1KD-FTV injectors BDG or new DLC DENSO.

[Anth120playdo Banned Find all posts View Profile Close Anth120playdo]

OK I think I should share my experience. After my first set of Baileys showed signs of a leaking seal, I took it to BDG (after Toyota said there was nothing to worry about.) Matt happily replaced the seal and threw in a set of new injectors.

1500 km later number three injector failed at the Tassie Get together. Matt said he thought it was a "bot of dirt got into the fuel line during installation." Fortunately the injector stuck closed, so no damage done. Matt offered to send a set of injectors down, but I declined and got Launceston Toyota to fit a set of Denso's. Their service was great.

Conclusions:
. Like ####, I think there is an issue with the Brass seals.
. I think that one or more of the BDG service guys lacks care when fitting injectors
. BDG injectors are quieter than the Denso ones. I suspect this means they are a better product. They are fully DLC coated which probably makes a difference and certainly makes them quieter.
. I am still to hear from Matt about his findings and any compensation for the fitting of the replacements in Hobart.
. 40,000 km later no issues at all with the Denso injectors.

What would I do in the future?
If I lived near #### I would get him to fit BDG injectors with Toyota alloy seals
Otherwise as I don't live near ####, get a good Deisel mechanic and go with the Denso ones.

The real trick is to find a good diesel mechanic.

Just my opinion.

Leaking seals long ago. Probably Brass.
Just so lucky we have found what we did before it was too late for those engines.

Please remember BDG say, if you are not happy with their injectors they will give you DENSO.
They did it twice for us.

Thank you for your confidence in me, but to be Safe, we be installing DENSO DLC.

Cheers,

I would have thought they refunded your invoice, under the circumstances.

Is that True???? If not happy with Baileys they will give a set of Denso??

Yes. That's what I was told & they did it twice.

[TurboD4D Member Find all posts View Profile Close TurboD4D]

Yes.

Where can I find info on this??? They didn't let me know when I complained about noisy injectors. All they did was give me a long list of tests that a "Licenced Diesel Mechanic" had to conduct.

Keep it simple, Talk to BDG.

Another one, 30,000k. Brass washers.




This is what you don't want to see.

Just when you thought you saved an engine, you have to save them again.
Just in time.........

Today's find 2 with blow by.






Top right no.3 never sealed. Brass is very hard.
Number 1 just started leaking more recently.
Total just over 30,000k.

So we are recommending serious oil pickup checks.

Hey ####,

Tough materials problem sealing those injectors up tight!

Any idea what the hardness of the Baileys brass seats is compared to the Toyota copper ones?

Can be a wide variation in hardness depending on zinc content;

https://en.wikipedia.org/wiki/List_o...alloys#Brasses

An indentation C scale test is relatively cheap and simple to do on a flat component, might be worth a trip to a mechanical engineering shop for a simple hardness comparison. Would clarify things for Baileys as well!?

Conversion from Brinell hardness here;

Save a few more expensive engine problems as well!

The way to save engines is to tell people.
We think the brass is not suitable. It is a mistake. They came with BDG injectors.
My vice & hammer tests, show a massive difference.

The dawn vice struggled to mark the brass. You can see easily marked the copper. (coated washers)



Blow by may lead to engine failure.

Hey ####,

Wow! ...great and simple test!

Do you know what the material is underneath the copper coating on the Toyota sheets?

Needs to be a question on the census for 1KD owners to find out where to send copper sheets, just crazy that this keeps going on!

I forget the coating, but it's not a copper coating, it's a coating over the copper & coating over the brass.
Some zinc alloy something lol...... Not an engineer, ask MJ?

We know the brass is not suitable. It is a mistake. They came with BDG injectors.

So is it confirmed that BDG used brass on all their injectors? Mine were done by BDG at their premises when they first used the DLC (about the same time as Corigator). How likely is it that that I am going to have pull them again?

I leave for the Simpson in 4 weeks... guessing I'm dropping the oil this weekend.

Talking 1kd-ftv 778 Injectors.
It was confirmed in May. Yes many people got them done then.
So this means those are most at risk, by time & Klm's. 20-30,000k is getting close if oil pickup was not checked.
So yes check the oil pickup. I would estimate from seeing a clear oil pickup, with brass you have 5,000k window, or more, the leak vary a lot.
So if its clear now, you should be ok for your trip, I hope so.

To reduce risk substantially you need to know.
Check oil pickup immediately. Engine & turbo is exe.
Replace washers with Toyota genuine coated ones, when you can or right away if you have carbon on your pickup.

Hey ####, I'm not a metallurgist but I assume the coating on the copper seats is to minimise the potential for galvanic corrosion of the copper and is most likely nickel plating or similar.

So yes check the oil pickup. I would estimate from seeing a clear oil pickup you have 10,000k no problems.
So if its clear now, you should be ok for your trip.
Remember valve clearance checks by Toyota schedule every 40,000k. R&r injectors included.

I was hoping this information wouldn't have to come from me, but to reduce risk substantially you need to know.

Dropped the oil today - this is BDG DLC injectors, new in 2014, replaced in August 2015. 20,000km on this set. Feeling a little happier
