My GOD!, I hope you did not fill it up with Diesel Fuel!

But Seriosly, sounds like a case of bad gas at the pump(A) or maybe even your timing is off, like way off,(B) lastly, (C) you just lost your timing chain.

no offense but thats a pretty dumb thing to post. If the guy is asking this question he's probably not really sure what he's looking at in that picture, nor would he know how to tell if its properly timed, or what to remove to look at the timing chain.

Did it do it again, or only the one time?

Any one else ? got any suggestions ? .. could it be a effect of diesel like Silver suggested ? Two of the spark plugs were covered with oil......or gas not sure.... but i think its oil... they are just black ... and well my pullie bolt was loose ..... so i dont really know what to think....

Could be a valve not seating correctly(exhaust valve open at time of detonation), could be bad fuel, fouled plugs, timing jumped...

So, you ripped the engine out of the car after it started popping?

What year 2.4l? If it's a pre 98, it's got an EGR. I know this sounds funny, but I've had carbon build up in my EGR and cause it to pop, clog, smoke,... u name it does it. It's cause the EGR gets stuck open and lets exhaust gas flow into the intake at idle, causing it to drown in carbon. Sounds crazy, but it happened to me! Take the EGR off(easy chore) and clean it with carb cleaner and make sure the pin is opening properly before reinstall. It might not be the problem, but it's a good idea, just in case
Check your plug also, they're a good way to tell if somethings wrong!
