V8 Toyota troopy problem

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)

Contaminated diesel is a problem for ANY common rail diesel (CRD) engine, not just the 200. As the 200 has 8 injectors, the price to replace them all is higher than the typical 4 cylinder diesel.

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.

hi
you may gain some imfo from thread 89364
cheers

Our 76 has over 130 on the clock. Touch wood we have been lucky on the fuel front. Still we always carry a spare filter. I would be more worried about the alternator. Its low just like our old 80 so we keep an eye on it when around mud. Apparently there is a trick with the alternator we picked up from a friend. I'm sorry i wasn't around when the fellas were under the bonnet having a look. Some one else on here might know what I'm talking about.

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.

a minesite vehicle with 50,000k is extremely 2nd hand and would have ahd numerous issues at 100,k it would very much be at the end of its life

these things need to be put into perspective
