I was changing my oil pan gasket today and when i dropped the oil pan i saw that over on the tranny side of the oil pan there was a whittish discoloration kind of like you would see if you had a blown head gasket but it wasnt everywhere in the oil i was wondering if it could be blow by contaminates, because it looked like it could have drained from my breather system. This is a boosted car and i know im getting blow by i just want to make sure what it is.
