    Default Having some real bad luck, help.

    Ok so I was replacing the Orings on my injectors since one of them was leaking right
    Got them all on the car and I took off the distributor cap to move the spark plug wires out of the way, I seen that it needed to be replaced since the center contact inside the cap was damaged.
    I put on a good one I had laying around, got everything buttoned up and started the car
    It obviously wasn't running right and was misfiring
    I finally came up with the conclusion that the rotor in the dist must have been shorter than what was needed for the new cap that I put on. I put on a different rotor and it finally started up fine and sounded like all cylinders were firing correctly but now my car has a very loud knock from what I think is the head/valvetrain
    Could some really have been damaged from the misfiring that happened?
    I just had to step away so I could calm down, anybody ever had anything like this happen?
    Really hoping it isn't something serious but I'm kind of doubting that

    well crap!

    that chunk of crap "the button" went somewhere.

    get your rotor button off
    get the round fin thingy off that passes through the pick up module down in the dizzy,, mark it so you you dont put it on wrong cause i think you can.
    see if you got garbage down on the magetic pick up.

    other than thay.. id say its spark related... its gotta be,, and im just reaching here.

    all you did was change out the cap and button.

    Is it possible you have two wires in the wrong firing order?

    I will see if there is anything in dizzy, as of right now it sounds like all cylinders are firing and it runs fine except for that knock
    I'm still not driving it around because the knock is too loud for me to think my engine is just fine.

    Thats what i thought was wrong as well at first but i checked and the order was correct.
    After I swapped the rotor to match the new used cap it ran just fine minus the knock...

    well, then id say your spark plug wires need looked at,,, you may have sparated the metal clip from the conductor in the plug wire,, making spark delivery difficult or not at all.

    lack of spark on a cylinder will generate a knocking noise

    When it's running pull each plug wire off one at a time. The knock may go away or diminish a bit, you may find what cylinder is the issue. Possible could anything fell in the injector hole and is hitting on top of the piston against the head?

    If you like i can take a current graph from my scope open circuiting Secondary side wiring!!

    Wow I am stumped
    I found out that cylinder #4 is not firing
    I tested the spark plugs, wires, injectors, everything and it all checks out good
    All injectors are getting voltage and working properly
    Compression #'s : 137 , 140, 110 , 133 firing order: 1,3,4,2
    But these pressure numbers were very similar to my previous compression test so I don't think this has anything to do with the prob

    The only thing that comes to mind is a mechanical problem

    I just don't know how this problem came up from me not even driving the car, my car has been in the driveway the whole time

    Hows the timing belt? Might it have slipped a tooth? Also check the distributor for play or shaft waller. And also they have a tendency to chew drive gears. Might be somthing totally stupid just ideas
