Technical Injector seals

[Mr Posh]

I’ve had a smell of exhaust fumes in cabin
Vauxhall combo 1.3 it’s down to leaking injector number 4 I’ve taken injector out full of crap and black carbon cleaned it up the seat looks like someone has had a go at it the seat has a Nick which looks like carbon has got into it I’ve recut the seats but it’s still there I don’t want to go mad with the cutting I’m thinking it may be new head I’ll post pics tomorrow

I have recut the seats on a few of those in the past and as long as new copper washers and torqued down correctly have had no issues.
Maybe see what the photo shows.

 

[Mr Posh]

Thanks for that I’ll get pics up tomorrow

I can see the nick although as you say a little out of focus.
I would try a bit more with the injector seat reamer, the one I have did cut a better seat, so if it is sharp and only turned in correct direction it should cut effectively, I also used a little WD40 as a cutting agent.
By the way make sure the new copper seals are a good quality as cheap ones are hard copper and don't seal as well as softer ones.

Nice one I’ll try that I’ll get some genuine VX ones

Or from a good diesel company. But get the seats as good as possible first.

You may need to carefully recheck the hold down clamps for tightness on the injectors after a few miles once settled diown, as I have found it worth doing.

No problem thanks for you help
