
If they’ve been changed I see no need to do it again. It’s unfortunate that you have replaced them before Toyota contacted you, but it’s done and I don't think you’ve got any comeback on the company now.
Prado engine seizures
If the engine hasn't sustained any damage then I would keep it. But having been warned about the problem I would be very careful about the servicing going forward. The fuel-injector seals are meant to be replaced every 40,000 km service and it's crucial that they are. If they're not fuel can leak into the oil and carbon deposits can develop. The problem is that the carbon can ultimately block the oil pickup in the sump, which is what can cause your engine to seize. If you do decide to keep the Prado have your mechanic check the oil pick-up to make sure there isn't anything that could lead to blockages in the future.
Prado diesel engine failure concern
The affected models were built between June 2004 and October 2007, so you should be wary of buying a 2005 model. There shouldn’t be a problem if the car has been serviced correctly and the fuel-injector seals have been changed as they are supposed to be, so check for a service record. If there isn’t one, or you would like to be sure about the car you’re buying have a mechanic drop the sump and inspect the oil pickup for an accumulation of carbon.
Toyota Prado: Fuel injector issue
It's not unusual for them to have injector issues, which usually shows up by heavy knocking when the engine is cold and is fixed by replacing the injectors. If it only occurs on a slope, however, I would be making sure it isn't an oil pickup problem, and I would have the oil pickup in the sump checked to make sure it isn't partially blocked.
