{"text":"Here's a question I saw on Reddit/trucking, which seems to be 90% newbies. Anyway, anyone got any ideas? I wouldn't mind knowing the answer myself.\n\n\"For the past few days, I've been hearing a constant hiss coming from my tractor valve. It doesn't happen all the time but if it does, it will go on for the entire day. \n\nI just brought it into a shop and we could not recreate it no matter what. The guy obviously is writing me off because I don't know much about trucks (only been in one for 11 months), but I know it's there as when it happens, it will happen for ####### hours.\n\nIf I'm driving and it happens, I'll watch the psi drop to 100 then the compressor kicks in and this will happen repeatedly. \n\nIn the shop today, nothing, no leaks whatsoever. \n\nAm I going crazy or has this happened to someone else? Any tips on how to get it to happen?\"\n\nSomeone help the poor guy out lol\n","pics":"[]","canComment":true}
