oil filter housing diagram

hey everyone,
I went to change the oil in my wifes 2009 aveo earlier, and the paper filter had come apart, i had to dig part of it out from the bottom of the oil filter housing, underneath of the plastic piece of the filter that had come off was a small black piece with a spring that was just laying in the bottom of it. I have been looking and believe that it may be an anti drainback valve? i was just trying to find a digram with how everything is supposed to go together since i don't think that i removed this part, i really want to make sure that it gets installed correctly. Thanks for any help!

pictures of yours? and i assume you mean oil filter? how long did you run that filter?

I was hoping you would be the one to answer this. sorry, i don't have a camera, so i can't post it. the filter wasn't even 2 months old. and it didn't come out with the cap, so i grabbed the filter and pulled, but only half of the filter came out, so i had to pull on the paper that was left as that was all that i could grab. the bottom of the filter seemed to be lodged into place, so i had to find something to pull it out with, and that is when i must have grabbed the anti drain valve and pulled it out of place. it has been reinstalled, and all is well, but thank you for the response.

thats why i was looking for a picture, to determine if the part with the spring is actually part of the filter or part of the housing.

so since you figured it out, how was it assembled?

Not to be a know-it-all, but having run a NAPA store for 5+ years, I actually do know this. The anti-drainback valve IS actually part of the filter. Attachment 4648 There is sometimes a spring that goes between the filter and the housing on one of these cartridge-type filters, but ours has the fingers which snap into place to ensure proper sealing of the filter, so no spring.

Happy Driving,
