Tip of plug broke off!!! Misfire and white smoke Car started missing last night..Pulled the plug this morning and found that the tip of the plug was broken off..Put another plug in and still misfiring..Its getting spark with the new plug but is still smoking and reading "misfire cylinder 5"
Any ideas on WTF could be going on?? Could something internally messed up due to the tip of the plug breaking off??
EDIT :: BLUE SMOKE (which is oil correct??)

You _REALLY_ need to get that tip out. There is no way for it to fall into the oilpan because the Piston is right there under it and is most likely bouncing around scratching the **** out of your block. I suggest pulling the head so you can check for any problems that could have occurred. I suggest NOT starting the car until you can get the head off and check. You could get "lucky" with a magnet or something and fish it out through the spark plug hole, but you need to check for damage.

I got lucky and got the tip out!! haha
but its still not running right..still reading "misfire cylinder 5"
wtf is wrong with this POS?? Brand new plug, and plug wire..Highly doubt the coil is bad cause the plug is sparking like a ****.....

Im going to go with the post above and say you should prob pull the head. With it bouncing around and getting slammed into the valves/block/piston could have really damaged that cylinder.

Check the compression and see what is going on. If the compression is ok do a leakdown test. Sounds like something broke and damaged the plug. Sounds like its time to pull the HEAD. But do a compression test anyway. White smoke is definately NG. TOM

Checked the headlight fluid it seemed fine
This was posted by my buddy who has a 02 Escalade. Its the LQ4 6.0 Vortec motor with a Paxton blower.
Guess he was hauling *** last night and the trans didn't shift and it was pegging rev limiter right before this all happend. Following this he drove approximately 10 miles before finally shutting it off for the night.
Went and checked it out tonight and it is most definitely internal problems. I don't even think a compression check is needed LOL..The coil pack, plug wire, and plug have all been changed with it still throwing the same misfire code.
What the hell would cause the electrode to break off like that though? Would the lifter have snapped it off due to the over rev?

My buddy got it checked out today and they told him "the piston shattered and cracked the walls"
Guessing there talking about the cylinder walls..Would this mean he has to get an entirely new block? or could a bore of the cylinders do the trick? Probably depends on how bad it is correct?

i just had the same thing happen to the GTO. no good way to do it with out breaking the bank. if the blocks junk just start over. if its not you could just throw some forged pistons in it and check the tune and fuel system to see why it leaned out. def has to be a melted or broken ring land.
my fix. 454lsx. NA power all the way. that **** wont happen again. 15k later i wont burn anymore pistons from running to lean under boost.

damn 15k is breakin my bank haha, Im not sure if i should stick with a stock block since im only running around 4lbs of boost. Or if I should buy a stoker kit and put forged internals. Im not really planning on raising the boost. I need something reliable since its my dd.

you can build the motor you have for alot les than 15k. you could do rod bolts,(rods if you wanted) pistons and never have to worry about it again even if you wanted to put more boost on it. id just double check your tune and make sure you arnt leaned way out at WOT.
