    Hey guys,

    I have a 2004 Jeep Wrangler SE 5-speed with a 4 cylinder 2.4 L engine. I am trying to figure out what went wrong with my engine. It is pretty tough to find these 2.4Ls around (since they kinda blow), but I've heard there are a few possibilities of what could have gone wrong.

    I was on the highway driving while it was fairly cold out (30 degrees), probably going about 75mph. When there was a sort of popping sound and then the engine shook pretty violently for a few seconds and then everything cut off and I was just coasting, could not accelerate or anything. I stopped on the ramp of an exit and popped the hood. The engine itself had a hole in it and oil had clearly been sprayed all over everything around the engine. The hole was a little smaller but about the size of a fist. I tried to start it a few times and I couldn't get it to turn over. Any way, I got it towed to my house and let it sit for about a week. I went to see what it sounded like when I tried to crank it up and it actually started to my surprise and then shook like crazy to the point where I just shut it down. I noticed there was no oil in it and put a quart in and tried the same thing. Same result except oil flew all over the place under the hood through the hole. I don't know if I have given enough information, but I am trying to see if you think I threw a rod or if it could be a freeze plug or something a little less serious. What would you do if this was you? Preciate it.

    Sounds like a rod let go. If it was a freeze plug, coolant would have leaked out.

    Freeze plug would not throw oil...it would throw anti-freeze. Chris is likely correct that you threw a rod. The truth is, it really does not matter much at this point. Sounds like time for a new engine.

    Of course, when all else fails...post pictures. :worthless:

    I'm curious as to the outcome of this issue. While I am 99.9% sure you threw a rod, I'd like to know. I can't imagine what would poke a hole in your engine and spew oil all over the engine except for a rod. A broken valve spring can cause massive damage and I have heard of it happening but never making a hole.
