Let me get this straight.

You buy a car and mod it, knowing good and well that it can and will void your warranty. Then you have a problem with plugs that were not original to the car in the first place and you want BMW/MINI to PAY for it? I'm sorry, but I stand behind BMW/MINI on this one. You replaced the plugs and it is a possibility that someone or you over or under torque them. In this case, why should BMW have to pay for a mistake not made by them? This is all you, good luck.
this is an on going problem with minis . i've gone out to check my plugs(for burn info) and found them loose. i always torque to 20 lbs. so for bmw (by now knowing this is a problem) to ignore this is crap ,.we need a site that just records failure of this nature so the staggering number of failures can be brought to the dealers .

over torqued or not, ive never seen a spark plug blow out of the head as many times as i have with these things.

helicoil it yourself. its not too bad of a job, but you may have to yank the head to do it, idk where those metal chips might fall if you do it with the head on. you might just be able to get away with changing the oil after drilling and tapping instead of yanking the head off.
run that plug up to t.d.c. then vacuum(A strong one)the chips out. should be fine.

I had stock plugs loosen-up, and then my aftermkt ones. I now check every 6 or so weeks, and it angers me that I need to do so b/c of their short-comings; b/c if I don't, I might end-up as this poor guy, which really sucks.

crzycpr, there is some good info here on NAM, and on Webb's site documenting this issue with earlier MINI's. Randy would be happy to share more details with you as it would give you sufficient ammo to plead your case. Best of luck to you!

Add/Edit - I now use Anti-Seize (just a tab) and I'm finding that the plugs stay put a little better. I still don't find this acceptable, and feel that BMW/MINI should do the right thing, and rectify this problem. But, it would be a costly fix for them, so don't hold your breath...
right -on brother right-on.

Spark plugs, whether stock and aftermkt, back-out in our MINIs. Again, it seems to be more so in the older ones ('02 & '03's)...

I was having an SES light (too rich code) for the last several weeks. No matter what I tried, I couldn't shake it (resolve the matter). After snugging-up lose plugs, the SES light disappeared, and after 3 hours of driving today (to Laguna Seca for the Monterey Historics), it did not return. I feel quite certain that the rich condition was caused by the spark plugs not being torqued properly.

You make a good point. It's realy hard to determine what the DME thinks when the plugs start to leak. This may or may not be the case with the older cars, they are older w/ more miles with loose plugs & blow out a plug ( they don't need to be that loose to cause a big problem ).
The plug of choice for our shifter karts was NGK ( even the KT100 pipe kart ). The Denso would loose crush ( as much as .003 ) for the first 2-4 TQ's, so on the road we used NGK. The good news is, the Denso, after the crush washer has seen a few TQs they are good to go.
This has been said many times, check your plug TQ often.

I had the same eject happen to me and this seems to be a big topic here. I found these guys online and they are great. I sent them my head after the inspection upon pulling it was that there is no thread left and they turned it arround in about a week for me.

Back taps and coils scared me into a long term repair with a one year warranty.

Good luck to all.
