I have a Husky upright, not the great big one, but the one about chest high.
Two cyl compressor. I bled the tank today, and got water and a white milky
oily fluid. Checked the dipstick, and it is low. I'll get some Husky oil
today and fill. Do you think I damaged the compressor? Is the white oil in
the tank normal?
Ayup, most likely problem.
And to answer the other questions specifically,
No, it isn't normal, and
It's already got cylinder/ring wear or another leak path to let oil from
the crankcase to the high pressure side and into the tank.
Could also be a gasket failure or other mechanical problem besides rings
but they're probably highest likelihood.
Sounds line oil blow-by to me. Chances are, the compressor will be about
shot tomorrow, or in another dozen years or so. I've know of compressors
that did that for many years and still worked just fine. Just use care or
get a line filter for paint spraying.
