This is a follow up to the thread about Trouble code and scary ass sounds.... Post #1 in there has a back story.

Anyways, so I pulled my plugs today, first thing I was going to check to see what is going on. And I found some really shitty stuff.

This is the first one I pulled. When I went to pull the coil pack, the whole thing just came up. No unscrewing of the spark plug necessary. All the way over on passenger side, I believe this is #1. Magic #1. **** #1. (corrections in italics )


The camera couldnt really focus, cuz it sucks, but if you look here you can see that part of the insulator on the spark plug broke off.






You probably cant see it here, but the threads on the spark plug are just about 100% stripped. Like the spark plug was blown out of the cylinder. Also, by looking at how the boot is burned and split, it looks like it really was blown out. I also can not get the plug out of the boot of the coil pack. Awesome.




I tried to get a couple of shots down into the valve cover with a flashlight, but the camera still sucks and wont focus.




Here is cylinder #3's coil pack boot... something tells me the oil that is splattered on there probably isnt good.


Lookin down into 3 before I pull that plug.


Here is a look at spark plug #3, as a reference.




Here is a look at the top of the other two coils... Everything in there had this thin white dust film over it. I am guessing that is bad too.


OK, so. I am betting that just about any dealer I take this to will find a way out of warranty. "You were using spark plugs other than what came with your car" "You have an intake installed" "You are 24 and probably drive too fast" etc etc etc... I will probably take it by just in case, but I am preparing myself for not getting a bit of help to fix this thing.

So. If I do have to rebuild this myself, I am guessing I'll need a new head, pistons, sleeves, coils, gaskets, valves (maybe?). I am thinking that whatever happened is super BAD and the spark plug coming apart a little probably is going to batter the **** out of the sleeves and valves.

Thoughts?
(sorry for the long ass post, I want to inform everyone as much as I can to help me out here...)

 

it it just blew the plug out, you can helicoil a new thread in there, id get a boriscope and inspect the the piston and cyl walls.

 

Left to right looking at the motor starts at 1 btw. #4 is on the driver side.

 

lol ok, well **** #1 then

 

Hmm that could go either way. I'm mostly concerned about how #1's threads are stripped and how it was blown out of socket. I dont know what would cause that. . . i want to guess a result of leaning out some how? seeing as how white the plug is?

 

I dont know man, I thought I was pretty light on the mods side. I mean the only real engine mod I have is GM Stage 2, but something went wrong. That is for sure.

I'm thinking that at the least its going to need a new head, but I dont know if you can fix a head that has been blown out like that. And if I am in there for a new head, then lets do new pistons, and if I am doing pistons then why not.... and on and on

 

theres a 0 mile lsj engine for sale on rlf..lol. not to be insensitive haha, that sucks i'd go to gm first though and throw a fit.

 

well if its JUST stage 2 you have. . . . . . . . . . warrenty?

 

is the #1 coil ******* melted on the end?

I had oil on my 3rd spark plug and they just replaced the gasket and told me the white film I had was nothing.

Then 3 weeks later my car turned into and SS with the STI exhaust and my #4 ended up having zero compression and died because the #4 injector they installed from the GM stage 2 kit was bad.

Thank god for warranty they put a whole new motor in it you might be on that path but I don't want to say for sure.

I just really want to know why that #1 coil is melted on the end....

 

Do you have the stock intake? If you do throw that back on. Give them as little to bitch about as you can. I always save my last set of plugs, did you?

 

especially on the cold side of the plug lol. . . . Had to have happened when he turned the car on and when it sparked it mustve just blown up!

 

Technically yes, I have a warrenty. I am just guessing with the state of everything right now that any dealer is going to try and find something to point the finger at. And I dont have the time or money to fight GM about it, I bet they still pay their lawyers well, even though the rest of the company is crumbling. I will take it to a dealer first, but I am almost sure they are going to turn me away. They'll point the finger at the spark plugs or the intake, I am sure.

How long ago did that happen? I have had stage 2 on my balt for like 20,000+ miles or so.... How long did it take that part to fail?

Yep, still have it. I have the last set of plugs too, but man these plugs have been in long enough to where I Was about to replace them in a tune up anyways. But yes, I have the OEM plugs

 

5,000 Miles. The dealer said as of now there notorious for failing and he has had to replace like 6 motors already this year.

 

those are the wrong spark plugs for that engine. goes downhill from there

 

Really... I wonder if its the same problem. If I could get out of rebuilding this thing on my own it would be good. I will mention that to the dealer.

Speaking of which, I need to find a good dealer around here. The one in Denton isnt my favorite. Last guy I dealt with was a dick.

 

yup, the will say you cross threaded them putting them in, and its all over, but like i said, it CAN be repaired.

 

This is what i am afraid of.

x2 afraid of

 

Another thing when you take your car to the dealer clean the inside very well, don't leave any time slips or any other types of racing paraphernalia, not even a track flier in the glove box. If your dealer is a dick i wouldn't put it past them. I think for the most part if you just throw your stock intake back on you won't have much of a problem with them. Right now some dealers are just happy to have work to throw out to their techs.

 

If you haven't taken it to the dealer yet put the stock plugs back in includining the one that blew out. Mine did the same thing on #3 with one step colder plugs, they tried to get out of repairing it by saying they wern't torqued to spec. Well I had one of their techs replace the plugs so it ended up being their fault and the replace the head under warranty. Good luck

 

I cant get the damn plug out of the coil, its like fused in there

 

heh not if its coming out of they're pockets, and the way the economy is, man I would do everything I could to go back to stock, stock, stock. Because they're already about to go down the *******. good luck.

 

we did that and the spark plug blew and ruined the thing that is connects to...why can I remember the name of that part....anyway we got it fixed and no it wasn't covered by wannenty
it cost about 500 to 600 cdn to replace

 

You just got the coil pack replaced? You didnt have to get anything else done?

 

It doesn't come out of the dealers pocket. It comes out of GM's pocket and if they don't send an inspector out witch they rarely do is all you have to worry about if the dealer wants to do it. Something this small would not throw up a red flag.

 

for 1 never put those kindof plugs on any car...does not make it faster beeter burning or anything..its a hook to get u to buy something u think is better....also did u gap the plugs right??? NO SPARK PLUG IS PRE GAPED..even if it says so it takes just one jonny to drop the package during shipping the **** them up..and all 3 sides would need to be gaped near perfect to .040. the white is from coolant.
