Default Removing a stuck injector

I was pulling the injectors from an alh head a few days ago and one of the was just cemented in there. It didn't matter what I did that thing wouldn't even rotate 1/16 of an inch. I soaked it in blaster for a few hrs, nothing, wouldn't budge at all.

The fix was I took a mini torch, put it inbetween the the block and the injector for about a minute, within 2 minutes I had the injector out without even using a slide hammer.

Just another idea for people who have one that is hopelessly stuck.

maybe I'm wrong, but I wouldn't think that would work until you have the darn thing loose, I've never had to use a slide hammer on an injector so I wouldn't know if that would have been the correct application. I can definetly see it being useful when the injector is spinning a bit.

I had a couple that wouldn't turn at all... even after days of PB-Blaster showers... I borrowed a MetalNerd injector slide hammer from Wingnut (who also has built his own) and they came out very easily...

Slide hammer is a must!

These will work on on all injectors from 1996-2003, won't they? I need to remove mine on my '96 passat with the 1Z.

I wrapped the threads in a bunch of shop towels and simply used plyers over the protected threads to pull and rotate them out. Not a scratch on them - didn't need to buy or make a slide hammer!

Yes. 1Z, AHU & ALH. Probably lots of other Euro models as well (ASV???)

If you're only going to remove TDI injectors once in your life, then yes you probably don't need this tool. But when you can substitute 10-20-30 minutes of wiggling, prying, cursing and sweating for two or three satisfying smacks, it really helps.

Thus concludes my salesmanship of the tool. I'm not out to make a ton of money on these. I just think they're cool.

^^^, some are stuck more than others.

Check out the puller in runonbeer's sig. If I didn't already have the metalnerd I'd buy that because it's a great reuse of parts and the price is good too.

Edit: runonbeer slipped another post in there, my arrows reference tydaddy's post.

There has been more than one occasion that I was glad to have an injector puller on-hand. Most of the time they come out without any problems then you get the one that just is bound into place. Then there is no tool as good as a slide hammer.

Sorry to resurrect this thread.

So I have an injector that is way stuck

It doesn't turn.
I have used the metalnerd tool and this injector just laughs at it.
I added about 10 lbs of weight, still laughing..

I've used heat in combination, no luck.

Short of pulling the head and beating it out from the reverse.. does anybody have any other ideas?

I'm stumped.

Just keep banging slide hammer till it comes out. Some of that are really pain in neck.

My #2 injector was like that. Did you try alternating hammering down and up with the slide hammer? Keep doing that in conjunction with penetrating oil. May take a while but mine eventually showed a little movement and finally came out.

The simple solution is shake and bake. The injector will come out. You may use a puller otherwise.
