The car that I am working on displayed below is a 2002 Chevrolet Cavalier 2.2 DOHC. I would like to admit that my knowledge of cars is little to none. I decided to start tinkering around with it because for whatever reason the car would not start one day. I replaced the battery but while doing so I needed to remove
the part labeled '2' in order to get a socket wrench to remove the bolts going into the battery.
When I removed
2 black engine oil started pouring out of the part labeled
1. I know that 2 goes to the air filter but I have no clue why
2 are filling with oil nor do I know what they are called.
Please help me identify the 2 parts and additionally why they are filling with oil if possible?
