Engine oil breather line
Author Last Post
There should also be a small 1/2" or so  lengthwise slit in the rubber connecting hose between the engine breather elbow and the breather pipe on top of the engine. This slit will allow crancase pressure to escape in the event the breather pipe outlet freezes over due to condensation in cold weather. If crankcase pressure is not relieved, it can blow oil out of the engine thru the prop seal.
 
Or, you can simply go to Home Depot and get pipe insulation and install it for a couple of bucks.  Put tie wraps on, and you are good to go.

I use the pipe insulation like what you use for copper pipes at home.  You can get the kit from Cessna I believe or you might find it at one of your approved aviation stores in town......

New 185 plane owner here. Does anyone insulate the oil breather line (line that runs across the top of the engine)? The PO stated that in cold weather this should be insulated to prevent condensation dripping on top of motor. Plane from Texas. If it does need to be insulated what material is used?  I fly in cold weather and the pipe is not insulated.
