Speed Control Springs Problems of Chevrolet Cobalt

Replaced all of the following components since purchase: both front lower control arms due to bushing failures; both front shock and strut assemblies due to shock failures/leaks; both sway bar links due to failed components; both front sway bar bushings due to dry-rot; both front rotors due to failed/warped components caused by defective brake calipers; harmonic balancer due to defective/weak component; both rear shocks due to failures/leaks. Still need to replace rear coil springs due to weakness, all wheel hub bearings due to unstable driving/steering and the vehicle speed sensor causing high idle and erratic idling after warm-up.

Sitting at a turn light, cars started to move and I started to accelerate when I heard a loud pop noise (was not going over more than 10mph). So I pulled over and looked opened the hood to find my oil cap, filter, a black piece, and spring had popped out of the oil filter location which was in the block. Oil had been spewed all over. I took the oil cap to a Chevrolet dealership and the service guy said he had never seen the oil cap and filter pop out of the block, he examined the cap and only noticed one minor break in the threads of the cap. He said that the black piece and the spring that go in the cap must have failed which in turn cause the cap to pop out of the block, he also told me to look at the block to make sure it was not cracked. I then inspected block to make sure it was not cracked, which it was not, and had a new cap, filter and oil installed.
