Today I started to replace my alternator in my 84 turbo. After getting it out I noticed that the entire alternator was covered in black or dark grease/oil. I used some engine foam degreaser cleaner to clean the PS pump area as well as everthing near it to find the leak. Has this happened to anyone? Iam not sure if its a cam seal or power sterring leak. I have not checked my fluids yets because the car is up in the air on jack stands.I will check them later.
