Bosche Nightmare(WARNING)

Okay, so my friend and I decided to change out the plugs on my GST. We went to O'rileys, bought some NGK's and proceeded to pull the Bosche plugs. Well we started on cylinder 1 and carefully pulled the 5 month old plug out and out of no-where the plug snaps inhalf at the base. I had never had this happen before and wasn't sure what to do but we finally rigged together an "easy out" system but never tried it though being afraid of metal shavings getting ontop of the cylinder. :banghead: So somehow we dragged the damn thing 2 miles up to the local car place(Jiffy Lube equivalent) and waited an hour for them to look at it and they wouldn't touch the damn thing without spending $2000 to remove the head(I overheard them charging someone $250 for some new plugs and wires and $400 for a fuelpump :disappoin ) so I knew it was bogus. So we got a tow-truck and took it to a local import shop and the guy there ended up riging up the same fuckin "easy out" system we did and he got it out in about 20 secs with no trouble(and with no charge). After studing the broken plug it turned out to be a manufacturer defect and it had been broken the whole time :uhoh: The new NGK's make my car backfire a little but nothing major. Right after all this I looked online and there are a lot of people that have had this happen with this company. SO BEWARE OF BOSCHE! DO NOT BUY FROM THEM!!!!

Thanks for the product feedback. I won't ever be buying those!

That would be really really shitty thanks for the feedback, glad that never happened to me cause thats the brand I use to use.

OMG, I would have probably freaked out if that happened to me!

Do you know what this "easy out" system consisited of, so just in case anything like this happens to any of us, we can gerry-rig up the same tool!

lol i just put bosche plugs in my beater car. Hopefully they will be okay. (if i ever change them again lol)

Before I knew better, all I used was Bosche plugs. But the thought of a plug breaking off gives me nightmares, glad everything worked out for you.

Yeah, what is the "easy-out" way?

When Monday comes I will deffinitely be calling them up about this.
The "easy out" system is this triangular piece of metal that embeds itself into objects so you can twist it out. Which we tapped to a wrench. You just have to be very careful because metal shavings can be dropped into the cylinder but thank God that didn't have to me. Every shop I went to yesterday laughed at me when I told them that it was a Bosche plug, so there is deffinitely something up with that company.

I had a Bosche plug break in my Oldmobile when I was changing them. Apparently they were over-torqued in the head. Wen I went to remove them, 2 of the cracked. It was enough there to still be able to get the socket around it and move it. Took a long time though.

Yeah dude, Mikes DSM had Bosches in when we got it and they got all good and fucked up. They didnt crack in half or anthing but the two pieces that the spark jumps between melted on all of them and the ceramic insulator thing cracked and broke off on 3 of the 4 plugs. Thanks for the heads up on the cracking in half deal. I agree, lets see a write up on this easy out thing!

Official broken spark plug removal/"Easy Out" system:

Tools needed:
1 "easy out"-I think mine was 3/8"
torque wrench or regular wrench
1 large or 2 small socket extender(s)
3/8" socket(use size socket as size "easy out")
hammer or small rubber malet
electrical tape
vacuum cleaner

Okay so some way in hell your sparkplug cracked,broke, or split in half inside your car and you are freaking out about what to do...There is an easy way to get it out, it just requires some pacients and time. Remember this is all up to your discresion and there are some risks associated with doing this wrong that could make you need a new engine! Do at your own risk
1) Start by vacumming up the surrounding area on the valve cover to get any debris off that could potentially get inside the cylinder. Second wipe off the vaccum hose and proceed to vaccum out any extra metal pieces inside the head by carefully placing the hose down into the head. Hopefully there will be none but just to be safe...
2) Attach the extender(s) to the wrench and the socket at the end. Place the "easy out" into the end of the socket and press it in firmly so it won't come out. And just to be safe wrap up the connection area with the electrical tape to prevent the "easy out" from comming out of the socket.
3) This is the fun part. Just take a deap breath and possibly pray that it will go okay :uhoh: Place the "easy out"/socket contraption that was just made down into the head until you reach the broken plug. Get the hammer or rubber malet and barely tap the top of the wrench until you feel the "easy out" catching inside of the plug. Don't tap it too hard to prevent any metal shaving(s) or pieces of the plug getting inside the cylinder. If you feel as if the "easy out" is in far enough start turning the wrench like you would when normally removing a spark plug. If at any time the "easy out" starts to loosen up just tap it in with the hammer again until you feel it catch again. Remember the point is to not get any metal inside the engine!! At this point you should be able to pull that bastard out of the head.
4) Next go back to step one where you would vaccuum around the valve cover and inside the top of the head to get any loose pieces of metal that might have come loose out. Shine a light down into the head to see if you can see any pieces left, hopefully there won't be any. A very small magnet can also be used to get any extra pieces. If you are really worried, an engine flush can be done.
5) Install the new plug(s)NOT BOSCHE, reinstall the wires, get inside your car(pray), and start her up. If it was anywhere like mine, it will run perfect. There's also a way to get any potential pieces out of the engine by leaving the affected cylinder with no plug or wire inside, putting a vaccum cleaner hose into the head and turning the car over. This should force everything inside the cylinder out and into the vaccuum cleaner hose. I didn't use that method, I was just told about it.

If you have any questions or comments just pm or email me and I would be happy to help.

I see this thread being a sticky in the near future :2cents: lol. Good info there endless

lol i was so pissed (im endlesess friend) that he rigged the same thing we had all ready did at my house...all that work for nothing...

I'm not liking these encounters at all... I have had Bosche plugs in my car for a year now... :uhoh: I think I know what I will be taking out of my car this week...

So what is the plug recommendation if not going with Bosch

Ngk Bpr7es

Good write up.

Didn't Martin have a thread about Bosche plugs that was a sticky awhile back?

Sometimes it's the simple jobs that go to hell. I had my car on jacks for days after I lodged my deep well socket in the spark plug cylinder. Then, a month later, it only took a few hours to swap in a couple grand worth of mods.

One crappy plug has the power to f' you up.

Delco or NGK are top notch plugs.

Bosch plugs are junk, we've had so many problems with people putting them on their cars at the shop i work at.

Ya, I guess we forgot this one when we were trying to get the old stickies back up.

NGK BPR6ES's for mostly stock cars NGK BRR7ES's for more modded cars

shit,i have those in my car now and have had them over a year,now i am going to shit my pants when i take them out,now if i bring it to a shop and have them do it its there problem right?so i will put the worry on there hands.

Not necissaryily, if you are that worried and going to have someone else change them, just go to a regular car shop that does spark plugs and act like nothing is going to be problematic. If one breaks it's not the end of the world.
