Horrible Fire!

Ok, fresh remanufactured chevy 350 everything basically new in my nova. Just got it on the road a few months ago. I have been hearing a ticking sound like fire jumping. Fired it up today and it is missing... rough idle, smells rich. Pulled the no.2 plug, gas ran out of the plug hole. Put the plug back in....waited till it got dark started it up. You can see 7 of the 8 plugs including the no.2, sparking through the ceramic right next to the metal base. Is this normal !?

Thanks!
Doug

That is hardly normal. Do you have a good set of plugs and wires installed? With gas standing in #2 cylinder, that is an indication that cylinder is not firing at all. It could be plugs, plug wires or a problem in the distributor or coil. List what ignition components you have. That is a good starting point so we know what to work with. I would be careful starting and letting it run too much until you track down the problem. If the cylinders are holding gas, that means the gas is washing down the oil and will cause major ring damage.

Thanks for the reply. New ac delco plugs r45ts, new wires set (from autozone), the distributor is new, it is one I bought off of ebay, generic brand supposed to be high performance distributor delivering higher voltage. (maybe to many volts?) this is the distributor ----->


http://cgi.ebay.com/ebaymotors/ws/eB...m=120207727677

I am already thinking of a new set of plugs and high dollar wires. Any suggestions? Could the timing be off? It is set at about 10dg/btdc....

Check and see if your new distributor is made by "ProComp". It seems eBay is getting full of this cheap Chinese junk (stay away from anything that says ProComp). Is this an HEI ignition? Even if the timing was off a degree or two all the plugs will fire. Double check the plug gap.

I hate to point out what sounds obvious, but any chance you cracked the insulators installing the plugs? Easy to do, hard to see.

Good point... I'm always careful of that as I have cracked a few in the past. But I can't believe I have cracked 7 out of 8. It doesn't look like its arcing over to the base, it just seems like you can see the fire going on inside the plug. Very weird....

Very weird indeed. But if you can see spark it is more than likely bad plugs,whether or not you cracked them doesn't matter. Change them or if budget is tight change 1 to compare it with others and see if that new plug still shows fire.Then go from there.At least this info will give us more to try to help you. Good luck.

For starters try this small test. In pitch black darkness and the engine running, pop the hood and take a look, you'll likely see spark leaking all over. Throw the autozone wires in the trash, these are usually high resistance solid core junk wires not suitable for use on a lawnmower. MSD, Moroso, Taylor, all make spiral core wires and while you'll pay more for them you'll get what you pay for. Don't buy anything with accel written on it either. I would make sure the new wires are fully seated and would coat the inside of the boot with the grease that comes with the wires. The next step is routing them correctly, dont let the wires cross one another and keep them at least a half inch away from each other. It sounds like now you have cross fire issues. Remember this, electricity is lazy and smart, it will always take the path of least resistance, whatever it can find thats a lower resistant ground it will take, so if the spark can leak to another wire thats closer and arc to the metal near the spark plug itself, it'll do it.

My last set of MSDīs plug boots melted so I will not be buying another set of those, I also tried Taylor but they went hard.
Took them off the motor and they retained their "set", which led to the outer covering cracking.
Iīm going to try some Crane Firewires.
I also use as many wire separators as is feasable to avoid crossfire.

My guess is that you some conductive material on the plugs and the spark is taking the path to ground on the outside of the insulator.

Did you gap the plugs. If the gap is not correct (to wide) it can sometimes force leakagethrough an easier path. I would also be wary of autozone branded parts. A good set of OEM wires, or MSD's would probably be better for you in the long run. Cheap parts hardly ever pay off. If you can see it on 7 of the 8 cylinders I would be real suspicious of the wires. D you still have your old ones, you could try swapping a couple.


All plugs need to be gapped. There are no "pre gapped" plugs. The same plug that requires a .035 gap on one application may require a .065 gap on another. Always check the gap before installing, it only takes a minute.

If fire is jumping from the porcelin to the metal base....its simple...the porccelin is cracked ( sometimes the cracks cannot be seen by eye, but you do have fire coming out so they are cracked). Go get some more new plugs, use a proper plug socket to install them with and do not overtighten.

They don't get better than MSD, well maybe Magnacore. If you melted the ends you have serious heat issues.

I'd bet the cheapo autozone boots are leaky or you got gas ll over everything.

If you 'have gas pouring out of a clyinder' you have a leaky carb, and WILL score the clyinders.

I really doubt you can fill a clyinder on a running engine just by being rich or not firing
