i have a 1998 escort, and it does not run that bad.


UNTIL

my girlfriend took off last night and had to run some errands,

she was going over a over-pass, and then the car started dying, she said that the car lost all power, and just came to a stop. she was able to get help pushing to a gas station, then she put ten bucks in the car, poop it does not want to start.

i get there to take a look, and i look at the spark plug wires,

#1 stays on and is tight,
i move to #2, and the thing is tight and secure

then on to #3, when i try to pull it from the boot, the wire snapped and the boot stayed in the #3, and the wire detached.

well i tried to ghetto rig the wire, and get it home...

but when i started it! it sounded awful!!! knock knock knock clank clank clank... e

I am pretty sure the valve seat failed, and the valve dropped into the cylinder.?? so i was pertty bummed, cause i do not have mch money.

but that spark plug wire (the one that jst pulled apart) just would not leave my mind, and after doing some reasearch online for hours (its 4 am now) about spark plug wires, valve faliure, knocking pinging, knock sensors... i still am not sure.

from what i understand... broken insulation on a wire can cause spark knock?

can what i hear from my engine be spark knock? or is it the common valve faliure on #4?

tomorrow is sunday, i have no work (and no ride to work)..

what should i do?

any help is greatly appricated.

thanks!

take off spark plug #4 an see if the electrode is all smashed up an do the same on the others to see their condition.

How old are the spark wires?

I find this post interesting. Is the #4 cylinder on the far left? I had a spark plug issue a while back on that one. My plug wires are also hard to get off the plugs, much like you are stating. I've gone through 2 sets thanks to the separation of the tip from the wire. But one time I put Bosch Platinums in and within 10k miles, there was a god awful sputtering going on. Upon pulling the plugs, the one on the far left had the electrode tip inside completely broken off and was rattling around inside the plug itself luckily. It hadn't fallen out into the cylinder. What could cause this? Extreme heat in the cylinder? There's nothing in there that would break it off by hitting it. Never figured out what caused it but it hasn't happened again. But the plug wires are a pain in the arse to get off on mine too.

Number 4 cylinder is on the driver's side of the car. I just remember that on most engines, cylinder #1 is closest to the drivebelts. A bit tougher on V-type engines (which we're not dealing with here), but works great for inline engines.

For future reference, I use a thin coat dielectric grease spread around inside the boots to lubricate them so there is less chance of the boot bonding with the plug. A pipe cleaner makes a good applicator. When attempting to remove the plug wire I twist the boot back and forth a couple times to make sure it broke loose from the plug. And only then do I attempt to pull the boot off the plug. Absolutely never try to remove a boot by pulling on the wire., pull on the boot.

Strycker: have you pulled the codes. Detonation might have broken the tip off. That might indicate an injector problem or a hot spot or carbon buildup in the combustion chamber.

Whizzle. I doubt that a valve completely dropped Maybe a piece of seat or valve head. Other wise there is a good chance the engine would be locked tight. Like others have said, pull all the plugs and see what you have.

I've never pulled a code before as never have had a service engine warning or anything on the car. Would it show up without a code? As for detonation, it's never had a problem since replacing the Bosch with Motorcraft plugs. Plus that would have been on #1 cylinder. Just that tip on the Bosch blew and luckily didn't fall into the cylinder.
