No oil drops at all. Just some smoke when running. My hose goes back to the front of the fuel tank and is open to the atmosphere also.on average if all the ps engines were not leting any oil out of the ccv nobody would do this to keep the boots from blowing off the intercooler tubes. as far as the smell I agree just dont believe the lack of signs of oil.
It is when I did the CCV mod I plugged the hole in the plastic coupler instead of the 4X4 pipe.
