"burp" valve rises when engine is hot?
Hi All
Is the burp valve on the coolant reservoir supposed to rise on it's own when the engine is at operating temp? Mine always does and I don't know if it is supposed to. It drops back down again when the car is cold.

+1 Normal for 997 but not for the 996/986 cars. System could be burbed when hot by raising the valve. I questioned whether or not my valve was working correctly after I got my 997 because of the way it worked in the Boxster. As it looks like the very same valve I figured they worked the same way.
