I have two questions here. On the engine in my car (1986 300D non-turbo) there is a pump on the on the end of the cam. One of the tubes from this pump runs to a small reservoir that says OEL on the lid. I am assuming that that is oil in german, but what is the purpose of this pump and reservoir?

Any input would be greatly appreciated.

Thanks

Kurt Kiefer
