OK... as most of you know, changing plugs is supposed to be easy on the Mark viii right? Well I went to change just my plugs this morning on my 94 and DAMN! 6 of the 8 plug wires were not too bad to get out, but the other 2 are a nightmare! One of the cables separated from the boot and was left attached to the plug. Luckily I was able to get my very deep 5/8" socket to grip the hex on the plug after using a hammer to tap it down into place. The biggest problem I STILL have is one of the rubber parts that actually seals the porcelain section of the plug broke off of the end of the boot and is stuck HARD to the plug itself down in the plug well. With the rubber piece still attached to the plug, I cannot get the socket down to the hex on the plug. Any ideas on how I can get the rubber piece off the plug without having to remove the valve cover? This sucks, simple 15 minute job my A@*! When I do finally get them out, I am going to use liberal amounts of dielectric grease around the rubber body of the boot and plug itself to hopefully avoid a repeat in the future. So I plan on getting the Ford racing wires and Lightning plugs from Max but I still need to get that rubber piece off the final plug so I can remove it. HELP!!!

Since no one answered, I figured I would close the chapter on this one myself. After about 40 minutes of picking the rubber piece out with a old fashioned coat hanger, SUCCESS! You have to be patient and loosen it up enough to be able to hook it and lift it out. For those who have yet to change plug wires, be prepared for problems removing the old ones and have a tube of dielectric grease on hand in order to install the new ones. cheers!

I read this and said "sh!t, that has to SUCK" I'm glad you made it though.

Oh, and I used a metal coat hanger recently as well, to hold my moms Buick Century's muffler back up, she caught it backing up and ripped the weld.

I also had a problem someone left for me. I put new plugs and wires in my 96 when it had about 77,000 on it. I found out someone replaced the plugs already.
On the last plug I had to replace, the similar thing happened the bottom of the rubber boot broke off and someone left it in there. I was lucky enough to tap the socket on farther and got the plug out I was a bit nervous about tapping the socket on these haeds , but no damage was done.
