Spark Plug tips gone!!! UPDATE 2/6/2011

**MidnightBlue** · 12-28-2010

Its started out as a really bad misfire, couldnt figure it out, broke down along the road, got towed into dealership to tell me my spark plug tips are melted and gone. They wanted to bend me over and charge me 330 bucks to change plugs, dont even know why the quoted me. If anyone can help me as to what has caused this and if it will happen i put autolite 605's in now. i had Gm acdelos in. Here are some pics

Busted tips mean internal damage...your going to need a new bottom end...sorry to break the news to ya boss.

**MidnightBlue** · 12-28-2010

i dont think they busted, they burnt. cause you can see on the 3rd plug the tip was strting to get melted

**Bio248** · 12-28-2010

the only way they get burnt off is for them being in the car FOREVER or for your combustion chamber temps to be off the freakin charts high, which means you were knocking and running low timing.

**blueguy** · 12-28-2010

Something has the be in there flyin' around to cause the tips to be gone...like especially on the 2nd plug from the left...destroyed.

im back to a stock tune now, and i just did my topswap in september. I did have a knock in the drivers side of the motor. prior to my misfire.

**blueguy** · 12-28-2010

Yup...high compression builds NEED a custom tune...you can't run a "stock tune" on a Top Swap...prolly what did your car in.

**MidnightBlue** · 12-28-2010

i dont mean a stock tune, i mean we took everything down from where we had it

**blueguy** · 12-28-2010

What mods did it have on it when you top swapped it? What tune?

**MidnightBlue** · 12-28-2010

there are no internal mods just yet. so it is a topswap, with cai, and a custom tune, glanzergtx did my tune, he has the file

**blueguy** · 12-28-2010

No flow mods...on a top swap?

**shawngtp** · 12-28-2010

Oh boy here we go.

**MidnightBlue** · 12-28-2010

Mike...you NEED headers or some sort of exhaust mods...if not...there was your problem.

**MidnightBlue** · 12-28-2010

that is what i thought, because the front is the only one that got burnt, and i was thinking the heat isnt getting out quick enough.

**blueguy** · 12-28-2010

What exhaust mods do you have? Or is your exhaust totally factory?

**MidnightBlue** · 12-28-2010

all i have is muffler delete, cuz i wasnt getting enough flow, i would whistle

**blueguy** · 12-28-2010

Well...there is your issue. Muffler isn't the flowing issue...the factory manifolds/downpipe/u-bend are what needed to be replaced...you probably had KR out the ying yang...sorry man...but I bet you lost at least 3 pistons there. Especially with the factory AC Delco's...
