| I've been noticing recently that at idle and usually after coming to a stop, randomly gray smoke will pour out of the back of the Z. If I put a little load on the engine and pull forward even 2 ft, the smoke stops. Boosting at WOT it doesn't smoke. It doesn't do it all the time, but mostly happens at idle or after coming to a stop. Search revealed that there could possibly be a leak in the brake master cylinder and it's randomly pulling in brake fluid. Is that a possibility? The motor runs great @ 181K. I also have stock injectors. Could it be that an injector is dumping a little too much fuel at times? I don't have cats on the car currently. Would unburnt fuel still turn into gray smoke in the exhaust? My turbos are also stock originals too. Could it be turbos?
