I am replacing my alternator and had to take off the vacuum pump from the back of it and there was oil in it. Is there supposed to be oil in it. I clean the oil up just to see the parts clearly. If there is supposed to be oil in there should I put a little clean oil in there since I wiped off all the oil that was in there. I am assuming the new alternator will not come with the vacuum pump attached. I appreciate the help.
Thanks
Billy
