D24 woes...

monkeh · Jun 4th, 2016, 11:22

So I now am also after a D24 head. After removing the injectors for reconditioning, the chap who did the job commented on how sooted up they were internally.

I removed the flame arrestors to be greeted with 4 very burnt seats, indicating these injectors had weeped and corroded the aluminium away.
Thinking it would be fine, all the injectors went back in.
No, not fine. I have a lot of blowby from the injector threads. This head is stuffed.

Maybe, thanks, I will get a shop to inspect it... But I have a second hand head incoming thankfully.

Pics incoming soon.

If your shop cant come up with anything. Give Cotterell engineering a ring:

01246 250459

When i used to work there, i repaired many things like this. Mostly glow plug seats but all the same.
Very very good engineers.

I really have had a cant be arsed weekend with this. I haven't pulled the injector out but this is exactly what the problem is.

Does that look like something your shop could fix?

Its difficult to see on the picture, has the seat been completely burned away around the 7 o clock position ? If so the only way to get around it would be to put a steel insert in there. Machine most of the original area away . Just enough for the insert to sit against and press one in
.. anything can be fixed, if its a case of removing some of the original seat until a clear band is found again. It shouldn't be a huge pain to the wallet. If inserts need to be made it could be a different story.

The part that's burnt away is part of the sealing surface, between the flame trap/washer, the injector, and the head.
The washer forms a seal on the head, but as I found out, with that aluminium etched/corroded away, It would mean a repair to the head if its possible. But, there's not a lot left of that surface.

Will get some pics some point today. I've pretty much lost interest in this car after finding this.

Thanks again Willyvg

So, Here are the pics... Not good.

Also found out why I was getting boost loss which appeared to spike and drop off...

they all seem to be salvageable, none appear to have notches burned out of the, and so may be able to be tickled up to provide a shiny new seat. if you are any where near clay cross in Derbyshire, i would give cotterells a call, they are best qualified to provide accurate advice
