I have a lot of oil that has leaked out under my air cleaner. I was wondering if anybody has a diagram of the parts associated with it. Car is an 81 300d non turbo. the air cleaner part # is 011 094 74 02, if that makes a difference. There is oil from blow by in the air filter. The bottom of the air cleaner assembly is covered in oil. Just started cleaning to see where it is coming from but no answers yet.

Thanks
