diesel rattle in D4D Prado

There's no consistency across the dealers when it comes to policy so I doubt head office knows anything about anything.

Did you get a response from Baileys on the use of fuel additives?

I certainly asked the question when ordering the injectors. The response was, "Really don't think you will need an additive, but it's up to you."
There was no definitive response to the negative. My D4D is running better than ever... quiet from even the coldest of starts and smooth as silk.

I should add... I have been using BP Diesel (not Ultimate) exclusively, FWIW. On a recent country trip I covered a little over 1500km and managed economy of 10.6L/100km, which is 1-2L better than prior to the change of injectors.

Who should I approach to have my inlet manifold and EGR cleaned out? And what cost range should I be expecting?

I have a can of LIQUI MOLY PROLINE Diesel Intake System Cleaner but have been busy and it is still unused...

I guess a catch-can and EGR Blanking Plate (10mm hole) is next?

I can be there WEDNESDAY, lol...........

$300-$1000? But don't just get the manifold pulled off. It very rarely needs that.

7mm hole.

LOL... Halfway between Cessnock and Maitland, NSW... 35mins West of Newcastle...

Could I use the LIQUI MOLY Diesel Intake System Cleaner sprayed into the air intake AFTER the I/C...??? I think that is how they recommend using it???

Saw your 7mm EGR Blanking Plate suggestion in another thread I am still reading... TY for the link... already purchased!

I would not recommend any spray cleaners till you know it's pretty clean, perhaps use to keep it clean, but not to clean it.
There's a lot of crud in there you'd prefer doesn't go through your engine, turbo & cat.

Is it a very technical job, or is it something that a decent DIYer could handle?
And how do you clean the crud out of the manifold without removing it completely?

To be honest, I like to teach the owners how to d.i.y as much as possible, so I can concentrate on the hard / technical stuff.
You could be ok, others who have done it spent most of a day & p.i.t.a.
I don't recommend d.i.y unless your are very patient & good on tools. It's very fiddly.
The kind f job you just pay the $500 & let the expert do it, it's only going to get done once or perhaps every 5 years with injectors.
The manifold is not usually full of crud, it's more the elbow.

Patience? Perhaps over a weekend and a few beers...
Sorry, missed your PM ############# till it was too late to respond.

Yes exactly

Found something interesting today, the diesel rattle on mine is coming back but slightly different. Ran techstream and injector feedback readings all the same as when i put the BDG injectors in 40K ago. Only worry is the fuel pressure against target, always a little low. So changed both filters, i run a 2 micron parker filter after the OEM unit and next morning noise reduced. Next morning tried with the 2 micron removed and even less rattle.
Will run techstream over the weekend to monitor if the target and actual pressure are closer. Regardless of filters the rattle stops after the engine reaches 50 deg C.

Theory: when pump is a bit old any extra restriction such as dirty filters or too much filtration causes pressure not to target and the ecu opens the injectors to compensate.

Cheers for sharing, as you do.

Fuel pressure is usually just under target. At 35000 normal jumps from 32000 to about 35000.
They can jump a bit, you need to look at reaction time, & as long as its not jumping round too much.
Sometimes you cannot diagnose, Scv is another wear n tear item often causing problems around 200,000k.
So if you have not yet changed it...........

SCV changed earlier this year. Did make a difference to reaction times but the old unit was not too bad.

Hmmmm... interestingly enough, I am about to prepare myself for performing the 200k service in about 6 weeks time. Will have someone else do the valve clearances though. Might look at doing the SCV then as well. Expensive?
