Sparks coming from exhaust?
Sparks coming from exhaust? I had a guy tell me yesterday that there were some sparks coming from my exhaust. Im not sure if there really was or not but if so what could it be? This was on 175 shot and the car still runs good. The exhaust is some pacesetter headers which are fairly rusted and a lanes performance true dual system.

I have lost a tip or two and only noticed a rough idle. The LS1 ignition is pretty good to cover that stuff up. I have also destroyed plugs and had misfires as well.
As long as it didnt take a portion of the valve and seat with it...your good. But Id pull em and check em. If they are burned...you have 8 lives left....lol. Thats about as close as you can get without some serious damage. Youll need to adress the underlying issue.

Couldn't the glowing debris at open throttle under nitrous be any carbon build up within the combustion chamber or early exhaust breaking free and shooting out while being super heated? Considering the nature of spray I can understand wondering if it is molten engine parts but to me, exiting red hot carbon deposits seems logical too.

Ive been waiting for a thread like this. Ive melted a total of 4 plugs at different times. The car seems to run just fine. I can never tell when its happened. If really freaks me out because i can never tell when it happens. Im in the process of figuring out why it happens because it cant be normal. I have a thread on this and some of the guys are pointing at possible weak valve springs causing valve event to be off and detonation. I really hope thats not the case. I just had the heads off.
yep..when detonation happens it has effects on so many components. Sometimes it will make "pits" in the cylinder tops...or even the quench area of the cylinder head. Its very odd looking. Looks like impact marks from a sharp object. Many assume something went through the cylinder chewing it up....but its just detonation.
ok...so the plugs looked good. Thats a good thing.
Is this a clutch car...I have also had sparks fly out of the bellhousing launching with scintered mettalic type clutches.
But if your plugs are perfect...your probably ok.
Also...you can get fireballs out the exhuats on shifts if you have some fuel delay (oppositie of the lean spike) or are just rich in general. Nothing really wrong with that either.
