Cutting fuel to one injector

I don't know why I didn't think of this before... One of my cylinders isn't firing, so a little fuel is probably leaking past the piston rings and getting into the oil, and obviously 1/4 of the gas isn't being used at all. So, my question is: How do you cut the flow of fuel to just one injector?

    You don't. Replace the injector!

    if you have to why not just unplug it? :roll:

    No compression.

    Hm... I just might. I guess I just didn't know exactly what would happen if I simply unplugged it.

    Oh, no compression... fix the head! I know it's easier/cheaper said than done. Unplugging the injector won't hurt a thing. You shouldn't have to worry about oil dilution though, the raw fuel will just puke out the exhaust- path of least resistance and all that... To force fuel past the rings into the crankcase, you would need COMPRESSION with no ignition (and some seriously worn rings)

    Why no compression?

    Worn rings. Haha, i don't think they're that bad, but yeah. I'm planning a DOHC ZC swap whenever this motor decides to crap out. Been puttin' around for a few months now.

    Worn rings? Not likely if just one hole is dead.

    Explain...

    Well, piston rings tend to wear evenly/ the same in all cylinders. When doing a compression check, if you see one hole low you immediately think "head". I won't say that it's not possible to have only one piston with worn rings, but I ain't seen it...and I've seen hundreds.

    If your plug is oily and the cylinder's full of oil, you MAY have a hole in that piston-caused by a dropped/chipped valve maybe. Get up with evol911, didn't he offer to help? What's the chances of somebody else on Whidbey on here, too, and willing to hook you up?

    The plug is oily. Strange. Thanks for the information. I'm not too worried though as a swap is in my near future.
