Crankcase Vent Valve/Oil Separator
I have a BMW 530I 2001. The dealer showed me the following message:
"Found frozen oil/water mix in valve cover when topping oil off, needs crankcase vent separator, cyclone separator. System not removing moisture. Oil cap was frozen onto engine".
The dealer says it is the Oil Separator/Crankcase Vent Valve/PCV Valve that froze in the cold weather and they have an insulating kit that will fix it. It will cost me $1000 if I have the dealer fix it.
My question is how straight forward is the install of the kit yourself for a guy that can do minor mechanical repairs on cars? Also, does the kit work to eliminate the freezing of this valve? Is there anything else a person should do besides the kit?
