so the number 4 cylinder is on the passenger side? Also I forgot to note that I just started noticing this leak as soon as I mounted my compressor back on. The reason the compressor wasnt on there first is because I had to get a new mount. This is a B18 engine in a 99 Civic EX. Do yall think it could be anything to do with the AC? If not then what hoses should I check? Arent all cars supposed to leak a little when the AC is on?
