Default !! Stuck injector!! Any ideas

I have a stuck injector on #5, I’ve used a ton of penetrating oil and a 5lb slide hammer and still not budging. I can get a very small amount of wiggle out of it with a prybar but it still wouldn’t turn.

Any ideas how to get this PITA out???

I remember seeing a tool that 'lifts' or prys the injector out of the bore. May have been a Harbor Freight tool. Google is your friend. Maybe Youtube, also.

Get a can of TC-11 and hope and pray. If not, slide hammer may be your best bet.

Slide hammer always works for me on stuck injectors. I made an adapter to allow me to attach my slide hammer to the fuel line fitting and make it so the slide is parallel (or close to it) to the injector body. I have yet to have one that wouldn't come out, but some of them are very stubborn and take a lot of hammering to get them out.

If it's stuck due to carbon build up from a leaking tip washer you can use paint stripper or gasket remover to soften it up. Works well with the sprinter injectors and their "black death".
