Well, it was the #1 cylinder, as I had figured. I pulled the plug and saw something I've never seen before.

I wish I had a digital camera to show you guys, but maybe you can understand by my description. The inner "ceramic" portion of the plug...the part that has the tip on top of it...was separated and had slid all the way up, over the tip and had grounded itself to the ground strap. Voila! Dead miss.

I actually thought that there was no plug gap to it and that the tip was completely smashed, but when I started handling it, the ceramic portion slid back down and uncovered the tip. Crazy. Guess I got a bad one or something.

I had a spare Autolite plug and threw it in. I checked all the rest of them and a few were fairly fouled. I just cleaned them up the best I could and regapped all of them to .045. I was previously running .055 with my MSD Digital-6 box.

I started her up and she purrs like an kitten. Well, maybe more like a pissed tiger. :D I took her out for her first "long" drive in 6 months...went over to jmhardin's house...and she performed flawlessly. graemlins/hurray.gif

I'm so happy. Thanks for all the help guys! Can't wait to put some more miles on her and get back to the track!

:cool:

Many times a plug will crack the upper body and will cause a misfire. The tip of the plug often look fine however close inspection of the will show a harline vertical split with
carbon tracking. If you can hang your fingernail on the black trace its definitely misfiring there. This type of plug failure is often caused by plug wires that need to be replaced.

Glad you found it...

Justin, Glad to hear it wasn't anything serious! I'm never as lucky as that. :( Enjoy.

You get out of the dog house yet? Oh, and when you come back would you get me one of them bellhousing gaskets? :D

Thanks for your help last night.

You are SO lucky.

If it would have been me, the insulator would have split in two, fallen into the cylinder, scored everything to hell, smashed into smaller pieces, gotten up in the valves,.....

I'd be burning a bunch of oil now, no compression on that cylinder, and I'd be backfiring through the exhaust all the time.
