Sheared off with the first move of the spanner - how screwed am I ? Sheared on the inside washer so its all stuck in there...am so annoyed, any advice on how to proceed now?

[Marks DTM Calib]

Whish bit of breather?

[Marks DTM Calib]

I assume the bit that screws into the throttle body?

[johncol]

yes, thats the part Mark - is there any hope
Its a clean shear, nothing to attempt to grab and its in a god awful spot to do anything with...

[Grumpy]

It screws into the inlet manifold, below the throttle
body.

As it's sheared off, there will no longer be a tensile
loading on the remains stuck inside the manifold. So
you should be able to screw the remains out using
a screw extractor and a socket. With the Jet sheared
off this will provide the room to use the extractor
and socket. You only need to overcome the friction
on the threads, so if it's sheared because someone
over-tightened it (doing a bit of lesser-spotted leak
tweaking) it should remove fairly easily.

Be aware that as the Jet has sheared off you will
have lost the restriction. So if you attempt to run
like this you will have the symptoms of a large
unmetered airleak.

Get a new jet and washers from a breaker on here
and the best of luck.
Don't despair, this will be annoying but a fairly simple
fix with a bit of patience.

For anyone reading this thread that doesn't know
what a screw extractor is (we're all at different
knowledge levels) have a look at this link:

In this case, as the remains are hollow, there will be
no need to drill a pilot hole in the remains and risk
swarf going into the inlet manifold and then into
the engine.
So a bonus, really.

Thanks Grumpy 
I suspect I am the culprit for over squeezing it in the first place from a previous visit - so karma has well and truly struck. Its a tight enough spot so I hope I can get an extractor in as you say. There is a scrapped diesel miggy in a yard up the road from me, simpleton question - but does the diesel have a breather jet also?

[Grumpy]

No probs, johncol.

Never worked on the diesel, so don't know the
breather system set-up, I'm afraid.

Hopefully an oilburner owner or one of the breakers
on here will be able to answer your question.

If not, you'll have to do it the old fashioned way
and eyeball the scrapped diesel.

Cheers - I cant post in the parts wanted section so if someone had a breather jet with washers ideally, I would be happy to take them.

Where are you John? I got a local scrappy with a 2.0 in

Ah, Im over in Sunny Ireland - a bit far I bet from you

 I could take it off the one in the scrappy and post it over I guess?

[johncol]

Wow, that would be tremendous, but I dont want to put you out too much. I will see you right for your time etc and maybe send a Guinness or two back to you
