diesel rattle in D4D Prado

[mjrandom Out of control poster! Find all posts View Profile Close mjrandom]

Cannot tell you definately what the factory interval is but it is mentioned. I have 60k for the 'tween tanks filter and 40k for the under bonnet filter in my head for some reason. However I used to change one or the other every 10k on the 120 and will probably do the same on the 150. That way no filter was in more than 20k and I used to forensically examine them after replacement. If you look at the preventative maintenance thread on the D4D started by John the Roo I think he mentions that you can change both at 60k if you have the 3rd party filter before the final under bonnet filter.

It is the between the tank filter that is the one changed every 20k. The under bonnet one is only changed when the light comes on, which is not a great system if it comes on in the middle of nowhere. MJ'S,s idea on swapping alternate filters every 20k seems like a pretty sensible idea.

I am with you Rick.
But if the flanges after inspection are in good order, why not use them again. I disagree with the 5 times thing. Twice is all I am saying here. In Australia, it costs about $530.00 for a set of pipes. So if you can use them again, you do.
Anyway, with most good diagnostic tools, you can do a pressure test after you have done the job, to check for leaks in the system. It's part of the procedure.
I mean, if you get a leak in number four, what a bastard of a job. You always know, pretty well, when you are undoing those union nuts, if they have been over torqued or not. So this is when I usually have a talk to my customer about the extra for new pipes.
The Roo.

Rick, Roo - Thanks for the replies. The reason I asked the question about new pipes was because when I had my injectors replaced, they didn't replace the pipes. I could smell diesel for a couple of week after, thinking it was just spilt diesel from the job and that it would dry up and disappear. This didn't happen so I had a look and there was a slight leak around number four. Took it back, they "re-seated" the pipes and it fixed the leak.

Thanks Mj and Aj for your help. What is the micron measurement of this "between tank " filter? Any clues guys? Cheers Dave

NFI. I don't do the work myself, Prado is leased so goes to the dealer. I just ask for the extra bits on the services.

Gday davelozt

Guys, whats the go with the filter between the two fuel tanks. mine has done 110,000 kms and hasnt been changed. toyotas service schedule doesnt include this filter. Should i change it and any idea how much? Dave

Click on the link below for the pics of the duel fuel tank filter for the diesel (Mainly for others to see who may read this thread in the future).

Underbody fuel filter

And here is another link for the alternative choice/Options to replace that filter!

Underbody fuel filter

Not sure on the Micron, I have one sitting here and no mention of Micron size on the box or the filter. Part number is 23300-30310, a quick google of that number and the word "micron" might help you find out. I had a quick look but nothing definitive came up straight away.

Cheers Andrew

That's not good news I'm afraid. Mine developed a ticking/rattle with no loss of power etc.
pulled motor apart to find no1 cylinder scored from the piston. This was due to a blocked oil pick up screen. All relates back to an injector seat failing and allowing blowby to occur.
I cannot believe that TOYOTA do not accept this is a common fault and a manufacturing defect.
Bottom line is sounds like a new short motor.
Hope I am wrong but give me a PM if you need any info as I have just been through this exercise.

Guess, what? Just got the news today - the exact same thing.

Oil screen full of carbon, engine starved for oil. #1 Cylinder scored.

Will be talking to insurance company when I get home. Not impressed, to say the very least.

Thanks Skywalkerrun and AJ120. Im going to stick with the Toyota filter , call me a fool but I have just spent a shit load of money on new injectors,seats pipes (twice) and seals etc, so Im not going to take the risk on after market filters. P.S. Just had the Baileys DLC injectors fitted and touch wood, the Prados running like a rocket! Smooth idle and no RATTLE or SMOKE! Thanks also to the Roo for all your advice as well. Cheers Dave

Toyota and other manufacturers won't let each competitors know the size of micron but all common rail fuel systems need to run a 2micron filter for primary filter and around 7 for pre filter ie the tank filter. Fitting a donaldson common rail fuel water trap housing is a cheap and worth while mod. They are 5 micron and flow well.

Why is it that in most of the old threads re/ fuel filters on this forum, the main filter/water seperator under the bonnet is quoted as being 2 microns when toyotas web shows it being 10 microns? Did they change it in the last couple of years?

Worth noting that in Donaldson's explanation of beta standards they mention the tendency of some manufacturers to give multiple micron ratings. I have just read a post attributing and promoted this as a very special feature of a particular brand of filter. The posters interpretation is wrong. So there can be no mistake I am not criticizing this poster but I mention it as it is just an example of not quoting beta standard when microns are mentioned. Also this is not a criticism of the particular manufacturer but an example of how micron ratings on their own are not only meaningless but open to misinterpretation. The truth is all filters can quote like this and all are correct so nothing special.
Fellas please find out the beta standard stated by the filter manufacturer and state it in your post if you mention microns. Without the applicable beta standard you are simply talking gobblygook. To those who do not read the link in my previous post please do so before replying.

Very interesting reading. (Donaldson tech talk). I see where your coming from Kitbags. Makes the choice so much harder, and yes without the beta standard stated, mirons on there own are useless. You need to know the beta rating to evalue the efficiency of the filter material/flow rates etc. I will be doing more home work. Cheers Dave:wink:

This is probably the extreme - and as far as I can tell, Toyota doesn't even look at the P/U screen on a service....

But that is the condition of my screen when engine was making "death rattle"....
