I think he meant the CEL didnt come on prior to the plug failure....

so lets get this sorted, your car had the older version pugs the faulty ones correct? so that could be a reason it failed, you did not have the newer upgraded plugs correct? now if the tune was bad and there was detonation you would think more than just 1 plug would show damage from the lean condition but you state that the rest of the plugs are fine and show normal wear correct? only the one plug is damaged and melted correct? and I assume it's in cylinder #5 where you state the compression was 30lbs, like you mentioned something in that cylinder has to be broken for it not to have compression, do you remember if it built up compression when cranking and then dropped or it never got over 30 at anytime, did they do a leakdown test? once the head is off you will know exactly what's going on and you should make the dealer prove to you how the tune could have caused this damage in cylinder #5 only, it sounds like they are just trying to get out of fixing it under warranty
you are right, i should argue with them more on how it affected only cyl.5
i found NGK spark plugs but same heat range which is 7

I had CEL and i stopped and directly plugged OBD2 scan tool and saw it is misfire in cyl.5, but didn't expect the plug to broke in, i thought its the same issue as the others are seeing.

why are you delaying parts of your story! Ali did the CEL come before or during the race?? i am sure you are going to say before 
come on so if the plug gave up for SURE the CEL is going to not only come on and probably going to be flashing all around too

bro all the best but its clear that you are not sharing with us everything and you are just putting together a story for us to believe its the plugs!! if i blew my engine i will share it with everyone so that no one falls in the same mistake and try to help others avoid my mistakes, here you are making a drama on the plugs but you want us to believe that you had a perfect tune!! because of your story i had my plugs checked again yesterday just to make sure nothing is wrong with them you are making us trip about whether they will hang around or fail. can you please post a pic of the rest of the plugs??

im not that careless to race if i felt there is something wrong with my car, and it was a random race
one plug failed, and it has to do with the white ceramic small part ( same as recall issue ).
blew the engine, braked it down, call it what you like, and if i was not intrested to keep you all guys safe from having an issue, i would have not opened a thread from the begining.
car was fine 100% untill that day i raced and CEL came on with viberation, to tell you the truth, even if you drive it now or idle it, the vibration is not that bad.
so what do you think i am hiding !!
bad tune cause it ? maybe !! who knows ?
i will take pictures of the other plugs and will post them here

good we need to see how they look like, here is how my plugs look like after 7000km which would be around the same age as your plugs plus we both drive our cars hard most of the time

If he wanted to hide something he would have not posted at all. After years on this forum I have realized that if you post about your engine issues; members will come up with their own supposition on what did or did not happen. They will also lay blame where THEY feel the failure occurred.
This is all fine since Ali posted it in a public forum (opinions have to be expected) but lets wait and see what the techs really say. The bottom line is if one mods their car, they better have the "pay to play" mentality just in case.
I wonder if some tuners are advancing too much timing---

we all drive those plugs in our cars if I had a problem I will share it so all the others would avoid it. If you go back to your dyno thread Ali mentioned how better the AFR is with the tune, so he must have asked for advancing the timing for more power and this is the consiquenses of his interference in the tune. I hope I am wrong but you must expect the argument on all possible couses. Sorry if this doesn't make some comftable, I like everyone with the V8TT would want to know!

We come in this forums to share info and benefit from our experiences, Ali is sharing the info but is updating us towards what he believes happen, the pic of the plug shows detonation! He mentioned melting and then blames it on his eye sight we all drive those plugs in our cars if I had a problem I will share it so all the others would avoid it.

This thread is a bummer. Looks like for the time being the CLS since its getting hotter in phoenix will live off a diet of 100 octane.
Really interested to see more pictures.

Sorry if this doesn't make some comftable, I like everyone with the V8TT would want to know!i did not ask for more timing from the tuner or anything, i have exactly what vic has on his car. and my AFR is richer than what i had on stock tune
techs will propably blame it on the tune even if it is a fualty plug.
and yet till now they didn't report to me on what is wrong with the engine
guess they didn't poped the head or used a mico camera.
if the bore is fine i will fix it and use NGK plugs and check them every 5k
head cost 7000AED ( about $1900 ) , each valve cost 140AED ( less than $40)
so part wise will be maximum $2500, but labor wise will be Total RIP OFF.
these are the prices if i have to pay. untill now, dealer didn't take a decision if it is under warranty will be fixed.

primary check up by dealer is that for sure the valves and cylinder head is damaged, piston ring and bore seems not affected ( i hope ) because they can't see it now unless they open up the engine and double check.
micro camera shows no affect on other parts.
will keep you guys updated as soon as a hear something new

If you unlucky it can get pinched between valve and valve seat or if squish is smaller than piece it will get stamped in to piston and sit there. I have never seen electrode damage cylinder wall, at least on motorcycle engine that I work on all the time.
Since compression is down on Ali's engine I would do simple leak down test and see where it is leaking. It will tell if exhaust valve, intake or piston. Simple test that points to problem.
