Questions tagged [leak]

Questions related to leaks of operating fluids, control vacuum, or in the intake or exhaust systems. For leaks in the bodywork (e.g., rain coming in) use the [water-leak] and/or [body-work] tags. Also consider using fluid specific tags, for example add [coolant] if you have a known coolant leak.
