I've got a 2002 octavia 1.9tdi ALH engine and auto box

Beautiful car but one problem

Number 3 injector is "blowing"? I don't know if that's the right word or not, the side of the injector are caked in carbon - the copper seal at the bottom needs replacing

I spent 3 hours yesterday trying to get it out and it just will not budge - it's in there tight.

Today I paid a mechanic to come and take it out for me - he gave up after an hour and said it's really stuck in tight

Anyone know how to get it out? (ideally without it costing a fortune) It's already cost me £25 today for nothing!

the car runs ok just a little noisy. but I would like to get it sorted.

I'm in Manchester if that makes a difference to any of the answers.

If it's that hard to get out, then you need a slide hammer designed for the purpose. Any diesel specialist should have one.

They look something like this http://www.lasertools.co.uk/item.aspx?cat=371&item=3470

Ouch - that's expensive - when it's only needed to change a washer that cost 54p

had a look and most seem to come with M8, M12, M14 Adaptors

Any idea which one I need for the injectors on the 1.9tdi ALH?

Looking at them they seem to be basically a long bar with a heavy thing on it that slides up and down, and the end is threaded to fit on the injector?

What's the size of the screw bit on the top of the injector?

IIRC, the union nuts are M14x1.5

If you are going to make a tool, then try and find a fuel pipe with the union nut attached.

Use PlusGas very sparingly to aid removal.

yes dont forget that any relaesing fluids you spray around the injector could find their way into the combustion chamber as the injector comes out so it would be worth spinning the engine over on the starter for a few seconds once you have it out.

the injector union is M14 and it is pretty easy to adapt any slidehammer to work if you have an old nut to use

When ive had a issue with a stuck fuel injector ive had a result with soaking the injector overnight with coke a cola.Its not a joke,it does work.

Another thing to note; clean up the area around the injector as best you can BEFORE removing it, otherwise that crud will drop into the cylinder when you remove the injector. Trust me, been there, done that . . . .

And when the injector is out gently clean the body to make it easier to refit, but DO NOT touch the nozzle with anything, unlike a bloke I know who did exactly that and ended up having to replace the injector which cost nearly £700. It was on a common rail diesel though.....
