Toyota Landcruiser 1VD V8 diesel oil pickup problems

Yack
Thinking logically, a local mechanic only sees relative few such vehicles, and a dealer WILL NEVER admit to any knowledge of such things. So, therefore they are the two most least likely to have any awareness of the problem.

There are many parts in modern vehicle which fail. Nissan Navara timing chain guides, BMW car timing chain guides. From experience extremely thin wall BMW plastic radiator inlet spigots simply break off. 1mm thick wall on a VERY expensive vehicle. Not Surprised Toyota has used plastic in their oil pickups. it too can fail. Bean counting? Hardly a SERVICE item as claimed by the video man. Oh, "I take my sump off at every oil change", RIGHT! and have a stock of oil pickups ready for action. Everyone does don't they?
A very cheap bolt in Dodge Rams, breaks and destroys the engine. That sounds good economy.
Earlier Mitsubishi engines had a little thin bike chain driving ESSENTIAL shafts in the engine, ie, oil pump etc. They flogged out their guides/broke and destroyed the engine.

Standard service check for a Prado for anyone that knows is to check the filter screen for any signs of blockage caused by failing injector seals.

Note, the service schedule for Prado from memory indicates tappet clearances should be checked every 40000km. If this check is performed the fuel injectors need to be removed and the seals replaced so failure is less likely to occur. Problem is dealers don't do it as it is expensive and if they are not meticulously clean and properly prepare the injector seats and keep dirt out of the injectors they can cause expensive problems. So they just listen for tappet noise, no noise then they don't need adjusting but seals don't get replaced and can fail.

When I was travelling I asked a local dealer if I could wait while they serviced the Prado and they said yep no problems. When I took the car in I asked if they could make sure the oil pickup screen was clear. I sat down and a few minutes later the receptionist comes over and says they won't be able to service the car then and there I would have to leave it and pick it up later.

They obviously knew what I was referring too but weren't intitially going to leave the car long enough for the oil to drain away properly so that the could check the filter screen.

Anyone with a D4D should have the screen checked when the oil is changed. Also is a good idea to fit an oil pressure gauge if one is not fitted so that you can keep track of any pressure changes. Amazes me that they put Tachos in cars, temeprature gauges and possibly voltmeters meters but one of the most critical systems in the car doesn't generally have a gauge to monitor it these days and even in most cases the engine management system doesn't keep track of oil pressure. blockage caused by failing injector seal

Amazes me that they put Tachos in cars, temperature gauges and possibly voltmeters meters but one of the most critical systems in the car doesn't generally have a gauge to monitor it these days and even in most cases the engine management system doesn't monitor oil pressure. By the time the oil pressure light comes on at around 3PSI from memory it is to late, if the engine management system monitored oil pressure with regards to engine RPM and temperature it could n when a detect when a blockage is occurring and warn of it.

PS in the Prado the screen can be seen through the oil drain hole, don't know about the 200 series.

Checking oil pressure with a service gauge should give an indication of the state of the screen but with the Prado for instance is a a pain in the bum to access and fit a adapter to check it.

Just watched a you tube video about it worth researching to see if it helps you come up with some answers he has a d4denco website sign behind him. Looks like they still choose to use cheap plastic parts in an engine that gets hot and can ruin or melt them. Anyway it might help you or not.
It's funny as it looks like they made a small plastic sump that collects things that break off the internall of the engine.

Hi Yackandandah,

I viewed the first video 6mths ago & was concerned however in the Jaffa video (250kkm service) he needs to jamb the edge of a screwdriver into the screen to get it to fail. That is a point load designed to make it fail, not a distributed load which the screen it would see under normal use. I don't think he would have broken the screen using just thumb pressure.

Yet to be convinced I need to race out & change mine with 240kkm on my VDJ.

Regards

I have replaced my pick up tube as it was only 30$ plus gasket goo. I did watch the video a while ago and after attempting to inspect pick up for damage and carbon build up, I decided to replace.
It’s impossible to see the screen as it’s located halfway up pick up tube unlike old school screens where you can see them through sump plug hole.
Fairly simple job, as long as you don’t snap the oil level sensor float whilst cleaning off excessive oil.
I had 200+ k kms on engine.
