i have been experiencing some p0304 misfire issues and 3x i have had my plug gap get closed . i was supposed to get a boroscope check done this weekend.
I was cruising at about 60mph no load just commuting home from work and i experienced some hesitation and then a bunch of rattling and then Check engine light. At this point the motor shut down and I exited immediately and put it in neutral and coasted to a stop. Where i had the car towed home/
I looked under the hood and didnt see any oil or spray, also i didnt see any smoke from the engine. I pulled the engine code and it was a p0304. I removed the cyl #4 spark plug and found this. Not sure if the head of the spark plug has made its way to the turbo or not, but so far it seems there isnt a thrown rod. This is my only daily driver, so I am pretty much screwed on getting into work tomorrow. I will have to call in and say i have car trouble.
I used mitsubishi road side to get it towed to my house. My current mods are drop in filter cosworth, grimmspeed 3 port, and a high flow cat, and a tune by evolution dynamics.
If the turbo and block are salvageable i hope i can minimize downtime and get it back up an running as soos as possible. In the meantime i can arrange for a rental car, or look for a cheap beater.
