GtipGary Posted April 28, 2008 Report Share Posted April 28, 2008 So im coming home from pizza hut earlier today, cars running fine nothing goin on. I pull into my parking lot and boom i hear a loud noise like somthing hit my hood. All of a sudden the pitch of the exhaust changes and the car starts running rough. I pull into my space and pop the hood and this is what i see... I tried to take a picture of the dent that it put in my hood but you cant really see it Is this something that can be fixed without changing the head??? i Tried tightening it back down but it just keeps spinning. Someone said somthing about a helix coil or some shit?? If i went that route how reliable would that be?? Quote Link to comment Share on other sites More sharing options...

Z34-5speed Posted April 28, 2008 Report Share Posted April 28, 2008 I had the EXACT same thing happen a month or two ago, it was even the same plug. What probably happened is that that plug wasn't properly tq'd down and over time it backed out. I got lucky with mine and they put a heli-coil in the head and i was good to go. If they can't rethread it or heli-coil it then i believe a new head is your only option. Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted April 28, 2008 Report Share Posted April 28, 2008 Geez with all these 3.4s popping plugs and snapping t-belts and 3.8s blowing up and starting on fire, I'm glad I own a 2.8 and a 3.1 jk guys Sorry to hear that man, hopefully it didn't wreck the head Quote Link to comment Share on other sites More sharing options...
ShockTherapy Posted April 28, 2008 Report Share Posted April 28, 2008 the LQ1 gods are pissed at you. get an iridium plug and a new plug wire, jb weld it in, and sell it to some sucker kid for 3,500. Quote Link to comment Share on other sites More sharing options...
GtipGary Posted April 28, 2008 Author Report Share Posted April 28, 2008 I dont think thats its worth 3500$ anymore tim... and i called a mechanics shop very near to my house and they said that they are gonna try to rethread it and then J.B. weld it in. They said that that is the only way that they can guarantee that it will be reliable. I just went to Advance and got a Bosch Iridium plug (they were out of the NGKs and This one had a longer warranty) I figure if that bitch is gonna stay in there it might as well be a good plug. Grimlers said that theyll do it for 150$ tomorrow... so well see what happens. Quote Link to comment Share on other sites More sharing options...
jeremy Posted April 28, 2008 Report Share Posted April 28, 2008 you're going to let someone JB weld in your spark plug???? Quote Link to comment Share on other sites More sharing options...
GtipGary Posted April 28, 2008 Author Report Share Posted April 28, 2008 you're going to let someone JB weld in your spark plug???? I dont know what to do... hence the reason i started this thread and asked you guys! The only thing i know is that it needs to get fixed because i have to be able to get to work and back every day!

krenzy Posted April 29, 2008 Report Share Posted April 29, 2008 JB Weld is no. No no no. They gave you two very good options: Helicoil or new head, in my honest opinion. Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted April 29, 2008 Report Share Posted April 29, 2008 Think of how much more your screwed if that JB weld gets down into the engine! A head will be the least of your worries... Find a new shop to take it to, any shop that suggests using JB weld doesn't have a clue what they are doing. Even the shop I used to go to wouldn't suggest that, and they are cheap bastards.

Andrew Posted April 29, 2008 Report Share Posted April 29, 2008 i would heli-coil it. you are gonna have to pull the head though, as you dont want metal flakes getting down into your engine when they drill out the plug hole. Quote Link to comment Share on other sites More sharing options...
BXX Posted April 29, 2008 Report Share Posted April 29, 2008 i would heli-coil it. you are gonna have to pull the head though, as you dont want metal flakes getting down into your engine when they drill out the plug hole. vacuum cleaner or the like with a thin long attatchment Quote Link to comment Share on other sites More sharing options...
GP1138 Posted April 29, 2008 Report Share Posted April 29, 2008 JB Weld is the beginning of legendary forum stories. Seriously, stop freaking out. It'll be alright. Helicoil, and do it right. Carefully, and make sure it's straight. Quote Link to comment Share on other sites More sharing options...
Venom Posted April 29, 2008 Report Share Posted April 29, 2008 JB Weld is the beginning of legendary forum stories. Seriously, stop freaking out. It'll be alright. Helicoil, and do it right. Carefully, and make sure it's straight. Ditto, I know you want a quick an easy fix, but the only route you really have is the helicoil. Remember: if you dont have the time to do it right the first time, when are you going to have time to fix it again. Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted April 29, 2008 Report Share Posted April 29, 2008 Geez with all these 3.4s popping plugs and snapping t-belts and 3.8s blowing up and starting on fire, I'm glad I own a 2.8 and a 3.1 jk guys Sorry to hear that man, hopefully it didn't wreck the head Don't consider your engine exempt, I know of at least two 3.1s that spit out a plug, both times it was the center rear one, a real bitch to get to.

Euro Posted April 29, 2008 Report Share Posted April 29, 2008 Damn, you 3.4's are destroying hoods! See, at least when the 3800's go to destry hoods, they do it to the EXTREME!!!!!!!!!!!!!!!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted April 29, 2008 Report Share Posted April 29, 2008 Damn, you 3.4's are destroying hoods! See, at least when the 3800's go to destry hoods, they do it to the EXTREME!!!!!!!!!!!!!!!!!!!!!!!!! Yeah, they destroy the entire front end! What would cause something like this to happen? Weakened threads on the head or plug? too much pressure building up in the cylinder? Makes me wonder if there is another issue at play if this is happening... And its kinda freaky that its happened twice in the last few months to 2 separate members... Jamie Quote Link to comment Share on other sites More sharing options...
GOT2B GM Posted April 29, 2008 Report Share Posted April 29, 2008 Just make sure the plugs threads are clean upon installation. and that they are torqued down to the proper 15 ft/lbs. I always use a dab of copper antiseize as well. Quote Link to comment Share on other sites More sharing options...
krenzy Posted April 29, 2008 Report Share Posted April 29, 2008 <-- hates that plug with a passion What's wrong with the rear middle one? I never have a problem getting to it...of course I have freakishly small arms and fingers so....just lean the engine forward, remove alternator, and get that bastard out is how I do it.

meltboy1 Posted April 29, 2008 Report Share Posted April 29, 2008 ya, it's not toooo bad on the 3.1s... but the 3100s like my malibu... ugh... Quote Link to comment Share on other sites More sharing options...
jeremy Posted April 30, 2008 Report Share Posted April 30, 2008 so........................did you let them JB weld it yet? Quote Link to comment Share on other sites More sharing options...
89GP_SE Posted April 30, 2008 Report Share Posted April 30, 2008 why wouldnt you just go to a pick and pull and get the head, its not like its the rear head, the front head is so much easier. probably take you an hour or so to get it out of the car at the wrecker and then another hour at home?

jake63 Posted April 30, 2008 Report Share Posted April 30, 2008 More than likely the plug was crossthreaded at one point and the weakened threads finally wore out. Helicoil is the way to go, it will be a stronger thread than it was. Don't let some half-ass garage charge you to JB weld a plug, by the way, were these guys wearing mickey mouse hats?
