The Rambler( W.A.)
After coming back from my annual trip up north I encountered some talk about the new (not so new anymore) V8Toyota landcruisers having problems with injectors needing replacement at very low mileage--50-100000kms. due to inaddequate filtration.I actually spoke to one guy who had problems with his ute before 100000km and spoke to another fitter who works in the mines and said they had one go before 50000.I am not a v8 owner but have a friend who is a bit worried about this as it does not appear to be a rumour.Has any of you heard or experienced similar problems?Ithink I will hang on to my old trusty 4.2 standard diesel for a while yet.

G'Day Rambler,
I'm on my second 200 series best vehicle that I have ever owned.... touch wood not a moments problem with either of them, regular servicing & filter changes for me.
If you go to [url=www.lcool.org]www.lcool.org/
forum[url] you can see what people are saying there about various problems they are having.... with the number of Toyota's out out in the field there will always be a few not behaving themselves (unfortunately)

The answers so far are correct. With the number of toyotas on the road there will always be a few with problems.
And any contaminated fuel will cause problems for common rail diesels. Even cause a few problems for your older diesels but they would probably keep chugging along with a poor spray pattern on the injector.
The Toyota filter that comes with the car is very good being rated at 5 microns and incorporating a water trap with sensor at the bottom. Toyota have confidence in this filter so much that they don't even recommend changing it at every service - only change if needed. I personally do change it twice a year regardless and try to keep a spare just in case.
Some people have suggested adding a secondary filter but this is not recommended as the fuel pump requires at least 60 l/m flow rate. Any less and you run the risk of overheating and damaging the fuel pump. Hopefully the flow rate sensor would cut in before then and shut the motor down or go into limp mode with the error code for insufficient flow rate. Most of you CAV filters are only rated to max at 40l/m so these would be no good.
I had a quick google and came up with this one I have not seen before but looks good.

Best thing is to try to fuel up and good quality fuel stations and if in doubt purchase a Mr Funnel (
http://www.mrfunnel.com/Mr._Funnel/Home.html) and run the first few litres through this just to see if the fuel looks good. I have bought the Mr funnel but not had a need to use it yet.
Other than that I have heard people recommend a water sensor in the fuel lines.
My V8 landcruiser has done over 100,000 km now with no fuel problems. I have done regular out back WA trips but try to fuel up and high flow regular fuel stations. I personally had not met anyone who has had injector problems but only read of people being concerned about this. It would be a downer to be out remote and have your car go into limp mode.
Hope that helps the discussion a bit.
Cheers
Serendipity

Just one more thing that might be important in complimenting Serendipity's post......always remember that regardless how good the filter and how few microns it can filter to....it WILL NOT stop water and water is the single biggest problem contaminant for CRDI diesel engines.

The funnel Serendipity mentions(Mr Funnel) will seperate water from fuel.

Yeah you're right MickO - I have one of those as
well but it is a bu$$eer to use directly from bowser to tank. Works best when you go from bowser to jerry...
check for water and then chance you arm once you see the sump is clear of water and other gunk.

Yeah hear you. I've only used it from Jerries. It works a treat if you can get the swirl working. Hit that vortex spot and it'll suck down fuel as fast as you can pour it. It's just a matter of getting it going and hoping your arm can put up with the weight of the jerry while it empties lol.

Had an interesting conversation with a Toyota mechanic re the V8.
He told me that the only V8s that he knew of with injector problems had been fitted with an aftermarket chip.
He also spoke about problems with the starter motor. It is located on the top of the motor and water pools there after a water crossing. Very expensive to get repaired so if you do a water crossing just
check that the starter motor is not sitting in water.
