My nbr 3 injector is stuck, I did 45-50 pulls as hard as I could and it has not budged. Sprayed blaster into the hole and let sit two hours and still will not budge. Car is beginning to drive me crazy, nbr 1 injector came out in 35-40 pulls and was surprisingly clean and was surprised it was not the original injector.

Any help would be greatly appreciated before some lunatic sets fire to it.

 

Do you have the slide hammer injector removal tool?

 

Have two, first one (made by UTool) broke after 5-6 times, I now have the DP Tool and it seems to be a much better product.

 

Haven't dealt with this myself yet, hang in there. Note the guy in the video used a ratchet strap to provide constant pull as he hammered. Seemed to work well, but even then it was quite a task.

 

Can't find in the manual, but is bank 1 the left side or right side of the car looking from the front?

Error code says bank 1, but service manual says bank A and B

 

Bank 1 (= Bank A) is the right side bank ie the left side when looking at the engine from the front of the car.

 

cherry picker or modify and extend the stock tool to use a heavy brake rotor

 

If you've already sprayed a penetrating fluid around the injector, let it be overnight before making more attempts to remove the injector. Bear in mind the injector body can break as it's made of plastic.

There was one injector on an AJ126 that needed well over one hundred hits with the slide hammer tool for it to release from the cylinder head.

Once the injectors are removed, use brass wire brushes to clean the bores for the injector tip and body.

Use the resizing tool to resize the Teflon injector tip seals prior to installing the new injectors into the head so they don't deform and leak during the compression stroke.

 

After 2 days of spraying pb blaster and slide hammer I used a crane. It worked

 

So I'm expecting to have to deal with this sooner or later. 2015 R with 30k miles, i garage it and keep it out of the rain but still... so once this happens and we get the injectors out, anything practical we can do (aside from using a wire brush to remove existing corrosion) to help injectors resist seizing to the block again?

 

@bfrank1972 I am putting anti seize on the back side of the injector, i.e. behind the seal. Also, I have no cherry picker and absolutely nothing to hook a strap too. Going to try and get the last two out tomorrow after 2 days of soaking with blaster, will let you know tomorrow whether the injectors are out or it caught on fire and burned to the ground. BTW, that was PURE sarcasm, for those that do not know,

 

@NBCat I have brass brushes and carbon spray and yes, thank you I did resize the seals!!
For anyone looking to do this, if you are slightly older and maybe out of shape with big hands. You will slice and dice your hands and have frequent breaks for rest and do put a towel around the slide handle so it will be easier on your hands.

 

And as a side note, do not get the Utool and do get the DP tool, DP Tool is great. UTool broke after 5-6 hits and the guy I bought it off of on ebay was great, he sent me another one, even though I bought it 2 months ago. Have to say ebay itself does not give a flying F@@# about its customers, they are all about their sellers, thank goodness I found a very Good seller (autotool-store20).

 

This morning I said a prayer for you, and then another for your car. Patience usually pays off (eventually,). Wax on, wax off randy-san. Keep us posted on how it goes!

 

My mechanic took 3 days to get last one out! Soaking, tool etc.!

 

Jumped from nbr 3 to nbr 5, scared the you know what out of me when it came out on the second pull. I fell back and thought oh no I broke another tool LOL. Nbr 3 has been soaking since Saturday and still will not budge, I must have done close to 200 pulls and it has not moved. Going to try again in the morning.

On a side note, drained my oil and have a 10qt drain pan, it overflowed. It was like water with all the fuel in it, glad I did not try and drive the car.

 

Yikes!

Keep us posted.

 

Would freezing spray help at all? Seems crazy that these things are so hard to remove. Just trying to think what additional things might be done to help. The other crazy idea is possibly drilling them out? How’s access for that? Is this idea nuts, too? I’d use an undersized drill to ensure you don’t mess with the sealing surface, then maybe a reaming tool to remove additional plastic?

 

My understanding is that the difficulty with injector removal stems from the buildup of carbon on the tip, inside the combustion chamber. The carbon is relatively soft (but stubborn) so pulling it is the best action.

You don't want to drill, as anything that falls in will damage the rings & seals.

 

You likely bent the injector while atempting to remove it.
I recommend getting a new injector in there, these injectors get damaged easily while removing,
the symptoms could take weeks or months to show up.

As far as removal a vibrating tool may help
