diesel rattle in D4D Prado

[MarkCurl Lurker Find all posts View Profile Close MarkCurl]

Hi Guys, newbie to the forum!
I have an 06 D4D Prado that I've owned since new. Has only done approx. 123,000Km. Last Saturday I decided to investigate the excessive smoke on start up ( after sitting) that the wifey was complaining about. When I saw the amount of Black/Grey smoke and the erratic idle that lasted a minute or so - I deduced I had a leak-down problem in an injector or 2 ! Decided to attack it there and then with the intent of changing the 4 injectors out. Discovered 3 out of 4 had blow by on the injector seal and the combustion gases had actually forced the oil O ring up the injector and torn/smeared them. Lot of granulated carbon around the injectors which also co-incidentally have an oil gallery linking then all just above the O ring. So immediately dropped the oil and the sump to check the pick-up screen - thankfully as clean as the day it went in there. Next step was to find a worthwhile supplier of replacement injectors, several stages of heart palpitations ensued after discovering the cost - anywhere between $460 and $600 and apparently no exchange options available. After googling a few threads I came across Bailey's Diesel Service. What a pleasant surprise - exchange injectors offered, blueprinted and a 2 year warranty. Ordered them Monday arrived Tuesday and fitted them Wednesday night. Nett cost of approx. $1100 after returns. The Prado has it's MOJO back! runs smoother, idles quieter and definitely pulls better when you give it a kick. Tanks to the Prado Point forum for all the comments etc it has been helpful. p.s. I did try Toyota on regards the seal failures but no luck there :-(

Markcurl - Sounds like that was a close call. Could have turned out much worse.

HI Guys

thought i would post my experience as well....My 2010 Prado had the old rattle for about 20k before I got onto it (once I saw this page). I called Baileys Diesel....they told me the cost and recommended Central 4WD centre to do the install in Melbourne. I made the call that day to proceed.....2 days later the injectors were in and my car has never run better. Highley recommend Baileys and Central 4WD centre.....they tell me they are doing 5 of these a week using Baileys injectors....Great service. Cheers

Mechanic in Rockingham/Mandurah area?

Can anyone reccomend a mechanic in the Rockingham/Mandurah area of WA that has some experience with checking or fitting injectors? Or would you recommend taking it to a Toyota dealer?

I have an early D4D Prado (2006 build, 2007 del) with 150K's that seems to run fine, apart from blowing white smoke on start up for a few seconds max. I haven't had the vehicle long enough to know if it's noisy on a cold morning, but there is no noise on a normal 12 deg morning. It has a service history every 10K's but not by a Toyota dealer.

Just another thought on the dredded diesel rattle at start up... I recently discovered that I have a second feul filter under the car in addition to the main under bonnet one, it is above the rear prop shaft and beside the front fuel tank, and I had never changed it (100K+ks). Also laterly I have been getting more and more rattle noise on cold mornings until the engine warmed up.
Having now replaced the under-floor fuel filter, the rattle has gone away... magic!
It had a black sludge in it ( when I blew backwards to drain out the fuel...) this I believe is the result of "Diesel Bug" in the fuel. I have given it a dose of fuel additive to hopefully kill any remaining bugs (actually an algie), and will watch the new filter incase it catches more bugs.
For your consideration.

Good to see you're up with your maintenance. That filter is supposed to be changed every 20,000km. It helps stop the crud from reaching the main filter, your pump and your injectors.

A little bit out of your area but I have recently had the injectors replaced by Fremantle Fuel Injection.

Not cheap, but happy with the job, although it has only been a couple of weeks.

The bloke to speak with is Michael Hulme, the Service Manager, Ph: 9335 4803.

I was lucky enough to have the use of one of their vehicles while mine was getting fixed.

No affiliation, just a satisfied customer.

Rowdy

The white smoke on start is defiantly a sign of the injector seal failing, I would be getting the values checked and at a minimum the seals done.

Good work on the fix.

Which fuel do you use? Do you know if its bio? A.k.a choock fat?

Thanks for the advice. I will give Fremantle Fuel Injection a call.

I've also noticed an injector rattle when cold and under load.

Can anyone give me a simple explanation of an injector value and an injector flow rate or are they the same thing? Can one be ok, but need replacing because the other is out of range?

My new engine is coming up for 40K but the head has done 110K. I assume that the valve clearance check should be performed at next service?

Hi all. I am a new member and my brain hurts after 143 pages of confusion! My recent purchase receipt states that my bus is a 2009 CP build 07/09 KDJ 120R GXL.I have two simple questions. What series is my vehicle? Does my make and model of vehicle have a history of "death rattles and/ or injector failure". When I pick up the vehicle next month, I plan on fitting all new filters and aCAT water / fuel separator. I have also asked the mechanic to inspect the fuel pump screen. Do these actions sound the right thing to do? Sorry. That was three questions. My brain is hurting even more.

thanks in advance for any help. Ouch! Heals.
