A way to remove injector sleves.
 

Set out to replace my injector sleves and o-rings. Of course my sleves didn´t pull out with the injectors. My inntakes are notched. Really didn´t want to drop the engine or start filing the notches. Made a tool that worked like a charm.

Cut a threaded rod lengthwise in half. It was just to big to fit into the sleve before cutting. Ground of the threads on both sides, so it just fit into the sleve. Cut down a hack saw blade to fit in between. When tapping the blade inn between the two halves the rod expands just enough for the threads to grip firmly. Perhaps I was lucky to get the size right the first time, but a few trials may be necessary to get it just right.

The rod and blade.

Inserted into the sleve. I grabbed it securely with pliers and used a wrench to leverage it up and out.

Success:D Looking at the state of them, I´m glad i made the effort.

Warning! It may be wise to weld a "head" to the rod-halves or use a long headed bolt instead. Mine could potentially have fallen inn to the intake. But I was being very careful and all 6 came out nicely :D Only had to loosen a few hoses to get to the hardest to reach intakes. I have no AC compressor in the car and no heating.

Nice work on the tool!

When I did mine, I questioned the fact, that brittle bits may fall into the combustion chamber.
So I decided to dismantle the air intake tubes and tap the sleeves out on my bench.
Great plus for doing it my way: you can clean EVERYTHING and adress cleaning much better.
Once on the desk, I even polished the inside of the tubes as far as I could vor better airflow.

I totally agree. Especially with all the gunk on the old sleves. Its not going to be pretty down the intakes:eek: I´m planning an engine-drop later, with propper cleaning of everything. This was just to be able to, quickly, address some air leaks, with limited work space and time :)

Nice work!

I’m thinking about replacing or refurbishing my injectors. Do you have a source for refurb?

Thanks :)

I´m in northern Norway, so no, not really ;)

In fact my injectors and the small o-ring looked like new (ish). I think the PO must have started the job, and bailed, when the sleaves wouldn´t come nicely. I got original P sleaves and o-rings.

Homemade tools.........
 

Good job. I also enjoy making homemade special tools too. This time you were lucky because the old injectors sleeves were loose and not stuck to the intake runners. Most of the time you have to drive them out using a rubber mallet to get them to slide out and have to get the intake runners off the engine. Nice tools.

Im surprised they came out with the nubs intact! I used a dremel to shave them down without the injector in just a bolt to plug the hole from debris.

I would like to make special tools for a living :)

Yeah, mine were pretty loose. I could move them about 1 mm up and down quite freely. They where pretty much just held in place by the notches on the intake runners.
