We are currently reviewing vehicle options and I was wondering if anyone had heard about some serious problems in the Media recently with regard to the Toyota D4D 3.0 diesel Engine in Hilux & Prado.

Apparently the Injector seal leaks & related problems in HiAce, Hilux & Prado possibly known to many owners, have also now been linked to “Clogging of the oil Pickup Screen” & Oil starvation of the engine. This apparently can lead to premature engine failure if not identified and dealt with early. Checking complaints on line with this issue, evidence seems to suggest this has occurred even with the regular service of the engines within authorised service programs, and it is not being picked up before it’s too late within the normal service programs.

Can anyone comment about experiences or knowledge of this issue, particularly with HiLux or Prado? We are looking at either and some other people I have spoken to have said they were aware of problems with the 3.0 D4D in these vehicles as well.

I found another post elsewhere that would seem to confirm that this is definitely a current issue in Europe, with a major customer contact campaign currently underway until August next year on Vehicles as Early as 2006

Would value some feedback prior to making our next purchase.

I wouldn't read into it too much, the problem seem few and far between.

Yes they are doing a recall in Europe and New Zealand but no news here.

Best bet is jump on "Prado Point" or "The New Hilux" forums and have a look ....... proberly the same as the oil issue in the 200 series, funny thing is it's only affected a hand full on the LCOOL forum.

Real life vehicle dedicated forums are the best place to find out information..... if it's not documented on them the chances of it being an issue is near to non existent.

In Europe they have different consumer laws and emission standards so it may of been forced onto Toyota to act.

Stuart I can not even tell you off the top of my head how many d4ds we are running , but it would be over 30 and we have never struck this problem, of bigger concern is water in the fuel killing the fuel pump, ea time this has cost around $9000.

A thread has just started on this over on the New Hilux forum by a new member who has been affected and has a dead motor but nobody else has heard of the issue. There has been a number of faulty injector issues though
With the amount of D4D's on the road I would think that there would of been a lot more noise about it if it was a common problem. It is easy enough to o an inspection with an oil change so can't hurt to check.

yeah I have seen V6s destroy cams/engines. The reason is the oil pickup screen half to 2/3 blocked due to crystalized oil. The cause? Dunno - one Prado I saw was maintained 'by the book' from 40Kkm to 180Kkm - so the screen may have been blocked before 40Kkm - no service records existed on this car (ex-auction) and it was supected most services were skipped.

Prado petrol has a sump inspection plate so it an easy fix/clean. Hilux petrol (mine) doesn't.

Can't comment on diesels, sorry ...

The D4D injector problem is a world-wide problem, and Toyota are reputedly offering extended warranty on the injector seals. No doubt you have to make it obvious you know it's a major worldwide problem, and that Toyota know about it. In some cases, some Toyota dealers are saying it's not a problem.

Engines packing up at 100,000 kms is pretty pathetic, particularly when Toyota brag about build quality. It wasn't so long back the V6 was blowing up, some as little as 200kms on the clock. Toyota were forced to admit that this was a QC problem, and it cost them a lot of money to remedy it.
