Engine Noise problems of the 2001 Dodge Intrepid

I was simply driving down the road and my car made a noise like air was being released (something being depressurized) and then my car would not accelerate. I had to turn into a parking lot and coast to a spot where I stopped. I opened the hood and my engine had a hole and a huge crack throughout the top of the valve cover. My car has less than 75,000 on the engine and has always had the oil changed at least every 3000 miles. I also noticed some sludge material on the inside of my oil cap when I was looking around. I can see into my engine through the hole. Repair man said repairs could be in excess of $6k. Car is still at garage as I ponder my choices, since I still owe over $3k on it.

The car was making a sound. Had just previously had an oil change. Got ready to get in the car to take to shop to find out what the noise was & the car would not start. Had to have the car towed to shop. That's when I was told the engine was gone. 5-6 thousand dollars to repair. Cannot afford that when still paying car note.

Pinging noise from engine, by the time I got home the timing chain broke the cover. Car towed to Dodge dealer where they indicated it needs a new engine. $7-8000. I noticed a fair amount of sludge in the engine and found similar complaints for the 2. 7 engine in the Intrepid.

Aug 21 engine began making noise, I took it to dealer on Aug 22, told engine was sludge up need to be rebuilt.

While driving at approximately 65 mph the motor ceased to function. It began by making a noise. Then the vehicle lost power. There was no power steering or power brakes. Consumer had the vehicle towed to dealer, and was informed that the timing chain blew apart, and there was no compression in the cylinders. Vehicle never indicated that it was running hot.
