sometimes it does it while hot and sometimes while cold.

if it did it when cold and didn't when hot, then I wouldn't even care and live with it but with it so random.....It's really starting to annoy me

Sometimes vacuum leaks will suck the leak closed, have you tried to pressurize the vacuum lines and use soap & water to look for bubbles... Pressure will blow the hole open when vacuum may suck it closed....

Cold temperature may make the hose stiffer and when it gets warm it becomes more pliable...
