Weird thing happened. I was checking the oil-level and noticed that she would like a little bit. I removed the oilcap and i found some white/gray'ish sticky stuff . Does someone have any idea? I´m driving a 1996 1.8 8V sports with 75000kms on it. I just have replaced the oilcap with a new one because the old one was damaged and had cracks in it. Thanks in advance.
