Oh yes especially in the winter. What come out looks like when you have a bad cold and you blow your nose--that color. Been running cans on the 6.2 DI truck motor for 2 years and 40k. The Vettes C7 and Z06 have not been in the cold yet but it is just like anything metal going from hot to cold. The inside of the motor is no different as well as the plumbing doing in and out. I have posted pics before of the winter stuff that comes out of the cans. FWIW does the same with my other vehicles that have had cans. The 2013 Jeep JK was one of the worst in the winter.Don't see where condensate would be a big problem. Don't know what else your getting to make it cream colored but would be nice to know if not oil.
