Milky and bubbly oil is a sign of water in the oil. If there was water in the reservoir or pump and it was 15 degrees outside the water may have froze in the pump. This could have caused restricted flow and excess pressure to build up on the supply side (Like blowing into a straw that's pinched off at the end), causing the oil to spray out of the vent hole. If your pump is functioning and the line was blocked with ice and the relief valve was also froze or bypassing, this may explain all of the issues. If it has been sitting for a while, normal condensation inside the pump may have caused the water to accumulate. See if you can get all of the old oil out, add fresh oil, run it a bit and then drain and re-fill it again. A good system flush and you may be in business. Any other ideas guys?
Was the engine itself smoking or was the drive belt smoking while engaged? If the belt was smoking, this may be because it was trying to drive a frozen or high/over pressured pump. Hopefully no seals were blown if this is the case.
Check the rear end oil too. If it's milky or foamy, change it too. Good luck and keep us posted. Oil is A LOT cheaper than bearings and pumps!
