Hi Kraig,

Just doing some catch-up on the forum and read of your plight with the launching dip stick. The breather hose iced up on the Billet Breather Cover causing crankcase pressure to build and blowing out the safety valve...which in this case is the dip stick. I don't think you caused any engine damage as you still had 2 pints in the crankcase. As a disclaimer, I do have this noted in the breather cover instructions;

"NOTE When operating engine in below freezing conditions, it is suggested that breather hose be disconnected from brass elbow. Testing has shown that ice can form in hose blocking breather function completely. This can result in high crankcase pressures with the possibility of dip stick or oil seals being blown out."

I learned this when testing the prototype cover on my 1250. Fortunately, my engine was idling when the dipstick blew out and banged against the underside of the hood, followed by some huffing and chuffing sounds.

Your engine will be fine...not to worry.

Dave
