Injector Rattling in 2007 120 D4D

[SlauteR Lurker Find all posts View Profile Close SlauteR]

OK so I kniow this topic has been talked about many times but the thread for it is 100 pages and I dont have time to go through it all. I have a 2007 prado D4d engine and when it is cold it has a rattle at about 1500-2000 rpm. my question is to fix this can you just do a straight swap out of the enjectors. will this fix the problem or is there something more? please if someone could tell me what needs to be done so I dont have to sit for 5 days and read 100 pages of threads it would be greatly appreciated. and by any chance was this issue ever put to a recall by toyota or not?

Thank you in advance for any help.

Yes changing out the injectors should fix the issue. If I were you I would go to the link at the top of this page for Baileys Diesel group and get in touch with them for a set of injectors and some advice on where is the best place for you to get them fitted. Whilst getting the injectors changed I would also get the oil pickup screen checked for cleanliness as leaking injector seals may have caused some issue here as well.

You don't say how many kilometres you have done but given its a 2007 your talking about a 7 year old vehicle that likely done well over 100k, I would have thought injectors needing replacement at that age would fall well the within the bounds of normal wear and tear.

I have a 2007 D4D and had the injectors replaced under extended warranty at about 77000kms .
To ensure it was the injectors had to leave vehicle with Toyota overnight so they could do a cold start in morning.

Original injectors were a problem for lots of us as the 100 pages will show.

Suggestion about Baileys seems to be the way to go as good reports on forum

I had same problem. Same make model and year. Replaced injectors with the ones from Baileys about 2-3 weeks ago. Was smooth and quite. Rattle has started to come back not happy Jan!

Likely injectors will rectify your BIG issue.
You should also have your egr system extensively cleaned.
If it has the old copper seats, & blow by, it may need to sump removed & clean oil pick up.
I'd say let it warm before you drive it, or don't drive it, get it check out ASAP.

Check your values? Might have a faulty one? Or a faulty installer? I mean dirty installer?
I have seen some dodgy install jobs, you are dealing with holes smaller than a human hairs, & fine clearances on other moving parts, plenty of dirt around bigger than that in some filthy engine bays.

Cleanliness is next to godliness with this job.

you are dealing with less than 1 micron on your nozzles

Who says that?... Was that your assumption or was you told that?.....

You are aware there is 1,000 microns to 1mm.

How many microns is the Euro4 fuel filter again?...

Isnt the injector tip size "bigger" than the fuel filter size of 10 micron or did i miss something?

Also!

If injector was playing up because of faulty installer it would not play up 3 x weeks later would it??... but rather on the day of installation me thinks!

In all fairness wouldn't you expect the engine to be smoother and quieter if replacing old worn injectors with new?.. That's what i would expect anyway!

Sorry it was typo, but I have edited to save arguments. I know the spec & nobody else really needs to but yes it's well over 1.

Yes.

Fuel filter, depends who you believe?, depends what temp the filter is?, did u take into account expansion?
I hear 5 & 8 not 10, but who going to argue?

Yes much bigger.

Also!

not necessarily.

Definately! He said it was. Obviously there is a problem somewhere.

Every time I install a set of BAILEYS BLUEPRINTED INJECTORS for a customer, the vehicle is transformed!!! Silent in comparison! In fact quieter than 150 series with under 10,000k on it.

well actually the injector tip is "much" bigger than 10 microns

That's what I wrote yes sir, correct! Over 10 times bigger.

sorry I should have mentioned that it has done 180ks but the injectors were changed at 150. As I didn't own it then I don't know what they replaced them with. I only know they were done and it was recorded in the service log book. If it was done by Toyota surely they were replaced with the right injectors. (or were they) hmmm

Toyo have a habit of replacing only the ones that are out of their spec.
So you might have been told it had new injectors?
It might be 2 injectors, it might need 2 more?
I suggest replacing them as a set of 4.
Have your feedback values checked & you will know heaps more.

Suggest having the Suction Control Valve checked, once new injectors go in it is (apparently) the next likely cause for concern...

You can check its operation via techstream (fuel rail pressure) or manually by measuring the resistance across the SCV terminals - this is fun to say the least and small hands and patience are handy, unless you're prepared to take the SCV off the pump.

ps you're looking for 1.9 - 2.3 ohms (at 20c)

Have the same problem with the 07' prado I have just bought(3 weeks ago). I was also told the injectors had been changed previously at 90000k's(now has 140000k's) and so I thought it wouldn't have THE problem as i couldn't hear anything obvious when test driving it, only to get it home, start it in the morning and have it rattle its you know what off! I have it booked in tomorrow for all 4 injector replacement and thanks to this forum i will have some other checks i will look to get done(hopefully at not to much more cost) e.g oil pump screen cleanliness, erg cleanliness. Fingers crossed all goes well.

Mine is heading to Baileys on Monday and they did mention they'd be looking at this as well.

X 2 right!

I suggest when changing injectors, just change out Scv, same with the new fuel lines.
Small amount extra to spend & you will save yourself a few possible problems a tired Scv can cause.
Fairly common issue.
