Xmas Evo Failure
Okay... I was driving home from visiting my parents for Xmas. About thirty miles out, I had a huge backfire and the engine started to misfire. Luckily I was close to an exit, where I was able to get the car parked. I looked to see if I were leaking fluids or any parts missing and found nothing. so, I decided to look underneath the coil cover and found one of the packs completely destroyed. After I removed the damaged pack, I found the #4 spark plug loose. It appeared that the plug was shot out of the head into the pack ( I tried to put in a new plug but, there seems to be no threads in the head).
Has anyone ever heard of such a thing happening?
Over 85miles from home, the car has to be towed, and it is snowing... Merry freakin' Xmas.
Noted, on the way to my parents, I had an intermittent issue with the car sputtering whenever I got the car close to 80mph but, eventually the issue went away. The same thing happened before the 'fail'.

As for pulling the plugs and checking them.... I have not gotten to it yet ( also, not enough light at the time of the incident. I will pull them out later on today ( if it stops snowing ) and post pics.

You might be able to save the head using a helicoil or having a machine shop fix it. I dont think you would have to replace the head but then again we cant see the damage that was caused.

Seen several times. The plug was not tight. Aluminum heads only. The plug is of course steel and it over time being loose worked on the threads and had nothing to hold it in. The tip of the plug looks good, not detonation. If you lived closer I could repair w-o removing head.

Happened to #3 for me a few years back. Was fine, stopped at a light and when I went.. POP.. ran on 3 cylinders. The plug actually shot up and cracked the plastic piece that is on the valve cover. I was fortunate enough that the block was still hot enough to get another plug in with only minor damage to the threads on the head. Just make sure those plugs are tightened down.

Normally I get all of the work on my car done by Atlantic Motorsports in MD. but, my job requires a lot of travelling so, I visited another tuner (name shall not be mentioned), located where I was at the time.
