Looks like the beast was definitely a little hungry. Nice job on killing the plug. What tell-tale signs did you see on the other plugs?

Nothing major on the rest of them. They all looked fairly normal, but again, only had 1000 miles on them.

Rod Rounds diagnosed my previous set at WCBF as not cold enough. I think he'* right.

By the way, in case you can't tell in my pic, this plug is MELTED off.

those babys got WAYYY to hot.
At the rate you change plugs, Autolites it is.
And the ticking you have is most certainly a damaged/collapsed lifter.
It ticks at half the speed of engine rpm it seemed like from the video you made.

That'* my bet at this point as well, from the front cylinders. It never missed a beat though, which had me thinking spring. Lifters will occasionaly NOT tick when collapsed.

Lifters are on the list along with all the other goodies. Springs, pushrods, xxx, xxx, xxx and possibly xxxx.

Hydraulic lifters make good oil filters too, however, the second something jams one up, it will tick, my park aveune was like that, however, that was on a very tired valve train, and a poorly maintained engine. After an oil change the tick went away for a while, then came back.

She took alot of power though before something gave in, that in its self, impresses me.

Ahhh now were gettin somewhere..
I know you wouldn't upgrade either of those (non xed) things without doing at least one other thing.. And I can't see you not doing one other with the heads off..
Should be an exciting spring?

I had valve float for over a year. I've needed stronger springs since the day the JET pcm went in.

Bill,
why not try to gap 1(one)NGK tr7-ix or tr8-ix(very cold plug) out to
.050" or .052". i have so i know it can be done, you just have
to be real careful with the center electrode you don't want to
put any sideways pressure on it. with one plug in the front bank
you can drive a little bit and check the color. tech'* i have spoken
with report no problems using iridium plugs with Nitrous or Supercharged
engines.

ROD

p.*. just put (1) tr7 or 8-ix in the front with 2 of your regular plugs. LOL

Rod, my tech chat with NGK a couple years ago confirms irridium is fine in Supercharged or Turbo applications. But the frequency I change plugs (especially when tuning) dictates my budget. Copper plugs are a fraction of the cost.

Upon further inspection this morning, I found evidence of the #6 plug starting to go the same way.

I would boroscope the cylinders and check the status of the pistons if it were my car. The older motors before Hypereutectic pistons could survive detonation a bit better and would melt plugs long before the pistons cracked but to be safe I would examine them.

That is definately detonation at work.
