leaking injector

dwsc · Nov 20, 2009

I have got a injector leaking on a wd9 I am going to pull them later this winter, does anybody know where I can get the puller for the precups or a way to get them out

I would not mess with the pre-cups unless something is wrong with them. IH had a puller, but I have been told after the injectors are out to remove the head and drive them out thru the injector holes. Pay attention, they have an arrow marking "up" on them. Update us. I did this about 2 months ago.

I am not sure if there is anything wrong the the pre cups or not, the injector is leaking around the center. there are 2 bolts up and down and 2 studs side to side that hold the whole assemlby in place: so to get the injector out, I remove the 2 nuts on the studs and try to pry the thing out? would it be easier to do it if the engine was warm?

My injectors are held in with two 3/8" bolts with an o-ring dust shield. Three of them pulled out easily. One I had to use two end wrenches to pry on the ears. My injector man said they looked very good for the age. There is an aluminium gasket the injector seals against. He said they should be fine if undisturbed.

Now for the bad news. The parts for these old injectors are scarce, new or aftermarket. I found 1 supplier that had a kit, for $260. Even the injector man could not locate parts. He had some used parts and lapped them to repair my injector. Cost me about $125.

It was knocking like He!! with the leaking injector (combustion side). Now runs like a top. I am unclear about how yours is leaking... Around the nozzle body on top?

Here are some pics of my injectors:

Let us know how it goes!
